2.1 Safety Instructions For Repairs

2.2 Maintenance Instructions

2.3 Warnings

2.4 Notes

2.1 Safety Instructions For Repairs

Safety regulations require that during a repair:

• Due to the ‘hot’ parts of this chassis, the set must be connected to the AC power via an isolation 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. Pay particular attention to the following points:

• General repair instruction: as a strict precaution, we advise you to re-solder the solder connections 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 re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years old.

• Route the wire trees and EHT cable correctly and secure them with the mounted cable clamps.

• Check the insulation of the AC power cord for external damage.

• Check the strain relief of the AC power cord for proper function, to prevent the cord from touching the CRT, hot components, or heat sinks.

• Check the electrical DC resistance between the AC plug and the secondary side (only for sets that have an isolated power supply). Do this as follows:

1. Unplug the AC power cord and connect a wire between

the two pins of the AC plug.

2. Turn on the main power switch (keep the AC power

cord unplugged!).

3. Measure the resistance value between the pins of the

AC plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 MΩ and 12 MΩ.

4. Switch the TV OFF and remove the wire between the

two pins of the AC plug.

• Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.

2.2 Maintenance Instructions

It is recommended to have a maintenance inspection carried out by qualified service personnel. 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 three to five years.

• When the set is used in an environment with higher dust, grease or moisture levels, for example in a kitchen, the recommended interval is one year.

• The maintenance inspection includes the following actions:

1. Perform the 'general repair instruction' noted above.

2. Clean the power supply and deflection circuitry on the

chassis.

3. Clean the picture tube panel and the neck of the picture tube.

2.3 Warnings

• In order to prevent damage to ICs and transistors, avoid all high voltage flashovers. In order to prevent damage to the picture tube, use the method shown in Fig. 2-1, to discharge the picture tube. Use a high voltage probe and a multi-meter (position VDC). Discharge until the meter reading is 0 V (after approx. 30 s).

CL 26532098/042

Figure 2-1

• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD) w. 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 potential. Available ESD protection equipment: – Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable, and ground cable) 4822 310 10671.

– Wristband tester 4822 344 13999.

• Together with the deflection unit and any multi-pole unit, flat square picture tubes form an integrated unit. The deflection and the multi-pole 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 you align the set, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable.

2.4 Notes

2.4.1 General

• Measure the voltages and waveforms with regard to the chassis (= tuner) ground (H), or hot ground (I), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them 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 for PAL, or

61.25 MHz for NTSC (channel 3).

• Where necessary, measure the waveforms and voltages with (D) and without (E) aerial signal. Measure the voltages in the power supply section both in normal operation (G) and in stand-by (F). These values are indicated by means of the appropriate symbols.

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

Safety Instructions, Warnings, and Notes

EN 5L01.2A AB 2.

2.4.2 Schematic Notes

• All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kohm).

• Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm).

• All capacitor values are given in micro-farads (µ= x10 nano-farads (n= x10

• Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).

• An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values.

• The correct component values are listed in the Spare Parts List. Therefore, always check this list when there is any doubt.

2.4.3 Rework on BGA (Ball Grid Array) ICs

General

Although (LF)BGA assembly yields are very high, there may still be a requirement for component rework. By rework, we mean the process of removing the component from the PWB and replacing it with a new component. If an (LF)BGA is removed from a PWB, the solder balls of the component are deformed drastically so the removed (LF)BGA has to be discarded.

Device Removal

As is the case with any component that, it is essential when removing an (LF)BGA, the board, tracks, solder lands, or surrounding components are not damaged. To remove an (LF)BGA, the board must be uniformly heated to a temperature close to the reflow soldering temperature. A uniform temperature reduces the chance of warping the PWB. To do this, we recommend that the board is heated until it is certain that all the joints are molten. Then carefully pull the component off the board with a vacuum nozzle. For the appropriate temperature profiles, see the IC data sheet.

Area Preparation

When the component has been removed, the vacant IC area must be cleaned before replacing the (LF)BGA. Removing an IC often leaves varying amounts of solder on the mounting lands. This excessive solder can be removed with either a solder sucker or solder wick. The remaining flux can be removed with a brush and cleaning agent. After the board is properly cleaned and inspected, apply flux on the solder lands and on the connection balls of the (LF)BGA. Note: Do not apply solder paste, as this has shown to result in problems during re-soldering.

