Safety & Maintenance instructions, Warnings and Notes

2. Safety & Maintenance instructions, Warnings and Notes

2.1 Safety instructions for repairs

Safety regulations require that during a repair:

• Due to the EM2E concept, a very large part of this chassis (incl. Hor. & Vert. deflection) is 'hot'. Therefore the set must be connected to the mains via an isolating transformer.

• Safety components, indicated by the symbol h, should be replaced by components identical to the original ones.

• When replacing the CRT, safety goggles must be worn.

Safety regulations require that after a repair, the set must be returned in its original condition. In particular attention should be paid to the following points:

• General repair instruction: as a strict precaution, we advise you to resolder the solder joints, through which the horizontal deflection current is flowing, in particular:

– All pins of the line output transformer (LOT); – Fly-back capacitor(s); – S-correction capacitor(s); – Line output transistor; – Pins of the connector with wires to the deflection coil; – Other components through which the deflection current

flows. Note: This resoldering is advised to prevent bad connections due to metal fatigue in solder joints and is therefore only necessary for television sets older than 2 years.

• The wire trees and EHT cable should be routed correctly

and fixed with the mounted cable clamps.

• The insulation of the mains lead should be checked for

external damage.

• The mains lead strain relief should be checked for its

function in order to avoid touching the CRT, hot components or heat sinks.

• The electrical DC resistance between the mains plug and

the secondary side should be checked (only for sets which have a mains isolated power supply). This check can be done as follows: – Unplug the mains cord and connect a wire between the

two pins of the mains plug;

– Set the mains switch to the 'ON' position (keep the

mains cord unplugged!);

– Measure the resistance value between the pins of the

mains plug and the metal shielding of the tuner or the

aerial connection on the set. The reading should be

between 4.5 MΩ and 12 MΩ.

– Switch off the TV and remove the wire between the two

pins of the mains plug.

• The cabinet should be checked for defects to avoid

touching of any inner parts by the customer.

2.2 Maintenance instructions

It is recommended to have a maintenance inspection carried out by a qualified service employee. The interval depends on the usage conditions:

• When the set is used under normal circumstances, for

example in a living room, the recommended interval is 3 to 5 years.

• When the set is used in circumstances with higher dust,

grease or moisture levels, for example in a kitchen, the recommended interval is 1 year.

• The maintenance inspection contains the following actions:

– Execute the above-mentioned 'general repair

instruction'.

– Clean the power supply and deflection circuitry on the

chassis.

– Clean the picture tube panel and the neck of the picture

tube.

2.3 Warnings

• In order to prevent damage to IC's and transistors, all highvoltage flashovers must be avoided. In order to prevent damage to the picture tube, the method shown in Fig. 2-1 should be used to discharge the picture tube. Use a highvoltage probe and a multimeter (position VDC). Discharge until the meter reading is 0 V (after approx. 30 s).

•w All IC's and many other semiconductors are susceptible

to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and tools also at this same potential.

• Together with the deflection unit and any multipole unit, the used flat square picture tubes form an integrated unit. The deflection and the multipole units are set optimally at the factory. Adjustment of this unit during repair is therefore not recommended.

• Be careful during measurements in the high-voltage section and on the picture tube.

• Never replace modules or other components while the unit is switched ON.

• When making settings, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable.

• Wear safety goggles during replacement of the picture tube.

2.4 Notes

• The direct voltages and oscillograms should be measured with regard to the tuner earth (H) or hot earth (I).

• The direct voltages and oscillograms shown in the diagrams are indicative and should be measured in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz.

• Where necessary, the oscillograms and direct voltages are measured with (D) and without (E) aerial signal. Voltages in the power supply section are measured both for normal operation (G) and in Standby (F). These values are indicated by means of the appropriate symbols.

• The picture tube PWB has printed spark gaps. Each spark gap is connected between an electrode of the picture tube and the Aquadag coating.

• The semiconductors indicated in the circuit diagram and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

• Manufactured under license from Dolby Laboratories Licensing Corporation. DOLBY, the double D symbol and PRO LOGIC are trademarks of Dolby Laboratories Licensing Corporation.

NEX

IEW

Today, most broadcasters in Europe, are offering teletext pages containing

their programme schedule of today.These pages can be requested by switching

the TV to Teletext Guide.

An increasing number of broadcasters are offering an extended programme

guide service called

NEX

IEW

NEX

IEW

is a new way of presenting

programme schedules and offers more features than common teletext.

With

NEX

IEW

it is possible to show for instance all the movies coming

tonight.

Both facilities are integrated in this TV:

NEX

IEW

and Teletext Programme

Guide. If a TV channel supports

NEX

IEW

then the TV will automatically

present the

NEX

IEW

programme schedule. If the TV channel supports just

teletext, then the TV will switch automatically to Teletext Guide.

Both facilities are offering the same functions: record, remind and info.

However in case of Teletext Guide the broadcaster is responsible if these

functions are possible.

You can search for the programmes you want to watch up to 7 days in

advance. It is also possible to search for a programme by theme, e.g.sport,

movie, etc. Once a programme has been selected it can be tagged, to remind

you, or to record on the video recorder automatically (provided the video

recorder is equipped with

NEX

IEW

Link, level 2.0), once,daily,weekly or

series.Teletext Guide/

NEX

IEW

also allows direct access to detailed

information about programmes if provided by the broadcaster.

The broadcaster is responsible for the contents of the information.

The TV is responsible for the capture of that information and for the presentation to

the user.

Teletext

Most TV channels broadcast information via teletext.

Each channel which broadcasts teletext transmits a page with information on

how to use its teletext system. Look for the teletext page with the main

index (usually p. 100).

Depending on the TV channel, teletext is transmitted in different systems.

The colours used in the options line correspond with the colour keys of your

remote control.

About Easy Text

Easy Text considerably reduces the waiting time (on condition that the

teletext broadcast of the particular TV channel is received for at least half a

minute) by :

• a direct selection of previous and following pages which are in transmission

and of the pages referred to in the options line

• a habit watcher list: frequently used pages are put automatically in a list of

preferred pages, so that they are immediately available

• the precapturing of the page numbers referred to in the displayed page

• the precapturing of all the subpages.

Switch Teletext on and off

Press b to switch the teletext on or off.

characters used in your language, press the X key repeatedly to select Language

group 1 or 2.

Select a Teletext page

With the digit keys

Enter the desired page number with the digit keys.

• F1F-F2F-F3F, etc.: Test points for the CRT-panel circuitry.

• SC1-SC2-SC3, etc: Test points for the SCAVEM circuitry.

The numbering is done in a for diagnostics logical sequence; always start diagnosing within a functional block in the sequence of the relevant test points for that functional block.

5.2 Service modes and ComPair

5.2.1 Service Default Mode (SDM)

The purpose of the SDM is to provide a situation with predefined settings to get the same measurement results as given in this manual.

Specification of the SDM:

• Tuning frequency 475.25 MHz.

• TV-system for BGLM sets set to BG.

• All picture settings at 50 % (brightness, colour, contrast,

hue).

• All sound settings at 50 % except volume at 25 % (so bass, treble, balance at 50 %, volume at 25 %).

• All service-unfriendly modes are disabled (like sleep timer, child lock, blue mute, AVL and SDLP).

Entering the SDM can be done in 4 ways:

• Via a standard RC-handset by entering the code '062596' followed by the 'MENU' button (it is possible that, together with the SDM, the main menu will appear. To switch it off, push the 'MENU' button again).

• Via ComPair.

• By the 'DEFAULT' button on the DST while the set is in the

normal operation mode.

• By short-circuiting for a moment the two solder-pads with the indication 'SDM' (item 4006) on the A-side of the SSB (activation can be performed in all modes except when the set has a problem with the main-processor).

Note: If the SDM is entered via the pins, all the softwarecontrolled protections are de-activated.

Exiting the SDM can only be done via the STANDBY command. By switching off-on the set with the mains switch the set will come up again in the SDM.

5.2.2 Service Alignment Mode (SAM)

The purpose of the SAM is to align the set and/or adjust the settings.

Specification of the SAM:

• Software alignments (see chapter 8).

• Option settings (see chapter 8).

• Error buffer reading and erasing. The most recent error

code is displayed on the left side.

• Operation counter.

• Software version.

Entering the SAM can be done in 4 ways:

• Via a standard RC-handset by entering the code '062596' followed by the 'OSD' button [i +] (it is possible that, due to the button sequence, the channel will change to channel 9. To return to the channel of your selection, push the appropriate button on the RC).

• Via ComPair.

• By the 'ALIGN' button on the DST while the set is in the

normal operation mode (or SDM). Enter the password '3140' and press OK.

• By short-circuiting for a moment the two solder-pads with the indication 'SAM' (item 4005) on the A-side of the SSB (activation can be performed in all modes except when the set has a problem with the main-processor).

Note: If the SAM is entered via the pins, all the software controlled protections are de-activated.

The Service Alignment Mode menu will now appear on the screen. The following information is displayed:

• Date: the software date.

• ID: the software version of the ROM (Example:

EM2E11.0_01501. This software-code stands for EM2E (chassis), E = Europe, 1 = language, 1.0 = software version, xxxxx = latest 5 digits of 12nc code software).

• Operation Hours: the accumulated total of operation hours.

• Errors: followed by maximal 10 errors. The most recent

error is displayed at the upper left. For explanation errors see (table 5.1).

• Defect. Module: here the module that generates the error is displayed. If there are multiple errors in the buffer that have not all been generated by a single module, there is probably another defect. The message 'Unknown' will then be displayed here.

• Reset Error Buffer: pressing the 'OK' key can reset the error buffer.

• Functional Test: all devices are tested via the 'OK' key. Eventual errors are displayed in the error buffer. The error buffer is not erased, the content returns when the Functional Test is terminated.

• Alignments: this enables the Alignments sub-menu to be called up.

• Dealer Options: extra features for dealers.

Exiting the SAM can be done via the 'MENU' command or via switching OFF-ON the set with the mains switch.

5.2.3 Customer Service Mode (CSM)

All EM2E sets are equipped with the 'Customer Service Mode' (CSM). This 'Customer Service Mode' is a special service

• B = country (E = Europe, A = Asian Pacific, U = USA)

• C = 1 (language cluster)

• X = main version number

• Y = sub version number

Details on the software version can be found in the chapter 'Software Survey' of the publication 'Product Survey - Colour Television'.

Line 2: Code 1; gives the last 5 errors of the error buffer. As soon as the built-in diagnose software has detected an error the buffer is adapted.

Line 3: Code 2; gives the first 5 errors of the error buffer. As soon as the built-in diagnose software has detected an error the buffer is adapted. The last occurred error is displayed on the leftmost position of code 2. Each error code is displayed as a 3 digit number. When less than 10 errors occur, the rest of the line(s) is (are) empty. In case of no errors the text 'No Errors' is displayed. See paragraph 5.5 of this chapter for a description of the error codes.

Line 4: LS Volume; gives the Last Status of the volume as set by the customer for this selected transmitter. The value can vary from 0 (volume is minimum) to 24 (volume is maximum). Volume values can be changed via the volume key on the remote control handset.

5.4 ComPair

5.4.1 Introduction

ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products. ComPair is a further development on the DST service remote control allowing faster and more accurate diagnostics. ComPair has three big advantages:

• ComPair helps you to quickly get an understanding how to repair the EM2E in short time by guiding you step by step through the repair procedures.

• ComPair allows very detailed diagnostics (on I is therefore capable of accurately indicating problem areas. You do not have to know anything about I yourself; ComPair takes care of this.

• ComPair speeds up the repair time since it can automatically communicate with the EM2E (when the micro processor is working) and all repair information is directly available. When ComPair is installed together with the SearchMan EM2E electronic manual, schematics and PWB's are only a mouse-click away.

ComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The ComPair interface box is connected to the PC via a serial or RS232 cable. In case of the EM2E chassis, the ComPair interface box and the television communicate with each other via a bi-directional service cable.

television. These commands are translated by the controller to

C commands and vice versa. In this way it is possible for

I ComPair to communicate (read and write) to devices on the I

busses of the EM2E.

Manual information gathering

Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extend. When this is not the case, ComPair will guide you through the fault finding tree by asking you questions and showing you examples. You can answer by clicking on a link (e.g. text or an oscillogram) that will bring you to the next step in the faultfinding process.

A question could be: Does the screen give a picture? (Click on the correct answer) YES / NO An example can be: Measure test point I7 and click on the correct oscillogram you see on the oscilloscope

Figure 5-4

By a combination of automatic diagnostics and an interactive question/answer procedure, ComPair will enable you to find most problems in a fast and effective way.

Additional features

Beside fault finding, ComPair provides some additional features like:

• Uploading/downloading of pre-sets

• Managing of pre-set lists

• Emulation of the Dealer Service Tool

The ComPair fault finding program is able to determine the problem of the defective television. ComPair can gather diagnostic information in 2 ways:

1. Communication to the television (automatic)

2. Asking questions to you (manually)

ComPair combines this information with the repair information in its database to find out how to repair the EM2E.

Automatic information gathering

Reading out the error buffer, ComPair can automatically read out the contents of the entire error buffer. Diagnosis on I

5.4.2 SearchMan (electronic service manual)

When ComPair is installed in combination with SearchMan, all schematics and PWB's will be directly available while you repair a television if you click on a PWB or schematic link. Example: Measure the DC voltage on C2568 (PWB/schematic) on the small signal level. Clicking on PWB will automatically pop-up a picture of the PWB with the location of C2568 marked. Clicking on schematic will automatically pop-up the schematic with the location of C2568 marked.

5.4.3 Stepwise Start-up / Shutdown feature of set can be used via ComPair

Under normal circumstances, a fault in the power supply or an error during start-up will switch the television to protectionmode. ComPair can take over the initialisation of the television. In this way it is possible to distinguish which part of the start-up routine (hence which circuitry) is causing the problem.

Stepwise start-up explanation

Via ComPair the stepwise start-up can be realised. This is very helpful when a protection is activated (see also chapter 5.6).

5.5 Error codes

5.5.1 Reading error codes from the error buffer

The error buffer can be read in 3 ways:

1. On the screen via the Service Alignment Mode (SAM). In case picture is OK, the error buffer can be read easiest via the SAM. In the main menu of the SAM the last 10 different error codes occurred are displayed. The most recent detected error code is displayed on the left side, so e.g.:

– 0 0 0 0 0 means no error codes present in the buffer – 3 0 0 0 0 means one error code present in the buffer;

error code 3

– 2 3 0 0 0 means two error codes present in the buffer;

error code 2 is the most recent, error code 3 is detected before 2.

2. Via the blinking LED procedure. The contents of the error buffer can also be made visible through the “blinking LED” procedure. This is especially useful when there is no picture. There are two methods: – When the SDM is entered, the LED will blink the

number of times, equal to the value of the last (newest) error code (repeatedly).

– Via the 'DIAGNOSE' key of the DST. If an error has

been detected by the EM2E chassis, the set might go into protection. Without the presence of a picture, the errors can be displayed via the red LED on command of the DST, as long as the main-processor is still active. To display the errors via the red LED by the DST:

1. Press the 'DIAGNOSE' key (in all modes except the SAM).

2. Press '1' to view the last error detected (or '2', etc. to show the errors before).

3. Press the 'OK' key. The blinking Red LED on the TV will now give the requested error.

Example: Error code position 1 - 2 - 3 - 4 - 5 Error buffer: 12 - 9 - 5 - 0 - 0

After entering SDM: blink 1x long (750 ms for tens)

- pause (1.5 s) - blink 8 x short (250 ms for units) etc. After transmitting 'DIAGNOSE-2-OK' with the DST: blink 9 x short - pause (250 ms) - blink 9 x short etc. After transmitting 'DIAGNOSE-3-OK' with the DST: blink 5 x short - pause (250 ms) - blink 5 x - etc. After transmitting 'DIAGNOSE-4-OK' with the DST: nothing happens

3. Via ComPair.

5.5.2 Clearing the error buffer

The error buffer can be cleared in 3 ways:

1. In the SAM by selecting the item 'RESET ERROR BUFFER' in the main menu.

2. By the 'DIAGNOSE 99' command of the DST (in all modes except the SAM). Press the DIAGNOSE key on the DST, followed by 9, 9 and then 'OK'.

3. Via ComPair.

Note: When error buffer is full (10 codes), no new error can be stored anymore. However of every error raised is monitored how long it exists in the error buffer. When for any reason a false raised error exists in the buffer, it will be deleted after 50 hours. If this error is still present after 50 hours, it will be raised again. In this way it is safeguarded that the error codes history is stored. Sometimes it is an option to first write down the error buffer content, reset the buffer, and look again which error codes are generated by the set.

5.6 Protections

5.6.1 General

The EM2E has only one micro-processor (OTC) which remains active during Standby. This because power of the microprocessor and the attached memory chip set is coming from the 3V3 supply, which is derived from the 5V Standbycircuitry. So in both Power-on as in Standby-mode the microprocessor is connected to this power supply.

If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection-mode. The protection-mode is indicated by blinking of the red LED at a frequency of 3 Hz. In some error cases the micro processor does not put the set in the protection-mode. The error codes of the error buffer can be read via the service-menu (SAM), the blinking LED procedure or via DST/ComPair. The DST diagnose functionality will force the set into the Servicestandby, which is alike the usual Standby, however the microprocessor has to remain in normal operation completely.

To get a quick diagnosis the EM2E has 3 service-modes implemented:

• The Customer Service Mode (CSM).

• The Service Default Mode (SDM). Start-up of the set in a

predefined way.

• The Service Alignment Mode (SAM). In this mode items of the set can be adjusted via a menu and with the help of test patterns.

Both SDM & SAM modes can be entered via the 'service pads' on the SSB, via a RC (DST or standard RC) or via ComPair. The SAM can not be entered in Standby, the set has to be in normal operation.

The EM2E 'Protection Diagram' shows the structure of the protection system. See diagram below.

Figure 5-5

There are several types of protections:

C related protections

• I

• OTC related protections (via polling on I/O pins or via

algorithms).

• HOP related protections (mainly for deflection items).

• Hardware errors which are not sensed by the OTC (e.g.

BRIDGE_PROT)

C related protections

In normal operation some registers of the I will be refreshed every 200 msec. During this sequence the

C-busses and the I2C -IC's as well will be checked. The I2C

C controlled IC's

Page 26

GB 26 EM2E5.

Service modes, error codes, protections, faultfinding and repair tips

protection will take place if the SDA and SCL are whether short circuited to ground or to each other. An I occur, if the power supply of the IC is missing (e.g. TUNER_PROT (error 12) & FBX_PROT (error 16)).

OTC related protections

If a protection is detected at an input of the OTC, all protection inputs of the OTC will be scanned every 200 msec. for 5 times. If the protection on one of the inputs is still activated after 1 sec., then the set will be put in the protection-mode. Before the scanning is started a so-called ESD-refresh will be carried out first, because the interrupt on one of the inputs may be caused either by a FLASH or by ESD. As a FLASH or ESD can harm the settings of some IC's, the HOP-HIP-MSP-PICNIC-NVM and Tuner are initialised again to ensure the normal picture and sound conditions of the set.

• 8.6 V and 5.2 V protection. The presence of the 8.6 V and

5.2 V is sensed by the OTC. If these voltages are not present, then an error code is stored in the error buffer of the NVM, and the set is put in the protection-mode.

HOP related protections

Every 200 msec. the status register of the HOP is read by the OTC via I inputs of the HOP, then the relevant error bit in the HOP register is set to ‘high’. If the error bit is still ‘high’ after 1 sec., the OTC will store the error code in the error buffer (NVM) and depending on the relevancy of the error bit the set will either go into the protection-mode or not.

• HFB: Horizontal Flyback. If the horizontal flyback is not

• Flash detection. From the EHT-info, via D6303 and T7303

C. If a protection signal is detected on one of the

present, then this is detected via the HOP (HFB_XRAY_PROT). One status bit is set to ‘high’. The error code is stored in the error buffer and the set will go into the protection mode

a flash will stop the H-drive and line output stage immediately. The FLS-bit in the status register of the HOP is set to ‘high’. As the duration of a flash is very short the FLS-bit will be reset to ‘low’ again after the flash refresh, so via a slow start the set will be started again.

C error can also

Hardware related protections

Due to the architecture (with 'hot' deflection) there are two protections that are 'unknown' to the microprocessor, namely the 'BRIDGE_PROT' from the line-stage and the 'NO_VFB' protection form the frame-stage. If one of these protections is triggered, the set is positioned in ‘Standby’-mode. The OTC will now try to re-start the set. If this will not succeed after 5 times (after ≈ 1 minute), the OTC will generate error 15 (Flash protection) and will start the blinking red LED.

The start-up of the set is very different as of other sets:

1. When the set is switched ‘ON’, first the HOP is placed in 'low power start-up' mode (HOP-standby-mode). This means that 5 V (derived from available Standby-supply) is connected to pin 22 of the HOP-IC.

2. Now the HOP is driving the line-circuitry with 50 kHz pulses. At the base of the line-transistor this is sensed via the 'STANDBY’-line.

3. This signal triggers the Main supply to operate. Now the line-stage has 'BAT'-voltage (141 V), it will also start.

4. After the 5 and 8 V-supply lines are sensed by the OTC, it will read the POR-bit from the HOP via the I

5. Now the HOP is switched in ‘ON’-mode and the set will start-up further with normal drive (31.25 kHz for PAL).

6. The last step will be the unblanking of the picture.

SO STANDBY IS NOT CONTROLLED VIA A STANDBY-LINE FROM MICROPROCESSOR, BUT IS ACHIEVED INDIRECTLY VIA THE HOP-CIRCUITRY.

Notice that a very big part of the set (Large Signal Panel) is 'hot', meaning the primary part of the Standby supply, the whole Main supply (except for the secondary Audio supply) and the complete deflection circuit. SO NOTICE THAT THE DEFLECTION-COIL IS HOT!

This set does not have an IR transmitting-LED anymore. In its place, a Service (ComPair) connector is implemented at the rear of the set, which is directly accessible. In addition to this, there is a blinking LED procedure to show the contents of the error buffer.

The relay you hear during switching 'ON' (via the main switch) is from the degaussing-circuitry. So it is not used for switching the supply as in the MG-chassis.