Device Replacement

The last step in the repair process is to solder the new component on the board. Ideally, the (LF)BGA should be aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers. To reflow the solder, apply a temperature profile according to the IC data sheet. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times.

1.1.2005 onwards.

),

).

Figure 2-2 Lead-free logo

This sign normally has a diameter of 6 mm, but if there is less space on a board also 3 mm is possible.

Regardless of this logo (is not always present), one must treat all sets from this date onwards according to the following rules.

Due to lead-free technology some rules have to be respected by the workshop during a repair:

• Use only lead-free soldering tin Philips SAC305 with order code 0622 149 00106. If lead-free solder paste is required, please contact the manufacturer of your soldering equipment. In general, use of solder paste within workshops should be avoided because paste is not easy to store and to handle.

• Use only adequate solder tools applicable for lead-free soldering tin. The solder tool must be able – To reach at least a solder-tip temperature of 400°C. – To stabilise the adjusted temperature at the solder-tip. – To exchange solder-tips for different applications.

• Adjust your solder tool so that a temperature around 360°C

- 380°C is reached and stabilised at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400°C, otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed. To avoid wear-out of tips, switch “off” unused equipment or reduce heat.

• Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If not to avoid, clean carefully the solder-joint from old tin and re-solder with new tin.

• Use only original spare-parts listed in the Service-Manuals. Not listed standard material (commodities) has to be purchased at external companies.

• Special information for lead-free BGA ICs: these ICs will be delivered in so-called "dry-packaging" to protect the IC against moisture. This packaging may only be opened short before it is used (soldered). Otherwise the body of the IC gets "wet" inside and during the heating time the structure of the IC will be destroyed due to high (steam)pressure inside the body. If the packaging was opened before usage, the IC has to be heated up for some hours (around 90°C) for drying (think of ESD-protection!). Do not re-use BGAs at all!

• For sets produced before 1.1.2005, containing leaded soldering tin and components, all needed spare parts will be available till the end of the service period. For the repair of such sets nothing changes.

In case of doubt whether the board is lead-free or not (or with mixed technologies), you can use the following method:

• Always use the highest temperature to solder, when using SAC305 (see also instructions below).

• De-solder thoroughly (clean solder joints to avoid mix of two alloys).

Caution: For BGA-ICs, you must use the correct temperatureprofile, which is coupled to the 12NC. For an overview of these profiles, visit the website www.atyourservice.ce.philips.com (needs subscription, but is not available for all regions)

• Always respect voltages. While some may not be

dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

5.4 ComPair

receive I television. In this way, it is possible for ComPair to communicate (read and write) to devices on the I

2

C commands to the micro controller of the

2

C busses

of the TV-set.

• Manually (by asking questions to you): 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 faultfinding tree by asking you questions (e.g. Does the screen gives a picture? Click on the correct answer: YES / NO) and showing you examples (e.g. Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope). You can answer by clicking on a link (e.g. text or a waveform picture) that will bring you to the next step in the faultfinding process.

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.

Beside fault finding, ComPair provides some additional features like:

• Up- or downloading of pre-sets.

• Managing of pre-set lists.

• Emulation of the (European) Dealer Service Tool (DST).

• If both ComPair and SearchMan (Electronic Service Manual) are installed, all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink.

Example: Measure the DC-voltage on capacitor C2568 (Schematic/Panel) at the Monocarrier.Click on the ‘Panel’

hyperlink to automatically show the PWB with a highlighted capacitor C2568. Click on the ‘Schematic’ hyperlink to automatically show the position of the highlighted capacitor.

5.4.1 Introduction

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

• ComPair helps you to quickly get an understanding on how to repair the chassis in a short time by guiding you systematically 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 because ComPair takes care of this.

• ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available. When ComPair is installed together with the SearchMan electronic manual of the defective chassis, schematics and PWBs are only a mouse click away.

5.4.2 Specifications

ComPair consists of a Windows based faultfinding 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 L01 chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector (located on the Main panel, see also figure 8-1 suffix D).