When using ComPair (connect cable to ComPair-connector at the rear of the set, placed behind a separate cover), there exists the possibility to have a stepwise start-up procedure. With this mode one can startup the set step-by-step. This also means that in certain steps some protections will not be activated. This can sometimes be convenient during repair. See table in 5.4.3, which is describing the stepwise start-up mode with belonging LED behaviour.

On the SSB there are 'service pads' implemented to activate (via bridging) the SDM- or SAM-mode (see chapter 4). When the SDM-mode is activated, the processor-controlled protections (so not the Hardware and HOP-protections) can be overruled. This means that the ADC-input protections (5- and 8 V) and the I

C not-acknowledging info from Tuner and FBX can be overruled. WHEN DOING SO THE SERVICE-ENGINEER MUST KNOW WHAT HE IS DOING, AS IT COULD LEAD TO DAMAGING THE SET.

'Repair-tips how to repair the Main power supply:

• Simplest way is to replace components of the Main supply

with repair kit (3122 785 90100)

• More detailed way:

– Replace FET 7504 and zener 6505 – Remove SSB-panel – Short-circuit BE of TS7529 in order to put supply in

Service-tips:

• Be careful measuring on gate of FET 7504. Circuitry is very high ohmic and can easily be damaged.

• Take care not to touch ‘hot’ heatsink while disconnecting SSB, despite the fact that mains cord is out of mains socket. There still is an annoying rest-voltage for a short while.

• Do not try to measure on side of SSB directed to the hot heatsink. This is dangerous. All service test points are guided to the Tuner side and are pointed out by service printing. Where the circuitry was too crowded to place this service-printing it has been explained on the Test point overviews in this manual

Regardless the mode of the set, this voltage should always be available. No picture, red LED (high intensity) despite expectation the set should be ‘on’ (this looks like Standby).

There are 2 protections that are not 'seen' by processor, that force set in ‘Standby’-mode, namely 'NO-VFB-prot’ (= no frame-deflection), or 'BRIDGE_PROT' (safety error).

If protection is activated by ‘NO_VFB-prot’, this can be measured with a

scope on service test point F10 (diagram A4). Before this protection is

activated, a few seconds a horizontal white line is visible.

The 'BRIDGE_PROT' error may never occur. Is implemented due to legal

requirements. Flash protection error (15) will be generated in both cases

after 5 restart attempts.

Set is in protection due to various causes. For error codes see error-code list.

You have no picture, so:

8. Electrical alignments

GB 71EM2E 8.

8.1 General alignment conditions

All electrical alignments should be made under the following conditions:

• Power supply voltage: 230 V ± 10 %; 50 - 60 Hz ± 5 %. Should be applied via an isolating transformer with low internal resistance.

• Warm-up time ≈ 20 minutes.

• Voltages and oscillograms are measured in relation to

Tuner earth (with exception to the voltages on the primary side of the power supply). Never use the cooling fins/plates as ground: they are 'hot' ! ! !

• Test probe: Ri > 10 MΩ, Ci < 20 pF.

• Use an isolated trimmer/screwdriver for the alignments

8.2 Alignments on the large signal panel (LSP)

Large Signal panel (LSP)

Elucidation: In the frame blanking period of the R, G and B signals applied to the CRT, a measuring pulse with different DC levels is inserted by the 'HOP' video processor. Measure the black level pulse during the vertical flyback at the RGB cathodes of the CRT.

1. Put the set in the SDM mode (see chapter 5.2.1).

2. Insert a black test-pattern signal (carrier 475.25 MHz) to the Tuner input.

3. Connect an oscilloscope (position 50 V/Div DC and 2 ms/ Div) alternately to the CRT cathodes (Red pin 8, Green pin 6, Blue pin 11) and measure for each cathode the DC level of the measuring pulse (see elucidation above and figure 8-

2) and write down each value. Remark: Trigger the scope external via a CVBS signal (for instance via pin 19 of the SCART1 connection).

4. Adjust the Vg2 potentiometer (lower potmeter, see figure 8-

1) so that the measuring pulse with the highest noted level is on 160 ± 3 V

level.

8.3 Vertical amplitude alignment

1. Tune the set to a crosshatch test pattern (use an external video pattern generator).

Put the set in the SAM mode (see chapter 5.2.2). The Service Alignment Mode menu will now appear on the screen. Via 'Alignments' the following submenu's can be selected:

• General:

– Drive – Luminance Delays – EHT Compensation – Soft clipper – Luma gain – IF AFC – Tuner AGC – Blend intensity – Adjust Peak White Limiter – Vg2 Test Pattern

• Normal Geometry: General geometry alignments.

• Super Wide Geometry: Geometry alignments for the

'Panorama' position in 16:9 sets (only valid for wide screen sets; alignments can be performed, however, it is better to set values as mentioned below).

• Options: Setting the initialisation codes in the set via text.

• Option Numbers: All options together, expressed in two

long numbers. The original factory setting for these numbers can be found on the picture tube sticker on the inside of the set.

• Store: Store all alignments.

Page 34

GB 72 EM2E8.

Electrical alignments

The alignments are explained now in the sequence of the submenu:

8.5.2 'General' alignments in Service Alignment Menu:

• Once all alignments/settings have been completed the item 'Store’ must be selected to record all the values in the permanent memory of the set.

• If the Option codes have been changed and stored, the set has to be switched 'OFF' and 'ON' using the mains switch to activate the new settings (when switching via Standby, the option code settings are NOT read by the microprocessor).

• If an empty EAROM (permanent memory) is detected, all settings are set to pre-programmed default values.

• A built-in test pattern can be called up in various submenus. The test pattern generator can be switched on using the item 'Test pattern on/off'. The test pattern only appears AFTER the specific alignment has been selected. The test patterns are generated by the Teletext-IC (OTC).

'Drive'

• Method 1 (with colour analyser):

1. If you want to align tint-settings with a colour-analyser,

the Test pattern must be switched on. You get a white block in middle of the image now.

2. Before doing the Tint-settings the 'Cathode'-parameter

must be aligned. This is dependent of the picture tube size and brand. See table “Cathode parameter” for the colour-analyser readings.

3. Tint-settings: Set the white levels for the 3 Tint-settings

'Normal', 'Warm' and 'Cool'. The next values must be aligned (see table “White levels”).

• Method 2 (without colour analyser):

1. Without having a colour-analyser one can set some parameters. This is the next best solution. The settingparameters are average values coming from production (statistics).

2. Before doing the Tint-settings the 'Cathode'-parameter must be set. For all picture tubes the value '5' must be entered.

3. The ‘Tint’ setting must be on ‘normal’.

4. Tint-settings: Set the Red, Green and Blue parameters for the 3 Tint-settings 'Normal', 'Warm' and 'Cool'. See table 8.4 for the values.

5. Red BL offset: herewith the Black Level can be aligned very precise. Pre-set value is 7.

6. Green BL offset: herewith the Black Level can be aligned very precise. Pre-set value is 7.

‘Luminance delays’

With the 'Luminance delays' alignment the luminance information is placed on the chrominance information (brightness is pushed onto the colour). Use a colour bar/grey scale pattern as test signal.

• Lum. Delay Pal: Apply a PAL colour bar/grey scale pattern as a test signal. Adjust ‘Lum. Delay Pal’ until the transients of the colour part and black and white part of the test pattern are at the same position.

• Lum. Delay Secam: Apply a SECAM colour bar/grey scale pattern as a test signal. Adjust ‘Lum. Delay Pal’ until the transients of the colour part and black and white part of the test pattern are at the same position.

• Lum. Delay Bypass: apply a NTSC colour bar/greyscale pattern as a test signal. Adjust value until the transients of the colour and black & white part of the test area are at the same position.

‘IF AFC’

The SAM-mode is needed to make alignment, a test generator to make signal and the Installation-menu to check the 'Fine Tune' value. Supply, via a video generator (e.g. PM5518), a TV-signal with a signal-strength of at least 1 mV and a frequency of 475.25 MHz. Use BG if possible, otherwise match the system of your generator with the received signal in the set.

Alignment procedure:

1. Go to the 'Installation' menu.

2. Select 'Manual installation'.

3. Tune the TV-set to the system and frequency described above via 'Search' - '475' - 'OK'.

4. If the frequency showed in the line 'Fine tune' is between

475.18 MHz and 475.31 MHz, you don't need to re-adjust the IF-AFC.

5. If not, adjust the frequency in the 'Fine tune' line to 475.25 MHz and 'Store' the program (this is very important because this will disable the AFC algorythm).

6. Now go to the SAM and select 'Alignments' - 'General' - 'IF AFC'.

7. During the 'IF AFC'-parameter adjustment, one can see OSD feedback in the top of the screen. The OSD feedback can give 4 kind of messages:

AFC-window AFC-frequency versus reference Out High In High In Low Out Low

The first item (In or Out) informs you whether you are in or out the AFC-window. The second item (High or Low) informs you about whether the AFC-frequency is too high or too low.

1. First you must align the 'IF AFC'-parameter such that you come into the AFC-window (= 'In')

2. Then you must look for the point where the 'IF AFC'parameter changes from High to Low. This level is the value you are looking for.

3. After adjustment 'Store' the value.

4. Now return to the 'Installation' menu.

5. Select 'Manual Installation' - 'Search' - '475' - 'OK' and 'Store'. This will set the AFC 'on' again.

Service-tip: If you do not trust the accuracy of the frequency of your Service-generator, first 'measure' with 'Fine tune'-line (manual install-menu) of a good set your video generator.

‘Tuner AGC’

The SAM-mode is needed to make alignment, a test generator to make signal, a DC-Voltmeter to measure at pin 1 of Tuner.

Supply a TV-signal, with a frequency of 475.25 MHz and a signal-strength of about 2 mV. Measure the DC-voltage on pin 1 of the Tuner (position 1200). With the ‘Tuner AGC’-alignment in the SAM-menu, this voltage can be aligned. Alignment is correct when DC-voltage is just below 3.5 V.

'Blend intensity'

(This alignment could be used when micro controller or HOPIC has been replaced). It aligns the level of transparency of the menu-picture blended into the main-picture.

1. Position the brightness-, contrast- and colour setting in the middle position (picture-menu).

2. Apply a signal with a 100 % white video-pattern.

3. Connect an oscilloscope to pin 7 of connector 0340 of the CRT panel and measure the Red output level.

4. Align 'blending intensity'-parameter such that the blended signal is 65 % of the black-white amplitude. Practically this will be about 1.3 V (blended signal) versus 2 V (full white signal).

5. The parameter can be adjusted in between 0 and 31.

'Horizontal amplitude and centring'

Use an external pattern generator with a geometry pattern (e.g. crosshatch).

1. Using 'H. amplitude' align the horizontal amplitude so that the entire test pattern is visible.

2. Use an external test signal, with a centre-reference from a service-generator. Use 'H shift' to align the picture horizontally in the middle.

3. Repeat the 'H amplitude' alignment if necessary.

'East/west alignment'

Use an external pattern generator with a geometry pattern (e.g. crosshatch).

8.5.3 'Normal Geometry' alignments in the Service Alignment

'Adjust Peak White Limiter'

Depending on the picture-tube size, the next value of the table must be entered:

Peak White Limiter 25" FS 4 28" FS 4 29" SF 4 24" WS 4 28" WS 4 32" WS 4

'Vg2 Test Pattern'

Here the Vg2 Test pattern can be switched on.