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

• Automatic (by communication with the television): ComPair can automatically read out the contents of the entire error buffer. Diagnosis is done on I

2

the I

C bus of the television. ComPair can send and

C level. ComPair can access

2

C level) and

2

C commands

5.4.3 How to Connect

1. First install the ComPair Browser software (see the Quick Reference Card for installation instructions).

2. Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ‘PC’) of the ComPair interface.

3. Connect the AC power adapter to the supply connector (marked with ‘POWER 9V DC’) on the ComPair interface.

4. Switch the ComPair interface OFF.

5. Switch the television set OFF (remove the AC power).

6. Connect the ComPair interface cable between the connector on the rear side of the ComPair interface (marked with ‘I

2

C’) and the ComPair connector on the

mono carrier (see figure 8-1 suffix D).

7. Plug the AC power adapter in the AC power outlet and switch on the interface. The green and red LEDs light up together. The red LED extinguishes after approx. 1 second while the green LED remains lit.

8. Start the ComPair program and read the ‘introduction’ chapter.

• ComPair interface cable: 3122 785 90004

5.5 Error Buffer

The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is written at the left side and all other errors shift one position to the right.

5.5.1 How to Read the Error Buffer

Use one of the following methods:

• On screen via the SAM (only if you have a picture).

Examples:

– ERROR: 0 0 0 0 0: No errors detected – ERROR: 6 0 0 0 0: Error code 6 is the last and only

detected error

–ERROR: 9 6 0 0 0: Error code 6 was first detected and

error code 9 is the last detected (newest) error

• Via the blinking LED procedure (when you have no picture). See next paragraph.

•Via ComPair.

5.5.2 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:

• By activation of the CLEAR command in the SAM menu:

• When you exit SDM / SAM with the STANDBY command on the remote control (when leaving SDM / SAM, by disconnecting the set from AC power, the error buffer is not reset).

• When you transmit the command DIAGNOSE-99-OK with ComPair.

• If the content of the error buffer has not changed for 50 hours, it resets automatically.

5.5.3 Error Codes

In case of non-intermittent faults, clear the error buffer before you begin the repair. These to ensure that old error codes are no longer present. If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error code and not the actual cause (e.g., a fault in the protection detection circuitry can also lead to a protection).

Service Modes, Error Codes, and Fault Finding

EN 13L01.2A AB 5.

5.6 The Blinking LED Procedure

Via this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful when there is no picture.

When the SDM is entered, the LED will blink the contents of the error-buffer. Error-codes ≥ 10 are shown as follows: – a long blink of 750 ms (which is an indication of the decimal

digit), – a pause of 1.5 s, – n short blinks (n = 1 - 9), – when all the error-codes are displayed, the sequence

finishes with a LED blink of 3 s, – the sequence starts again.

Example of error buffer: 12 9 6 0 0 After entering SDM: – 1 long blink of 750 ms followed by a pause of 1.5 s, – 2 short blinks followed by a pause of 3 s, – 9 short blinks followed by a pause of 3 s, – 6 short blinks followed by a pause of 3 s, – 1 long blink of 3 s to finish the sequence, – the sequence starts again.

5.7 Protections

time, measure the ‘+8V’. If this voltage is missing, check transistor TS7480.

• Set is non-stop in hiccup mode Set is in over current

mode; check the secondary sensing (opto coupler 7515) and the ‘MainSupply’ voltage. Signal ‘Stdby_con’ must be logic low under normal operation conditions and goes to high (3.3 V) under standby and fault conditions.

• Set turns on, but without picture and sound The screen

shows snow, but OSD and other menus are okay. Blinking LED procedure indicates error 11, so problem is expected in the tuner (pos. 1000). Check presence of supply voltages. As ‘Vlotaux+5V’ at pin 5 and 7 are okay, ‘VT_supply’ at pin 9 is missing. Conclusion: resistor 3460 is defective.

• Set turns on, but with a half screen at the bottom. Sound is okay Blinking LED (set in SDM mode) indicates error 3. Check ‘Vlotaux+13V’ and ‘+50V’. If they are okay, problem is expected in the vertical amplifier IC7471. Measure with a scope the waveform on pin 17 of the UOC. Measure also at pin 1 of IC7471. If here the signal is missing, a defective resistor R3244 causes the problem.