Warning: At this moment, the 'INTERNAL TEST PATTERN' of the set software will lead to a mis-alignment of the picture geometry. Therefor use an external generator with a geometry pattern (e.g. crosshatch) to align the set (only for the 'Vertical slope' adjustment the internal test pattern can be used).

'Vertical slope'

Select 'Test Pattern on' (read warning above).

1. Set the start conditions for 16:9 sets: 'V. S-correction' value on 8 for the 28” and on 7 for the 32” set. The boundarystripes of the test pattern should be positioned on the edge of the picture tube.

2. Align ‘V. slope’ (when aligning the below half of the picture is blanked). The middle line of the test pattern must be matched with the edge of this blanking/picture transient in the middle of the picture. Pushing 'MENU' button again, gives you previous menu again. (This alignment is meant to align the zero crossing of the frame-deflection to the mechanical middle of the picture tube.)

Figure 8-3

1. Use 'East/West Parabola' to align the vertical lines until straight.

2. 'Upper East/West corner' to align the vertical lines in the upper corners until straight.

3. 'Lower East/West corner' to align the vertical lines in the lower corners until straight.

4. Use ‘East/West Trapezium’ to align for a rectangular.

5. Use 'Horizontal Parallelogram’ to align for straight vertical lines if necessary.

6. Horizontal Bow' (neutral value 31. With this alignment the E/W parabola can be corrected such that it becomes symmetrical).

8.5.4 'Super wide geometry' alignments (for widescreen sets) in the Service Alignment Menu

The header of this paragraph and also the menu’s are somewhat misleading. We only need to set the following values (if the normal geometry alignment has been performed correctly):

1. V. S-Correction: enter value of 'normal geometry'

9.1.1 Introduction

The EM2E Europe is a lower specified MG-chassis. EM stands for Eco-MG, 2 for the used processor (1 = Painter, 2 = OTC) and E stands for Europe. This will be, at the moment of launch, the cheapest realised 100 Hz set.

The architecture consist of a conventional large signal panel (LSP) and a small signal board (SSB) module, placed into a so called SIMM-connector (Standard Interface, 80 pins).

The LSP is built up very conventional, with hardly any surface mounted components on the copper side. Difference with the MG-chassis is that the EM2E LSP has a very large 'hot' part, including the deflection coil.

The SSB is a high tech module (2 sides reflow technology, full SMC) with very high component density and complete shielding for EMC-reasons. Despite this, it is designed in such a way, that repair on component level will be possible. To achieve this, attention has been paid to:

• The position of service test lands (Tuner side).

• Accessibility (Tuner side).

• Clearance around surface mounted IC's (for replacing).

• Diagnostics & Fault Finding via ComPair.

Due to the low amount of cabling etc., expectation is that the FCR will be low.

Attention: During the first 4 to 6 months of production, the EM2E set-software will be integrated into a flash-RAM on the SSB. After that period, a mask-ROM will be used. Which IC is used is not of interest for service, but for both solutions it means that Service Workshops must be equipped with dedicated (de)solder equipment for exchanging these IC's. In case flash-RAM or mask-ROM has to be replaced in the field, dealer will receive always an up-to-date flash-RAM.

Warning: Be aware that half of the LSP-circuitry is 'hot', including the deflection coil.

Protection: The start-up behaviour of the EM2E is different then that of the MG-chassis, meaning that there does not exist a situation as in the MG where we have 'supply ON / deflection circuit OFF'. This means that isolating failures in the EM2E must be done in a different way. See Chapter 5 of this manual.

The tuner type UV1316 is a PLL tuner and delivers the IFsignal, via audio & video SAW-filters, to the HIP (High-end Input Processor). The HIP has the following functions:

• IF modulation.

• Video source- and record select.

• Colour decoder.

• Synchronisation.

Two SCART-connectors can be used: SCART1 is fully equipped and SCART2 is meant for VCR. Pin 10 of SCART2 is used for Easylink and there is a possibility for Y/C in. The CVBS-out on pin 19 can be used for WYSIWYR (What You See Is What You Record).

The HIP delivers the signal to the PICNIC. This IC takes care of:

• Analogue to Digital conversion and vice versa.

• 50 to 100 Hz conversion.

• Panorama mode.

• Noise reduction.

• Dynamic contrast.

For Digital Scan the PROZONIC is required, which can be connected to the PICNIC. This IC is mentioned as 2fH features in the blockdiagram.

After the PICNIC the, now 100 Hz, YUV- and H/V-signals are fed to the HOP (High-end Output Processor). This IC handles the video control and geometry part. The RGB-signals from TXT/OSD are also inserted via the HOP. The video part delivers the RGB signals to the CRT-panel and the geometry part delivers the H-drive, V-drive and also a drive-signal for rotation (as a variable DC-level on the V-drive signal).

Figure 9-1

Both deflection circuits are 'hot' and located on the LSP and are driven by the HOP. To make the galvanic separation, the line drive is driven via transformer 5410 and the framedrive via optocoupler 7610.The horizontal output stage generates some supply voltages, the EHT-, focus- and Vg2-voltages.

The RGB amplifiers on the CRT-panel are integrated in one IC and are supplied with 180 V from the LOT. The SCAVEM circuit modulates transitions of the Luminance (Y) signal on the horizontal deflection current, giving a sharper picture.

The sound part is built around the MSP34xx (Multichannel Sound Processor) for IF sound detection, sound control and source selection. Dolby decoding is also done by the MSP. Amplification is done via an integrated power amplifier IC, the TDA2616.

The microprocessor, called OTC (OSD, Teletext and Control), takes care of the analogue TXT input- and output processing. The OTC, ROM and RAM are supplied with 3.3 V, which is derived from the +5VSTANDBY. The NVM (Non Volatile Memory) is used to store the settings, the FLASH RAM contains the set software and the DRAM is used for storing the Teletext pages.

In EM2E there is a separate Standby Supply in order to reduce the Standby power consumption. During Standby, the Main Supply is switched off (via TS7529). A relay is used to switch the Degaussing circuit.

The power supply has a number of main functions. These functions are dealt with in succession:

The mains filter has 2 functions: it prevents high-frequency signals to be transferred into the mains and it protects the set from lightning damage.

C2507 prevents the high-frequency signals, generated by the set, to be conveyed into the mains by short-circuiting them.

In case of a lightning surge between the 2 phases (differential mode) the energy is immediately bled away through the VDR (R3509) to the other phase. In case of a lightning surge on both phases of the mains in relation to the aerial earth, the mains filter acts as a high resistance (U

=L * dI/dt) as a result of which the voltage

EMK

across coil L5503/04 increases. A spark gap (0001) prevents that the voltage increases too much, which would lead to a damaged coil. When ignited, the current will be discharged via this spark gap. The two networks using R3503//0002 and R3502//0003 are also used for lightning protection. They lead the energy of a common-mode lightning surge from the 'cold' to the 'hot' side in case of insertion on the aerial or from the 'hot' to the 'cold' side in case of insertion via the mains-input. Resistor R3500 is used for limiting the inrush-current.

For 240 V

mains-voltage applications, jumper 9502 is used.

Diodes 6501 to 6504 now work as bridge rectifier charging C2510. For 110 V 9502, jumpers 9503 and 9504 are used. Now the diodes will

After switching 'ON' the set via the mains-switch, the DEGAUSS_INPUT signal from the processor (OTC) will be made high, transistor 7528 will conduct and relay 1002 will be activated. Initially a considerable current will flow, via PTC 3516, through the degaussing coil. The PTC will heat up, resistance will rise and the current will decay rapidly. The OTC will switch off the relay after 12 seconds.

Standby power supply (diagram A2)

This power supply is of a SOPS type (Self-Oscillating Power Supply) and is regulated by the controlled switching of an oscillator. It uses the so-called 'Flyback' principle:

Time interval t0 - t1: After switching on the set, the gate of MOSFET TS7102 will be high (max. 15 V due to zenerdiode D6105). This will drive the FET into saturation (U

= 0 V). The DC-voltage U

MAINS

will be transposed across the primary winding of L5101 (3, 5) resulting in a linear increasing current through this coil. The voltage across the co-coupled coil (1, 2) is also positive and will keep the FET into conductivity via C2101, R3103, R3102 and R3117 for some time. The slope of the primary current is determined by the self-induction of the coil and on the magnitude of the supply voltage (+375 V). The maximum current is determined by the time the FET stays into conductance (t0 - t1). This time is directly determined by the voltage across R3108//R3118. This voltage is a measure of the current and if it exceeds 1.4 V, TS7101 will be driven into conductivity and consequently connect the gate of TS7102 to earth; the FET will block. The current will be: 1.4 V / (15//4.7 ohm) = 0.39 A. The voltage across the secondary winding (8,9) will be negative, diodes D6111 and D6107 will block.

Time interval t1 - t2: The sudden current interruption in the primary coil, will induce a counter-e.m.f. that wants to maintain the current. The voltage on the drain of the FET will increase. The secondary voltage (8,

9) will become positive and will charge C2104 via D6107 and D6111. All energy that was stored in L5101 during t0 - t1 will be transferred into the load. Due to the transformer principle, a voltage will now be induced in the primary winding (3, 5) and the co-coupled winding (1, 2). This voltage will be: N * U

The voltage across the co-coupled coil will be negative, keeping the FET blocked.

Time t2: At t2, the current through the secondary coil will be reduced to zero, as C2104 is no longer charged. As a consequence, the voltages will decay and will change polarity. The gate of the FET will be again made positive, is driven into conductivity and the cycle starts again.

decrease. At a certain voltage, optocoupler TS7103/04 will block and the oscillator will start again. Since there are no capacitors and there is a high amplificationfactor in the feedback circuit, the feedback is ultra-fast. This is why the ripple on U

is minimal. The negative supply voltage

(-20 V) used in the feedback circuit originates from the cocoupling coil and is rectified through D6103. Stabilisation is not effected through duty-cycle control but through burst-mode of TS7100. Burst-mode is load dependent. If the power supply is less loaded, the secondary voltage will have the tendency to increase more rapidly. If the load on the power supply

increases, then the oscillator stops less often, right up to the moment that the oscillator is operating continuously: maximum load. If the power supply is now loaded even more, the output voltage will decay. The maximum load is determined by the maximum primary current set by R3108//3118.

Protection: If the optocoupler would fail, the secondary voltage will increase. This would have disastrous consequences since many IC's (e.g. OTC, flash-RAM, DRAM) are fed with this 5.2 V. In other words, very expensive repairs would be required. We already know that the negative supply is directly dependent upon the secondary 5.2 V, as a consequence of which the negative supply will increase proportionally as the secondary voltage increases. If the negative supply in the mean time reaches -30 V, D6106 will start to zener and as a consequence TS7101 will start conducting. Basically, D6106 will take over the stabilisation task of the optocoupler, however, with a considerable spread: from -20 V to -30 V is a 50 % increase, thus U

will increase

from 5.2 V to max. 7.5 V.

The FET will be driven into saturation (same as closing switch 'S' ). The drain-current will increase linear in time. With other words: resistors R3513 and R3518 will start the oscillator. The voltage across the co-coupled coil (4, 5) is also positive and will keep the FET into conductivity.