If a fault situation is detected an error code will be generated and if necessary, the set will be put in the protection mode. Blinking of the red LED at a frequency of 3 Hz indicates the protection mode. In some error cases, the microprocessor 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 ComPair. The DST diagnose functionality will force the set into the Service-standby, which is similar to the usual standby mode, however the microprocessor has to remain in normal operation completely.

To get a quick diagnosis the chassis has three 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). Adjustment of the set via a menu and with the help of test patterns.

See for a detailed description Chapter 9 paragraphs Deflection and Power Supply.

5.8 Repair Tips

Below some failure symptoms are given, followed by a repair tip.

• Set is dead and makes hiccuping sound ‘MainSupply’ is available. Hiccuping stops when de-soldering L5561, meaning that problem is in the ‘MainSupply’ line. No output voltages at LOT, no horizontal deflection. Reason: line transistor TS7460 is defective.

• Set is dead, and makes no sound Check power supply IC7520. Result: voltage at pins 1, 3, 4, 5 and 6 are about 180 V and pin 8 is 0 V. The reason why the voltage on these pins is so high is because the output driver (pin 6) has an open load. That is why MOSFET TS7521 is not able to switch. Reason: feedback resistor 3523 is defective. Caution: be careful measuring on the gate of TS7521; circuitry is very high ohmic and can easily be damaged! (first connect measuring equipment to ground, then to the gate).

• Set is in hiccup mode and shuts down after 8 s. Blinking LED (set in SDM mode) indicates error 5. As it is unlikely that µP ‘POR’ and ‘+8V protection’ happen at the same

Index of this chapter:

8.1 General Alignment Conditions

8.2 Hardware Alignments

8.3 Software Alignments and Settings

Note:

• The Service Default Mode (SDM) and Service Alignment Mode (SAM) are described in chapter 5.

• Menu navigation is done with the 'CURSOR UP, DOWN, LEFT or RIGHT' keys of the remote control transmitter.

• Figures can deviate slightly from the actual situation, due to different set executions or software versions.

8.1 General Alignment Conditions

Perform all electrical adjustments under the following conditions:

• AC voltage and frequency: according to country’s standard.

• Connect the set to the AC power via an isolation transformer.

• Allow the set to warm up for approximately 20 minutes.

• Measure the voltages and waveforms in relation to chassis ground (with the exception of the voltages on the primary side of the power supply). Never use the cooling fins / plates as ground.

• Test probe: Ri > 10 MΩ; Ci < 2.5 pF.

•Use an isolated trimmer / screwdriver to perform the alignments.

8.2.1 Vg2 Adjustment

1. Activate the SAM.

2. Go to the WHITE TONE sub menu.

3. Set the values of NORMAL RED, GREEN and BLUE to 40.

4. Go, via the MENU key, to the normal user menu and set – CONTRAST to zero. – BRIGHTNESS to minimum (OSD just visible in a dark

room).

5. Return to the SAM via the MENU key.

6. Connect the RF output of a pattern generator to the antenna input. Test pattern is a 'black' picture (blank screen on CRT without any OSD info).

7. Set the channel of the oscilloscope to 50 V/div and the time base to 0.2 ms (external triggering on the vertical pulse).

8. Ground the scope at the CRT panel and connect a 10:1 probe to one of the cathodes of the picture tube socket (see diagram B).

9. Measure the cut off pulse during first full line after the frame blanking (see Fig. 8-2). You will see two pulses, one being the cut off pulse and the other being the white drive pulse. Choose the one with the lowest value, this is the cut off pulse.

10. Select the cathode with the highest V alignment. Adjust the V

of this gun with the SCREEN

cutoff

value for the

DC

potentiometer (see Fig. 8-1) on the LOT to the correct value (see table below).

11. Restore BRIGHTNESS and CONTRAST to normal (= 31).

3. Adjust the FOCUS potentiometer (see Fig. 8-1) until the vertical lines at 2/3 from east and west, at the height of the centreline, are of minimum width without visible haze.

8.3 Software Alignments and Settings

Enter the Service Alignment Mode (see chapter 5). The SAM menu will now appear on the screen. Select one of the following alignments:

How to change an Option Byte

An Option Byte represents a number of different options. Changing these bytes directly makes it possible to set all options very fast. All options are controlled via seven option bytes. Select the option byte (OB1.. OB7) with the MENU UP/ DOWN keys, and enter the new value.