The drain-current will also flow through R3514//R3515. The voltage on the base of TS7502 will be +0.8 V due to the stabilisation circuit (which is explained further). At increasing current, the emitter-voltage of TS7502 will get more negative. When this voltage reaches -0.7 V, TS7502 will be driven into conductivity and consequently connect the gate of TS7504 to earth; the FET will block (same as opening switch 'S'). The maximum drain-current is: 0.7 V / (R3514//R3515) = 1.4 A. The voltage polarities on L5506 will invert, keeping the gate of TS7504 negative via the co-coupled coil (4, 5). The voltage on the secondary winding of L5506 (7, 8) will be positive, generating the +28 V audio supply voltage via D6507 and C2512.

The sudden current interruption in the primary coil, will induce a counter-e.m.f. that wants to maintain the current via the 'freewheel' diode D6508. This current is linear decreasing in time and as it is also flowing through R3414//R3415, TS7502 will be blocked after a certain time period.

will result in an audible hiccuping of the supply).

Set to 'STANDBY" (via RC): When the set is switched to 'STANDBY' via the Remote Control, the Main supply will be switched off. This is done by the circuit around TS7529 (see diagram A1): During 'ON'-state the Main supply is fed with line pulses via the STANDBY line. They are rectified and smoothed via D6517, D6516 and C2530 and fed to TS7529. Because they are less than -20 V, this transistor will be blocked. When these pulses are stopped (STANDBY), TS7529 will be saturated and TS7502 will be switched off. This will switch off the Main supply.

Set to 'ON' (via 'STANDBY'): At the moment the set is switched 'ON', the HOP is not working (as much as possible IC's are made voltageless during 'STANDBY'). Therefore it is impossible that the STANDBY line carries line-pulses, so the main supply cannot start up. This problem is solved via the 'low power start-up' possibility of the HOP. Via pin 22, the HOP receives, via the STANDBY_INFO line from the OTC, a voltage of 5.2 V coming from the Standby supply. The result will be that the HOP will generate pulses with a nominal T

and TON growing from 0 to 30 % of the nominal

OFF

value. This signal is unchanged until the Main supply is switched 'ON' and the HOP the correct I

C-command POR-bit) has received.

Guarding circuit: The negative pulses on the secondary winding of L5506 are rectified by D6520 and smoothed by C2535. The resulting negative DC-voltage will keep TS7510 blocked, even as TS7511.

When something happens in the Main supply through which these pulses will decrease, the DC-voltage will increase. TS7510 starts to conduct, even as TS7511. Via R3541 and D6522 this situation will be maintained (thyristor principle). The collector of TS7511 drives via R3538 a positive pulse back to the OTC (named STANDBY(POR)). The OTC will now switch off the Main supply via the STANDBY_INFO signal.

SSB

There are 5 different voltages located on the SSB: +33 V, +11D V, +8 V, +5.2 V and +5 V. +5.2 V is the Standby voltage, it should always be present. The 8 V is derived from the 11D V with stabiliser 7906. The 11D voltage is only present when the line-drive pulses start the deflection. The 8 V is used to switch the +5.2 V with transistor 7905 to supply the +5 V.

OTC

The SAA5801 (IC7001) is called the OTC (OSD, TXT and Control). In this IC, the microprocessor and the TXT-decoder (level 2.5) are integrated. Some of its functions are:

• Set control.

• TXT/OSD acquisition.

• RGB-outputs to the HOP

• Menu blending; for blending the contrast is software

controlled.

• I/O-ports for I

C, RC5, LED, and service modes.

• Error code generation.

The software for EM2E can be 2 MB (Megabyte). For TXT-data 1000 pages can be stored in IC7007. This is a DRAM of 4 Mbit and this IC is also used to store data of a working set. The Non Volatile Memory IC7011 is a 4 kB version M24C32W6.

All ICs in this part are supplied with 3V3. For this voltage a 3V3 stabiliser is used (IC7005). When the 3.3 V is available, a POR is generated with TS7003/ 7004 to wake up the OTC. During the reset all I/O pins are high. When a POR is generated the TV-set is in Standby mode.

Via pins 105 and 106 the 8 V and the 5 V are sensed. If one of them is not present, the Main supply is switched off (set in protection and the red LED will blink at 3 Hz). The OTC will generate an error code to indicate what was wrong.

The horizontal (HD100) and vertical (VSYNC) sync pulses are also fed to the OTC for stable OSD and TXT.

The RGB-outputs (77/78/79) together with fading (pin 80) are fed to the HOP. The fading pin has a double function: it is used for making a transparent menu and as fast-blanking signal for TXT.

C-busses

In the EM2E-chassis with OTC-processor there are two I busses used:

• Slow (max. 100 kHz) hardware I for all IC communication.

• Separate short bus (called I

C-bus (called I2C1), used

C3) for the Non Volatile

Memory (NVM) to avoid data corruption.

NVM

The Non Volatile Memory contains all set related data that must be kept permanently, such as:

• Software identification.

• Operational hours.

• Error-codes.

• Option codes.

• All factory alignments.

• Last Status items for the customer + a complete factory

recall.

• Txt featuring (keeping habit watch data).

• EPG data.

9.1.5 Tuner & IF (diagram A7 & B2)

The tuner UV1316 is I

C-controlled and is capable of receiving

off-air, S- (cable) and Hyperband channels:

• Low 44 - 156 MHz

• Mid 156 - 441 MHz

• High 141 - 865 MHz

The tuning is done via I

C. The reference voltage on pin 9 is 33 V. This voltage is derived from the 180 V (from the LOT) via a resistor of 120 kΩ and a zenerdiode. The OTC together with the HIP control the tuning procedure. There is also automatic switching for the different video systems.

The IF-filter is integrated in a SAW (Surface Acoustic Wave) filter. The type of this filter is depending of the standard(s) that has to be received. Two SAW filters are used: One for filtering picture-IF and the second-one for sound-IF. An extra filter (5403), tuned at 40.4 MHz, is necessary for L/L’ sets with 6.5 MHz sound to suppress the neighbour channel.

The output of the tuner is controlled via an IF-amplifier with AGC-control. This is a voltage feedback from pin 62 of the HIP to pin 1 of the tuner. AGC take-over point is adjusted via the service alignment mode ’Tuner AGC’. If there is too much noise in the picture, then it could be that the AGC setting is wrong. The AGC-setting could also be mis-aligned if the picture deforms with perfect signal. The IF-amplifier amplifies too much.

The video IF-signal is fed to pins 2/3 of the PLL-controlled IFdemodulator. The voltage controlled oscillator of the PLL is adjusted via the service menu ‘IF AFC’. If the alignment is correct then the displayed frequency in the installation menu is the same as the applied frequency from a generator. The external coil L5408 connected between pins 7/8 is used as reference. The demodulated IF-video signal is available at pin

C-

10 of the HIP. In this video signal there is a rest of sound carrier, which is filtered by the sound trap 1407. Then the signal is again fed to the HIP on pin 12 where the group delay can be corrected, dependent on the standard that is received. On pin 13 the CVBS-signal becomes available which is used for further processing in the television. Via TS7322 the signal is supplied to EXT1 and back into the HIP on pin 14 to the source/record selection.

To realise quasi split sound the IF-signal is fed to the HIP on pin 63/64 via SAW-filter 1405. The FM (or AM for L-norm) modulated signal is available on pin 5 and is fed to the audio demodulator MSP34xx.

9.1.6 Video: High-end Input Processor (HIP, diagram B2))

In the EM2E the TDA932xH input processor is used, which contains the following functions:

• IF demodulation.

• Group delay correction.

• AFC signal generation, used to track drifting transmitters.

• Sound carrier re-generation (SIF).

• AM demodulation.

• Sync acquisition, delivering HA and VA.

• Switching off IF-filtering.

The HIP has various inputs.

• Full matrix switch with: – 2 CVBS inputs – 2 Y/C (or additional CVBS) inputs – 1 CVBS front end input

• Two RGB inputs and 2 status-inputs

Outputs: Three separate switchable outputs can be used:

• 1 YUV-output is fed to the PICNIC

• 2 CVBS outputs: One for Teletext Dual Screen and the

other for output to EXT2 to have WYSIWYR (What you see is what you record)

I/O-switching: The external signals are fed directly to the I/O part of the HIP with status from pin 8 of SCART. On the HIP there are two status inputs available (pins 15, 17) with two voltage levels:

• 4:3 -> 2.2 V

• 16:9 -> 5.5 V

The input signals from the Front I/O are fed to the HIP and front detection is also fed to the OTC. EXT1 is full SCART: thus CVBS and RGB. The RGB-selection is done in the HIP. EXT2 is meant for VCR and has therefore some additional signals in relation to EXT1 but no RGB. EXT2 has also the possibility for Y/C_in and Easylink-Plus (P50). Y_in is with pin 20 and Chroma in with pin 15. Easylink is handled via pin 10 of the SCART and this is a bi-directional communication.

Easylink supports the next features:

• Signal quality and aspect ratio matching

• One touch play

• One touch text

• PIP

• Pre-set download

• WYSIWYR

• Automatic Standby

With Easylink-Plus is added:

• Country and language installation

• System Standby

• Intelligent set top box features

• NexTView download

• Timer record control

• VCR control feature

Video processing

The sandcastle-pulse of the HIP will not be used for synchronisation. The HOP will generate synchronisation signal derived from the feature box (PICNIC) signals. If a VCR is connected, there is also an automatic correction for Macrovision. This is active for the external sources and the presets 0, 90-99. The HIP itself (no external voltage) controls the Y/C switch in the HIP. The chrominance decoder in the HIP is full multistandard: PAL/ SECAM/NTSC. Two different crystals can be connected to the pins 54 & 57 without any alignment. The crystals are also used as a reference for the synchronisation. A digital control circuit that is locked to the reference signal of the colour decoder determines the start-up of the sync. This crystal may only be replaced by the original one. If just a crystal is taken, the internal capacitance will be different and the effect will be that there is no colour. In the HIP a sync separation has been integrated; the HIP delivers the HA and VA 50Hz/60Hz to the PICNIC. On pin 59 there is the 1fH sandcastle but this is not connected to any circuit and only used internally for the colour demodulator. The 2fH-sandcastle signal is generated by the HOP.

9.1.7 Video: Feature box (PICNIC, diagram B3))

Introduction

The basic function of the Feature box (FBX6) is picture improvement, and depending on the version, several scan conversion methods can be applied. The PICNIC (SAA4978H) is the central key component. In the EM2E-chassis the featurebox is integrated on the SSB. The PICNIC is used for the 100Hz conversion. In the PICNIC the following functions are present:

• The ADC.

• The DAC.

• The 100 Hz conversion.

• The Panorama mode.

• The noise limiter (DNR).

• The contrast improvement.

All these functions are integrated in one IC: SAA4978H, 160 pins QFP

ADC/DAC

Analogue to Digital conversion is done with three identical 9-bit ADC's. Digital to Analogue conversion uses three identical 10-bit DAC's. In the PICNIC there are three 9 bits ADCs present for Y,U,V. For digitising the Y (luminance) 9 bits are used, to realise a more detailed picture. The 9 bits are only internally used. Via dithering the 9 bits are reduced to 8 bits and that data is stored into the memory. The data in the memory is fed back to the PICNIC and via undithering the data is again reproduced 9 bits for processing. U/V (colour difference signals) is also sampled with 9 bits. These two 9 bit data streams are multiplexed to 4 bits data streams. This reduction can be allowed, as the perception for colours by the human eye is less sensitive as for luminance.

100 Hz conversion

The main task of the PICNIC is the conversion from 50Hz to 100Hz for YUV and HV-sync. In order to remove 'large area flicker' (especially visible in a white picture), the field-rate of the video is doubled by the FBX6. A 50/60 Hz frame frequency is converted to 100/120 Hz. Also the line frequency (16 kHz) is doubled (32 kHz). Basically, when the video input contains fields A, B etc..., the conversion provides an AABB sequence on the display. The actual conversion is done in the first Field Memory by reading it twice at double speed, while writing it once.

To the PICNIC external IC's are connected dependent of the features. If EM2E has only 100Hz then only one memory-IC is used to store one frame. For sets with Digital Scan the PROZONIC (IC7708, SAA4990H) has been added with two memory-ICs (IC7714/

7715). It is an abbreviation for PROgressive scan Zoom and Noise reduction IC. When applying this, the 2nd Field Memory has to be installed. The following functions are available:

• Line flicker reduction (Digital Scan): this is a feature to reduce the 25 Hz interlace line flicker.

• Dynamic Noise Reduction: noise affected signals can be improved by combining the pixel values of the current and past video fields. This is however only possible in areas without movement.

• Variable Vertical Sample Rate Conversion

• Synchronous No Parity Eight bit Reception an

Transmission interface (SNERT-bus)

Depending on the chassis model, the FBX6 can have the following specification:

Dual Screen compression

The PICNIC can provide horizontal video compression up to 50 %. The compress mode can be used to display dual screens for instance with Teletext (only for widescreen sets).

Panorama

To fit 4:3 pictures into a 16:9 display, a panoramic horizontal distortion can be applied to make a screen-fitting picture without having black sidebars or lost video.

The centre horizontal gain is programmable and the side gain is automatically adapted to make a screen-fit.

Automatic Aspect Ratio Adaptation (AARA)

This feature uses data from the 'black bar detection circuit' to adapt the vertical and horizontal amplitude to an aspect ratio belonging to the display without showing the black bars.

CTI

At CVBS video signals, the bandwidth of colour signals is limited to 1/4 of the luminance bandwidth. Transients between areas of different colours are therefore not very sharp. The PICNIC can steepen these transients artificially with a time manipulation algorithm.

Dynamic Contrast

To make the contrast (black/white) range wider, Philips has invented Dynamic Contrast. It uses the digital memory used in 100 Hz sets. It measures every A-field (25x/s) and digitally analyses where on the greyscale most of the image is located. If it's a relatively dark image, the lighter part of that image is stretched towards white, so that more contrast will become visible in that picture. If it's a relatively light image, the darker part of that image is stretched towards black, so that these darker parts will have more contrast. When the image is in the middle of the greyscale, both dark and light parts are stretched.

9.1.8 Video: High-end Output Processor (HOP, diagram B4)

General

In the HOP (High-end Output Processor, TDA9330) the video processor and digital deflection processor are integrated. The main functions of the HOP are:

• Video control (contrast, brightness, saturation, etc.).

• 2nd RGB interface for OSD/TXT.

• Peak White Limiting.

• Cut-off control and White Drive (RGB outputs).

• Geometry control.

The YUV-signals from the PICNIC are fed to the HOP. In the HOP, the video and geometry control parts are integrated. Also the RGB-signals from TXT/OSD are inserted via the HOP. This IC has all functions from a video processor and geometry control (like the DDP in MD2). The geometry part delivers the H-drive, EW-drive and also a drive signal for rotation. The internal V-drive circuit of the HOP is not used (is explained further on).

Video Control

After conversion to RGB again, the signals can be controlled for Saturation, Contrast and Brightness.

2nd RGB interface for OSD/TXT

On pins 35 - 38 the RGB and fast blanking from the OTC (OSD and TXT) are inserted.

Peak White Limiting

On pin 43 there is a Peak White Limiting signal line (PWL). If the beam current (EHT-info line) increases, then the EHT-info voltage will decrease. PWL is controlled by average limiting via R3343/C2333.

Cut-off control

Switching the TV to Standby:

1. Vertical scan is completed.

2. Vertical flyback is completed (the horizontal output is gated with the flyback pulse, so that the horizontal output transistor cannot be switched on during the flyback pulse).

3. Slow stop of the horizontal output is started, by gradually reducing the 'on' time at the horizontal output from nominal to zero (this will take 50 ms).

Page 47

Circuit descriptions and abbreviation list

4. At the same time the fixed beam current is forced via the black current loop for 25 ms. This is done by setting the RGB outputs to a maximum voltage of 5.6V.

In the EM2E a 'one-point' cut-off control is used: A current of 8 µA (for cut-off) is fed to pin 44 of the HOP. This is done with a measurement pulse during the frame flyback. During the 1st frame, 3 pulses are generated to adjust the cutoff voltage at a current of 8 µA.With this measurement the black level at the RGB-outputs is adjusted. So at start-up there is no monitor pulse anymore. At start-up, the HOP measures the pulses which come back via pin 44. The RGB-outputs have to be between 1.5 V and 3.5 V. If one of the outputs is higher than

3.5 V or one of them lower then 1.5 V, the RGB-outputs will be

blanked.

Geometry control

All geometry control is done via I NVM (IC7011) of the SSB.

Line drive (LINEDRIVE1).

Line drive is derived from an internal VCO of 13.75 MHz. As a reference an external resonator is used (1301). The internal VCO is locked with the HD100-pulse, which comes from the PICNIC. The 'PHI-2' part in the HOP receives the HFB_XRAY_PROT (pin 13) to correct the phase of the line drive. The EHT-info is supplied to pin 14 (DYN-PHASE-CORR) to compensate picture breathing depending on the beam current. Service tip: This is not used at the moment, therefore EHTcompensation in the service menu is put to zero.

C and the data is stored in the

supplies the vertical and horizontal drive pulses and the 100 Hz (2fH) sandcastle pulse.

The VD100 pulse from the PICNIC is only one line long. Therefore this pulse is converted into a VDHOP signal by a 530

s monostable oscillator (extended by 16.5 lines). This signal

is on block function level equal to VSYNC and FRAMEDRIVE+.

The OTC is synchronised on the HD100 pulse from the FBX and on the VSYNC for the synchronisation of TXT/OSD/EPG

When no CVBS is offered to the video processor, the VA and HA pulses are switched off by the HIP, and the VD and HD pulses are then generated by the PICNIC. This to assure a stable OSD.

Frame drive (FRAMEDRIVE+).

The VD100 signal from the PICNIC will be extended for 16.5 lines by the circuit around TS7309 and 7311. The resulting signal (VDHOP) will drive TS7310. This will result in the (asymmetric) FRAMEDRIVE+ signal. Note: The Frame outputs (pins 1/2) of the HOP are not used!

East/West drive.

At pin 3 the E/W-drive is available. Pin 4 is a feedback input for the EHT-info and is used to prevent pumping of the picture. EHT varies also dependent of the beam current. For widescreen without load this is 31.5 kV and with load (1.5 mA)

29.5 kV.

Frame rotation (only for 16:9 sets):

For frame rotation a control voltage is used from pin 25 of the HOP. This voltage can vary from 0.4 V till 4 V.

Guarding protections:

• Flash detection:

When a flash occurs, the EHT-info will become negative very fast. Via D6303/D6304/R3316, TS7303 starts to conduct. This makes pin 5 of HOP high. When pin 5 of HOP is high, then the output (pin 8) is immediately stopped. If H-drive stops then also pin 5 will be low again, which will reset the flash detection. A bit (FLS) will be set in an output status register, so via the OTC it can be seen when there was a flash. This FLS-bit will be reset when the OTC has read that register.

• HFB protection:

If the HFB is not present then this detected via the HOP. The OTC puts the TV into protection and reads a register in the HOP. An error code will be generated.

9.1.9 Synchronisation (diagram B3 & B4)

The HIP video processor provides vertical and horizontal sync pulses VA and HA that are synchronised with the incoming CVBS signal. These pulses are fed to the PICNIC where they are doubled to be synchronous with the 100 Hz picture. The outgoing pulses, VD100 and HD100 are fed to the HOP that

The HOP (located on the SSB) generates the line-drive pulses (LINEDRIVE1), which have a frequency of 31250 Hz (T = 32

s).

When the LINEDRIVE1 signal is high, TS7409 and TS7408 will conduct. A constant DC voltage will be applied across L5410, causing a linear increasing current through this coil. The secondary voltage of L5410 has a negative polarity so that TS7421 will block. When switching on the set, the current through L5410 is supplied by the 5V2 Standby supply (via D6407), and taken over by the +11D voltage (via D6408) of the main supply.

When the LINEDRIVE1 signal becomes low, TS7409 and TS7408 will block. The voltage polarity across the primary winding of L5410 will invert. The positive voltage on the secondary winding will now drive TS7421 into conductivity. Because of the storage time of the line transistor (TS7421), L5410 cannot transfer its energy immediately to the secondary side. This may result in high voltage peaks on the collector of TS7409 and TS7408. To prevent that these peaks will damage the transistors, a 'snubber' circuit (C2414, C2412 and R3411) will suppress them.

When the LINEDRIVE1 signal is high again, the abovedescribed sequence starts again. Circuit L5411 and R3409 will increase the switch-off time of the line transistor.

Operation of the line output stage

To explain the operation of the line output stage, we use the following start conditions:

• TS7421 is driven into conductivity.

GB 87EM2E 9.

Period t1 - t2: When TS7421 is driven into conductivity, the capacitor voltage of 141 V, will be divided across bridgecoil L5422 and the deflection coil (conn. 0317). Due to the chosen inductance values, there will be 100 V across the deflection coil and 41 V across L5422. The linear increasing current in the deflection coil will result in a spot moving from the centre of the picture tube to the right. The voltage across L5422 will also charge C2421 (41 V - 0.7 V).

Period t2 - t3: At the moment the LINEDRIVE signal becomes high, TS7421 will stop conducting. In the coils a voltage will be induced, trying to maintain the current. The current through the line deflection coils continues to flow through C2425 and C2421 and the current through L5422 continues to flow through C2426 and C2421. The energy stored in the line deflection coil is passed to C2425, and the energy of L5422 to C2426. The resonance-frequencies of these 2 LC-circuits define the flyback time of the spot from the right side of the picture tube to the left. On average no current flows through C2421 and thus the voltage across this capacitor remains constant.

Period t3 - t4: As for the period t2 - t3; but now the current flows in the opposite direction, since the voltage across C2425 and C2426 is higher than the voltage across C2433 and C2421.

Period t4 - t5: The coils want to maintain the negative current and will charge the capacitors negative. Because of this, D6422 and D6423 will conduct. The voltage is 100 V across the deflection coil and 41 V across L5422. As both diodes conduct, we may consider the voltage to be constant. A linear current flows with the same changing characteristics as in period t1 - t2. The spot now moves from the extreme left of the picture tube to the centre. Before the current becomes zero, and the spot is located in the centre of the frame, TS7421 reverts back into conductivity. First a short negative current will flow. The cycle starts again.