Leaving the OPTION submenu saves changes in the Option Byte settings. Some changes will only take effect after the set has been switched OFF and ON with the AC power switch (cold start).

How to calculate the value of an Option Byte

Calculate an Option Byte value (OB1 .. OB7) in the following way:

1. Check the status of the single option bits (OP): are they enabled (1) or disabled (0).

2. When an option bit is enabled (1) it represents a certain value (see first column ‘value between brackets’ in first table below). When an option bit is disabled, its value is 0.

3. The total value of an Option Byte is formed by the sum of its eight option bits. See second table below for the correct Option Bytes per typenumber.

9.1 Introduction

The L01 (small screen) chassis is a global TV chassis for the model year 2001 and is used for TV sets with screen sizes from 14” - 21”. The standard architecture consists of a Main panel, a Picture Tube panel, a Side (or Front) I/O panel and a Front Control panel. The Main panel consists primarily of conventional components with hardly any surface mounted devices.

The L01 is divided into 2 basic systems, i.e. mono and stereo sound. While the audio processing for the mono sound is done in the audio block of the UOC, an external audio processing IC is used for stereo sets.

The tuning system features 100 channels with on-screen display. The main tuning system uses a tuner, a microcomputer, and a memory IC mounted on the main panel. Also, in some type numbers, an FM radio is implemented with 40 pre-set channels. The microcomputer communicates with the memory IC, the customer keyboard, remote receiver, tuner, signal processor IC and the audio output IC via the I the settings for favourite stations, customer-preferred settings, and service/factory data. The on-screen graphics and closed caption decoding are done within the microprocessor, and then sent to the signal processor IC to be added to the main signal.

The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source. The chassis has a ‘hot’ ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis.

9.2.1 Stereo

Figure 9-1

The functions for video processing, microprocessor (µP) and teletext (TXT) decoder are combined in one IC (TDA958xH), the so-called Ultimate One Chip (UOC). This chip is (surface) mounted on the copper side of the main panel.

In stereo sets, the signal goes via the SAW filter (position 1004 in case of QSS demodulation and 1003 in case of Intercarrier demodulation), to the audio demodulator part of the UOC IC7200. The stereo audio output on pin 33 (or 38 for QSS) goes, via TS7206 or (TS7201 for QSS), to the stereo decoder

7831. The switch inside the stereo decoder 7831 selects (via I either the internal decoder or an external source. The NICAM + 2CS AM/FM stereo decoder is an ITT MSP34X5. The output is fed to the to the audio amplifier (AN7522 at position 7901). The volume level is controlled at this IC (pin 9) by a control line (VolumeMute) from the microprocessor. The audio signal is then sent to the speaker/headphone output panel.

9.2.3 FM radio (if present)

The FM radio uses the 10.7 MHz concept. This SIF frequency is available at pin 10 of the tuner. Via a pre-amplifier (TS7209 and TS7210), the signal is fed for demodulation to either the UOC (for mono FM radio) or by the Micronas MSP34X5 (for stereo FM radio).

9.3 Video Signal Processing

9.3.1 Introduction

The video signal-processing path consists of the following parts:

• RF signal processing.

• Video source selection.

• Video demodulation.

• Luminance/Chrominance signal processing.

• RGB control.

• RGB amplifier

The processing circuits listed above are all integrated in the UOC TV processor. The surrounding components are for the adaptation of the selected application. The I defining and controlling the signals.

9.3.2 RF Signal Processing

The incoming RF signal goes to the tuner (pos. 1000), where the IF signal is developed and amplified. The IF signals then exits the tuner from pin 11 to pass through the SAW filter (position 1002 in case of QSS demodulation and 1003 in case of Intercarrier demodulation). The shaped signal is then applied to the IF processor part of the UOC (pos. 7200). Tuner AGC (Automatic Gain Control) will reduce the tuner gain and thus the tuner output voltage when receiving strong RF signals. Adjust the AGC take-over point via the Service Alignment Mode (SAM). The tuner AGC starts working when the video-IF input reaches a certain input level and will adjust this level via the I tuner (pin 1) via the open collector output (pin 22) of the UOC. The IC also generates an Automatic Frequency Control (AFC) signal that goes to the tuning system via the I frequency correction when needed. The demodulated composite video signal is available at pin 38 and then buffered by transistor 7201.

9.3.3 Video Source Selection

The Composite Video Blanking Signal (CVBS) from buffer 7201 goes to the audio carrier trap filters (1200, 1201, or 1202 depending on the system used) to remove the audio signal. The signal then goes to pin 40 of IC7200. The internal input switch selects the following input signals:

• Pin 40: terrestrial CVBS input

• Pin 42: external AV1 CVBS input

• Pin 44: external Side I/O CVBS or AV2 Luminance (Y) input

• Pin 45: external AV2 Chrominance (C) input

Figure 9-5

Once the signal source is selected, a chroma filter calibration is performed. The received colour burst sub-carrier frequency is used for this. Correspondingly, the chroma band pass filter for PAL/NTSC processing or the cloche filter for SECAM processing is switched on. The selected luminance (Y) signal is supplied to the horizontal and vertical synchronisation processing circuit and to the luminance processing circuit. In the luminance-processing block, the luminance signal goes to the chroma trap filter. This trap is switched 'on' or 'off' depending on the colour burst detection of the chroma calibration circuit. The group delay correction part can be switched between the BG and a flat group delay characteristic. This has the advantage that in multi-standard receivers no compromise has to be made for the choice of the SAW filter.

9.3.4 Video Demodulation

The colour decoder circuit detects whether the signal is a PAL, NTSC or SECAM signal. The result is made known to the auto system manager. The PAL/NTSC decoder has an internal clock generator, which is stabilised to the required frequency by using the 12 MHz clock signal from the reference oscillator of the microcontroller/teletext decoder. The base-band delay line is used to obtain a good suppression of cross colour effects. The Y signal and the delay line outputs U and V are applied to the luminance/chroma signal processing part of the TV processor.

9.3.5 Luminance/Chrominance signal Processing

The output of the YUV separator is fed to the internal YUV switch, which switches between the output of the YUV separator or the external YUV (for DVD or PIP) on pins 51-53. Pin 50 is the input for the insertion control signal called ‘FBL-1’. When this signal level becomes higher than 0.9 V (but less than 3 V), the RGB signals at pins 51, 52 and 53 are inserted into the picture by using the internal switches. Also some picture improvement features are implemented in this part:

• Black stretch. This function corrects the black level of

incoming signals, which have a difference between the black level and the blanking level. The amount of extension depends upon the difference between actual black level and the darkest part of the incoming video signal level. It is detected by means of an internal capacitor.

• White stretch. This function adapts the transfer

characteristic of the luminance amplifier in a non-linear way depending on the average picture content of the luminance

signal. It operates in such a way that maximum stretching is obtained when signals with a low video level are received. For bright pictures, stretching is not active.

• Dynamic skin tone correction. This circuit corrects

(instantaneously and locally) the hue of those colours which are located in the area in the UV plane that matches the skin tone. The correction is dependent on the luminance, saturation and distance to the preferred axis.

The YUV signal is then fed to the colour matrix circuit, which converts it to R, G and B signals. The OSD/TXT signal from the microprocessor is mixed with the main signal at this point, before being output to the CRT board (pins 56, 57 and 58).

9.3.6 RGB Control

The RGB control circuit enables the picture parameters contrast, brightness and saturation to be adjusted, by using a combination of the user menus and the remote control. Additionally automatic gain control for the RGB signals via cutoff stabilisation is achieved in this functional block to obtain an accurate biasing of the picture tube. Therefor this block inserts the cut-off point measuring pulses into the RGB signals during the vertical retrace period.

The following additional controls are used:

• Black current calibration loop. Because of the 2-point

black current stabilisation circuit, both the black level and the amplitude of the RGB output signals depend on the drive characteristics of the picture tube. The system checks whether the returning measuring currents meet the requirements, and adapt the output level and gain of the circuit when necessary. After stabilisation of the loop, the RGB drive signals are switched on. The 2-point black level system adapts the drive voltage for each cathode in such a way that the two measuring currents have the right value. This is done with the measurement pulses during the frame flyback. During the first frame, three pulses with a current of 8 µA are generated to adjust the cut off voltage. During the second frame, three pulses with a current of 20 µA are generated to adjust the ‘white drive’. This has as a consequence, that a change in the gain of the output stage will be compensated by a gain change of the RGB control circuit. Pin 55 (BLKIN) of the UOC is used as the feedback input from the CRT base panel.