The linearity correction

A constant voltage across the horizontal deflection coil should result in a linear increasing saw-tooth current. This however is not the case as the resistance of the coil is not negligible. In order to compensate for this, a pre-magnetised coil L5421 in series with the deflection coil is used. This coil ensures that during time interval t1 - t3 the circuit-resistance will be higher than during t4 - t5. L5421 is called the linearity coil. To avoid self-oscillation, R3431 and C2431 are placed parallel to L5421.

The S-correction

Since the sides of the picture are further away from the point of deflection than the centre, a linear saw-tooth current would result in a non-linear image (the centre would be scanned

slower than the sides). To solve this, the deflection current for the right- and left side will be reduced. C2433 is charged quadratic during time interval t1 - t2. Left and right the voltage across the deflection coil decreases, causing the deflection to slow down. In the centre, the voltage increases and the deflection will be faster. An S-shaped current will have to be superimposed onto the saw-tooth current. This correction is called finger-length correction or S-correction. C2433 is relatively small, as a result of which the saw-tooth current will generate a parabolic voltage with negative voltage peaks.. The current also results in a parabolic voltage across C2421, resulting in the finger-length correction, proportionally increasing with the picture width. The EW-DRIVE signal will ensure the largest picture width in the centre of the frame. Here the largest correction is applied. The larger the picture width, the higher the deflection current through C2433.

The E/W-correction

A line, written at the upper- or lower side of the screen, will be larger at the screen centre when a fixed deflection current is used. Therefore the amplitude of the deflection current must be increased when the spot approaches the screen centre. This is called East/West correction. The EW-DRIVE signal is generated in the HOP and will drive FET TS7480 via TS7481 and optocoupler TS7482. TS7480 will charge capacitor C2423 more or less, increasing the deflection

Secondary line-voltages

During the blocking time of TS7421, the magnetic energy of coil 1 - 5 of the LOT will be transferred to electrical energy in the secondary winding. Via rectifying and smoothing, the several secondary supply voltages will be generated:

• EHT, Focus and Vg2-voltage

• +180V for the CRT panel (pin 8 LOT)

• +11D for the line deflection (pin 12 LOT)

• +13VLOT for the frame deflection (pin 6 LOT)

• -15VLOT for the frame deflection (pin 3 LOT)

• Filament voltage (pin 9 LOT)

The EHT-INFO signal is derived via R3450//R3451. This signal decreases while the beam current increases. It is fed to the HOP to compensate for loss of picture width and picture height.

The DYN-FASE-CORR signal is fed to the HOP via C2455 and drives a dynamic phase correction necessary because of beam current variations. This is done by regulating T transistor TS7421.

of the line

East-West circuit

The moment TS7480 is driven into saturation, C2421 will discharge during the flyback. As a consequence of which C2421 must be charged again during the scan via the conduction diode D6422 (as long as C2421 is not charged to the voltage across L5422, D6422 will conduct). The current in the deflection coil is therefore larger than the current flowing in L5422 (1-2). The voltage across the deflection coil increases, so the picture width increases. When TS7480 blocks, C2421 will not discharge anymore and the voltage across C2421 will remain constant. The result is that the voltage across the deflection coil is minimal. The voltage across coil L5422, however, is maximal. This coil (L5422) consists of a transformer:

• As the current through the coil 1-2 increases (smaller picture width), the current through coil 3-4 decreases. Because of the transformer characteristic a higher voltage will be subjected to coil 3-4, which will counteract the current. The current will diminish even further.

• When the current through coil 1-2 diminishes (larger picture width), the current through coil 3-4 increases.

The EW Drive

The EW drive signal originates in the HOP and is supplied to TS7480. The shape of this signal determines the various geometric correction parameters:

• H amplitude

• EW-parabola

• EW-corner

• EW-trapezium

• Horizontal parallelogram

• Horizontal bow

Beam current correction

The EHT-info at point 10 of the LOT is dependent on the value of the beam current and the voltage divider R3450, R3451 and C2450. The EHT-info is fed to the HOP to trim the contrast and to compensate for the changes in picture-width as a function of the EHT-info, when the high-voltage is decreased. The EHTinfo is integrated via C2450 and sent to the gate of the E/W FET (TS7480) as a DC-voltage to correct the EW-current.

The HOP drives the frame output stage. As the HOP is 'cold' and the frame output stage is 'hot', they must be galvanic isolated by means of an optocoupler. In the MG-chassis the HOP generates 3 signals needed for the frame output stage: VDPOS, VDNEG and FRAME ROTATION. To avoid the costs of 3 optocouplers, the frame drive pulse and rotation DCvoltage are added together and then fed to optocoupler TS7610.

This is done as follows: The VD100 signal from the PICNIC (diagram B3 pin 19) is extended for 16.5 lines and inverted via a monostable multivibrator (TS7311 & TS7309, diagram B4). The output signal VDHOP is then superimposed on a DCvoltage from pin 25 of the HOP. The resulting signal is called FRAMEDRIVE+ and is fed to optocoupler 7610 (diagram A4). So this signal contains info for both the frame deflection and the frame rotation.

The circuit around IC7440 will amplify this signal and the output current will flow through the rotation coil. The vertical pulses on this signal are filtered by C2445 to ensure that only a DCvoltage will be supplied to the rotation coil. The output voltage of the rotation circuit is between -8 and +8 V.

Flyback generator

The frame output stage is supplied via the +13 V and -15 V coming from the LOT. The output of the amplifier is 0 V

, so

a coupling capacitor is not required.

CL 96532156_026.eps

210100

During the (forward) scan, a supply of +13 and -15 V is sufficient to respond to the slow changing current. The flyback generator puts a voltage of -15 V on pin 3. Because of the voltage drop over zenerdiode D6622 (8.2 V), C2622 will be charged to 19 V: being 13 + (15 - 8.2 - 0.7) V. During the flyback scan, the change in current per time is much larger, so a higher voltage is required. The flyback generator will now generate a voltage of +13 V on pin 3. Added to the charge on C2622 this will give a flyback voltage of 32 V (depending on the CRT size, this value can differ).

The IC amplifier (IC7620, pin 5) supplies the sawtooth current to the frame deflection coil. The current through this coil is measured via R3620//R3621//R3622 and fed back to the inverting input of the amplifier. R3624 and C2624 on the output of the amplifier, form a filter for high frequencies and in that way also prevents oscillations. Peak voltages on the output, e.g. as a result of a possible flash, are damped by the clamp circuit consisting of D6619, C2627 and R3627. The network consisting of R3625, R3629 and C2629 form an extra damping circuit.

Protection circuit for bridge-coil and frame output stage

The secondary voltage of bridge coil L5422 is guarded at the diode modulator (D6421/22) via a detection circuit consisting of an 8.2 V zenerdiode (diagram A3). When the bridge-coil is working properly, the average voltage on D6422 is such that this zenerdiode will conduct and will drive TS7652 into saturation via the BRIDGE_PROT signal (see diagram A4). When, for any reason, the secondary side of the bridge-coil is shorted, the average voltage on D6422 will drop below the zener-voltage and TS7652 will block. Now capacitor C2642 will be charged. Transistor TS7407 will start conducting and the STANDBY signal will be grounded via R3403. This will switch off the main supply (see diagram A1).

Page 51

Circuit descriptions and abbreviation list

GB 89EM2E 9.

Via the circuit built around TS7641 the frame output stage is guarded. If the frame output stage is working properly, TS7641 and TS7652 will both conduct and thereby discharging C2642. TS7407 is blocked now, causing the STANDBY signal to be high-ohmic. If there are frame pulses missing, TS7641 will block and capacitor C2642 can be charged. Transistor TS7407 will now start conducting and the STANDBY signal will be grounded via R3403. This will switch off the main supply (see diagram A1).

9.1.12 Audio (diagram B6, A5 & A6)

Introduction

All EM2E sets contain one of ITT's Multistandard Sound Processing IC's for sound decoding. The diversity arises because each member of the MSP-family handles its own set of sound standards:

• MSP3415D: Europe & AP decoding, Stereo incl. NICAM.

• MSP3451G: Global decoding, Virtual Dolby.

This IC takes care of the main FM sound decoding. AM decoding for the L system is done by the HIP. The demodulated L sound is then again source selected and processed in the MSP. The reason for this is the bad AM detection performance of the MSP. In case of NICAM L however, this is handled by the MSP.

All MSP versions contain digital audio processing, used for the basic left/right stereo sound, such as bass, treble, balance, incredible sound and spatial. In addition to that, the MSP3451 is also able to perform Virtual Dolby, a Dolby approved sound mode for surround sound reproduction with left/right speakers only.

Audio source selection

• MSP3515D (stereo)

This IC is an economised version of the MSP3410 that is used in the MG-chassis. It can cover 2 stereo and 1 mono (AM) input. Since more inputs are required, a separate source selector is used (HEF4052, IC7675). This selector has EXT1, EXT2, FRONT and SC1-OUT (Tuner) as input and is connected to the SCART1 input of the MSP3415. The SCART2 input is not used.

Since the MSP3415 has only one SCART output, which is connected to the SCART1, a constant level output and connection to SCART2 is not available. This is fixed by connecting the HEF4052 input selector to the constant level output and to SCART2 via a so-called 'Régimbeau' switch (IC7652). This switch is needed to prevent feedback (Larsen effect). When EXT2 is chosen as input signal, and the output of SCART2 is selected, this means that the main picture is also EXT2 and will cause the Larsen effect. To prevent this, the record select must be switched to Tuner. This is especially important when decoders are used, behind a 'transparent' VCR connected to EXT2.

To get a constant level output if the Tuner is selected, the SCART1 output (Tuner at any time), has to be fed back to the input selector and selected as input for the MSP (SCART1 input).

The MSP3415 has no separate output to drive a headphone. The headphone is therefore hardwired (on the LSP) to the main sound output.

• MSP3451G (Virtual Dolby)

The MSP3451, which is used in all versions supporting Virtual Dolby, is capable of supporting 4 stereo inputs and 1 mono

(AM) INPUT. Therefore the extra input selector (HEF4052) is not needed.

The MSP3451 is also capable of supporting 2 SCART outputs, so the trick used in the MSP3415 set-up to get a constant level output is not needed.

The MSP3451 has a separate headphone output, so sound control be done separate from the speakers.

Audio decoding

At the input a choice can be made between two IF-signals; SIF and SIFM. The selected signal is fed to the AGC. After this, an ADC converts the IF-signal to digital.

This digital signal can be processed by 2 demodulation channels. The first one is able to handle FM and NICAM signals. The second one can handle FM and AM signals.

Each channel contains a mixer to shift the incoming signal in the frequency domain. This shift is determined by the value of a DCO.

After the down-mix, the signal is fed, via a filter, to a discriminator. From here the AM, FM or NICAM demodulation can be performed.

Both channels contain an 'automatic carrier mute' function, which automatically mutes the output of the analogue section when no carrier is detected.

After demodulation, the FM-signals are subjected to a deemphasis operation. After that the matrix of the stereo system is applied.

Audio processing

The sound processing in EM2E is completely done by the MSP3415D for 'Stereo' sets or the MSP3451G for 'Virtual Dolby' sets:

• Volume control is done by the user via the SOUND menu.

• Tone control in 'Stereo' sets is done via the BASS/TREBLE

control, in 'Virtual Dolby' sets via the 5-band equaliser.

• Headphone control in 'Stereo'-sets is done via the loudspeaker output of the MSP, no sound control possible. In 'Virtual Dolby'-sets, the MSP has a separate Headphone output so separate sound control is possible.

• Mute control can be done in different ways: – Via the SOUND_ENABLE line of the OTC. Used during

start-up/switch-off conditions, in order to avoid audible plops.

– Via the decoding part of the MSP. – Via the processing part of the MSP.

The mute on the RC or in the UI is per today a combination of processing mute and SOUND_ENABLE line. When a user mute is done, the processing mute will turn down the volume, after which the SOUND_ENABLE line is switched. De-muting is the other way around. The reasons for this is a technical problem with crosstalk of the headphone into the loudspeakers.

Automatic Volume Levelling (AVL)

One of the features of the MSP-family is AVL. If used, it limits the big volume differences in the broadcast between e.g. news transmissions and commercials or within a movie. To be able to get a Dolby approval (for the Virtual Dolby sets), the AVL feature must be switchable. Therefore, the AVL feature is customer switchable via the menu.

Audio amplification

The audio amplifier part is very straight forward. It uses an integrated power amplifier IC, the TDA2616. It delivers an

Page 52

Circuit descriptions and abbreviation list

output of 2 x 10 WRMS to 2 full range speakers. A subwoofer is not implemented.

The supply voltage is +28 V, generated by the main supply via L5506.

Muting is done via the SOUND-ENABLE line connected to pin 2 of the amplifier-IC and coming from the OTC. This signal is inverted by TS7730, as a result of which at a high level of the SOUND-ENABLE signal, current is sinked from pin 2 and the IC mutes.

9.1.13 Teletext / NexTView (diagram B5)

Teletext

The TXT-decoder in the OTC gets its video signal directly on pin 5 (from the HIP). The RGB-outputs are available on pins 77/78/79. Fast blanking is realised via pen 80. In the previous chassis there was separate memory to store the TXT information. In EM2E the DRAM (IC7007) of the microprocessor is also used for the TXT-decoder.

NexTView

NexTView allows the user to display a program guide on the TV screen that contains extensive information for each program.

This information can be displayed in a number of different summaries:

• DAY: The daily summary shows, from the current moment, the program schedule for several stations for a short time ahead.

• CHANNEL: The channel summary shows the program schedule for one station.

• THEME: The theme summary shows, for each theme, the program schedule of the various stations. These themes consist of sport, film, culture, etc. and is determined from the station side.

NexTView does not have to restrict itself to information about the station that is being viewed, but also offers information about other stations. In the various summaries 3 different commands can be given for the various program overviews. These commands appear as follows:

• WATCH: The set immediately switches over to the station concerned.

• REMINDER: The start time and date and the station of the program concerned is stored in the TV reminder list. The TV will give an OSD-message with the program information, or switch on the set at the correct moment (provided the set is in Standby) and tune to the station concerned.

• RECORD: The timer of the video recorder with ‘Easylink Plus’ is programmed with the data of the program concerned. There has to be a video recorder (with Easylink Plus) connected to SCART2 otherwise the ‘RECORD’ function will not be highlighted. The connection is via pin 10 from SCART. This means that it has to be a full SCART or at least pin 10 has to be wired.

In order to be able to realise NexTView, two teletext type data flows, Data stream 1 and 2, are transmitted with various subcode pages of information. This data flow can transport limited information (max. 40 pages). Data stream 1 is quick repeating with a repetition time of approximately 20 to 30 seconds. However, Data stream 2 has a much longer repetition time of approximately half an hour and has a large transport capacity.

• Data stream 1 contains information of the station that is being viewed.

• Data stream 2 contains up to one week of advance information from various stations that are covered by the provider.

9.1.14 CRT / SCAVEM / Rotation (diagram F)

RGB amplifiers

On the CRT panel, the RGB amplifier (TDA6108, IC7307) is located. Via the outputs 9, 8 and 7 the cathodes of the picture tube are driven. The supply voltage for the amplifier is 180 V and is derived from the LOT.

SCAVEM

The SCAVEM-circuitry is implemented in the layout of the picture tube panel. It is thus not an extra module. SCAVEM means SCAn VElocity Modulation. This means that the horizontal deflection is influenced by the picture content. In an ideal square wave, the sides are limited in slope by a limited bandwidth (5 MHz). SCAVEM will improve the slope as follows: At a positive slope, a SCAVEM-current is generated which supports the deflection current. The first half of the slope the spot is accelerated and the picture is darker, while at the second half of the slope, the spot is delayed and the slope becomes steeper. At the end of the slope, the SCAVEM-current decays to zero and the spot is at the original position. An overshoot occurs which improves the impression of sharpness. At the negative slope, the SCAVEM-current counteracts the deflection. During the first half of the slope, the spot is delayed, the slope becomes steeper. During the second half the spot accelerates, the SCAVEMcurrent is zero at the end of the slope.

Via the three resistors R33315, R33317 and R3320, Red, Green and Blue are added together and offered to the emitter TS7300. On the collector of this transistor, configured in a common base, the sum of these 3 signals is obtained. Via the emitter follower formed with TS7301, this signal is conveyed to the differentiator C2303, R3309 and R3318. Only the high frequencies are differentiated (small RC-time). The positive and negative pulses of this signal drive respectively TS7303 and TS7302 into conductivity. The DC setting of the output stage is set by R3304, R3308, R3316 and R3319. The working voltage of the transistors is settled at half the supply voltage. At the positive section of the pulse, the current flows through R3318, C2307, the SCAVEM-coil and TS7303. At the negative section of the pulse, the current flows through R3318, C2409, the SCAVEM-coil and TS7302.

Rotation

In sets with a rotation coil (widescreen sets ≥ 32"), the amount of frame rotation is adjusted with the DAC-output of the HOP (see also 'Vertical Deflection').

9.1.15 Software related features

Following features are described:

• Smart Local Doming Prevention (SLDP)

• Auto TV

• Switch ON behaviour

Smart Local Doming Prevention (SLDP)

A CRT with an iron shadow mask shows a considerable amount of local doming (due to local heating), resulting in unwanted colour artefacts. SLDP helps to reduce these artefacts for both 16:9 and 4:3 sets to an acceptable level. It measures the beam current in areas that are sensitive to local doming and reduces the contrast if the beam current in these places exceeds a pre-set threshold. The chosen solution in EM2E, is based on the PICNIC hardware and software and it uses the histogram measurement of the PICNIC to make a prediction of the local heating of the CRT shadow mask.

GB 91EM2E 9.

With SLDP, local doming is diminished to an acceptable level at the cost of contrast reduction. By using a 'smart' solution for a part of the necessary contrast reduction, the resulting picture remains even more acceptable. SLDP is not a feature. It’s an algorithm that diminishes local doming effects. These effects occur whenever iron mask ( and in a limited way invar mask) tubes are applied. Therefore, there is no reason to make it switchable for the customer. However, SLDP can be switched off via the Service Alignment Mode (SAM).

AutoTV

The AutoTV (or 'Automatic Picture Control' or 'Active Control') aims at giving the customer the best possible picture performance at any time. Therefor it does real time processing of the video signal and as a result, it decides to adapt several video parameters throughout the whole chassis.

The AutoTV feature integrates traditional picture performance, AutoTV functionality and 'smart controls' in order to come to a kind of 'supersmart' TV. It can be subdivided in:

• Auto Noise Reduction. This algorithm measures the amount of noise in the incoming video signal (this is done by the LIMERIC part of the PICNIC). As a result of this measurement, the amount of noise in the picture is corrected, starting from that noise level which is annoying for the customer. Which parameters exactly can be used is depending on the hardware.

• Auto Sharpness. This algorithm measures the amount of sharpness via the bandwidth of the incoming video signal and adapts the peaking frequency in the PICNIC according to this info. If the 'sharpness meter' sees the video content as 'sharp', high frequency peaking will be used. On the other hand, if the picture content is seen as 'not sharp', a low/mid frequency peaking is used. There is a coupling between the Auto Noise and the Auto Sharpness algorithm: if noise is present in the video content, then in general the sharpness will be made less aggressive. Special care has to be taken to the interaction of the LIMERIC and the vertical peaking of the PICNIC: a too big amount of vertical peaking increases the visibility of the 2DNR artefacts.

In the EM2E a limited AutoTV control function is used: only a combination of above described features is used in the background in order to improve the set performance, specially focussed on noise reduction.

between each polling approx. 5 ms). If this detection still fails after 1 second, an error should be generated and the set must be switched to protection (error: “+8 V).

After detection of the +8 V, the MSP must be reset, since it can

disturb I on, I

C traffic when not properly reset. From this moment

C traffic is possible.

To be sure that the HOP is properly started up, the POR bit of the HOP should be read. If this is not successful, the Standby info has to be put high again and an error code (code 11: HOP) will be generated. If the reading of the POR bit is successful, the starting procedure can be continued.

The Standby info line must be switched high again. The sync mode and the black current stabilisation loop of the HOP must be disabled in order to have a smooth start-up. Within 23.5 ms after reading the HOP POR bit, the HOP has to be started up via the HOP_start commando. If this condition is not fulfilled, the HOP will stop his line drive again and the set will not be able to start up.

During start-up of the deflection, I 250 ms to avoid data corruption. If flashes or spikes are generated during EHT start-up, I

C traffic must be disabled for

C data could be disturbed or

corrupted.

After deflection is powered up completely, all protection algorithms are set active. The rest of the NVM content can now be read and the IC’s can be initialised according this info.

If SLDP is present in the set, an initialisation of SLDP has to be performed, including a calibration of the beamcurrent ADC.

The sync-mode of the HOP must be switched to active and the black current stabilisation loop in the HOP is switched on. Some extra checking is done to ensure that the loops are completely stabilised. Software sets all the necessary parameters for a correct sound and image and unblanks the picture.

A provision is foreseen to avoid sets in the field that will never unblank, if the picture tube is severely worn out. If the black current stabilisation does not become stable within a time frame of 30 seconds, the picture is unblanked anyway

Switch ON behaviour

First of all, the microprocessor needs to start up: After the power is applied, the 'Standby supply' starts oscillating, generating the +5V2 and +3V3. When ready, a reset (POR) is generated and the OTC is awakened.

During reset, the OTC puts a high level on all his outputs, causing the degaussing relay to close. After the reset, the outputs and inputs of the OTC must be initialised to their default state. The degaussing output of the OTC must stay high for 12 seconds.

Next step is the check whether the set needs to be in Standby or not. Therefore, the NVM content is read and the Standby-bit is checked. If the set is to stay in Standby, there is no further action.

If the set has to be switched 'on', the Standby-info line is pulled low. This results in the low power mode start-up of the HOP. The line drive starts to run on 50 kHz, wakes up the main supply and the +5 V, +8 V and +141 V supplies become available. The OTC waits until the +8 V is fully present. This is done by checking the ADC input of the OTC. A positive result means three times a positive +8 V detection in a row (time