• Blue stretch. This function increases the colour

temperature of the bright scenes (amplitudes which exceed a value of 80% of the nominal amplitude). This effect is obtained by decreasing the small signal gain of the red and green channel signals, which exceed this 80% level.

• Beam current limiting. A beam current limiting circuit

inside the UOC handles the contrast and brightness control for the RGB signals. This prevents the CRT from being overdriven, which could otherwise cause serious damage in the line output stage. The reference used for this purpose is the DC voltage on pin 54 (BLCIN) of the TV processor. Contrast and brightness reduction of the RGB output signals is therefore proportional to the voltage present on this pin. Contrast reduction starts when the voltage on pin 54 is lower than 2.8 V. Brightness reduction starts when the voltage on pin 54 is less than 1.7 V. The voltage on pin 54 is normally 3.3 V (limiter not active). During set switch-off, the black current control circuit generates a fixed beam current of 1 mA. This current ensures that the picture tube capacitance is discharged. During the switch-off period, the vertical deflection is placed in an over-scan position, so that the discharge is not visible on the screen.

9.3.7 RGB Amplifier

From outputs 56, 57 and 58 of IC7200, the RGB signals are applied to the analogue output amplifiers on the CRT panel. The R-signal is amplified by a circuit built around transistors TS7311, 7312 and 7313, which drives the picture tube cathodes. For the other two signals see the blockdiagram in chapter 6. The supply voltage for the amplifier is +160 V and is derived from the line output stage.

9.4 Synchronisation

Inside IC7200 (part D), the vertical and horizontal sync-pulses are separated. These ‘H’ and ‘V’ signals are synchronised with the incoming CVBS signal. They are then fed to the H- and Vdrive circuits and to the OSD/TXT circuit for synchronisation of the On Screen Display and Teletext (or Closed Caption) information.

9.5 Deflection

9.5.1 Horizontal Drive

The horizontal drive signal is obtained from an internal VCO, which is running at twice the line frequency. This frequency is divided by two, to lock the first control loop to the incoming signal. When the IC is switched ‘on’, the ‘Hdrive’ signal is suppressed until the frequency is correct. The ‘Hdrive’ signal is available at pin 30. The ‘Hflybk’ signal is fed to pin 31 to phase lock the horizontal oscillator, so that TS7401 cannot switch ‘on’ during the flyback time. When the set is switched on, the ‘+8V’ voltage goes to pin 9 of IC7200. The horizontal drive starts up in a soft start mode. It starts with a very short T transistor. The T normal operation. The starting frequency during switch on is therefore about 2 times higher than the normal value. The ‘on’ time is slowly increased to the nominal value in 1175 ms. When the nominal value is reached, the PLL is closed in such a way that only very small phase corrections are necessary.

The ‘EHTinformation’ line on pin 11 is intended to be used as a ‘X-ray’ protection. When this protection is activated (when the voltage exceeds 6 V), the horizontal drive (pin 30) is switched 'off' immediately. If the ‘H-drive’ is stopped, pin 11 will become low again. Now the horizontal drive is again switched on via the slow start procedure. The ‘EHTinformation’ line (Aquadag) is also fed back to the UOC IC7200 pin 54, to adjust the picture level in order to compensate for changes in the beam current.

The filament voltage is monitored for ‘no’ or ‘excessive’ voltage. This voltage is rectified by diode 6413 and fed to the emitter of transistor TS7405. If this voltage goes above 6.8 V, TS7405 will conduct, making the ‘EHT0’ line ‘high’. This will immediately switch off the horizontal drive (pin 30) via the slow stop procedure.

The horizontal drive signal exits IC7200 at pin 30 and goes to TS7401, the horizontal driver transistor. The signal is amplified and coupled to the base circuit of TS7402, the horizontal output transistor. This will drive the line output transformer (LOT) and associated circuit. The LOT provides the extra high voltage (EHT), the VG2 voltage and the focus and filament voltages for the CRT, while the line output circuit drives the horizontal deflection coil.

Circuit Descriptions, Abbreviation List, and IC Data Sheets

9.5.2 Vertical Drive

A divider circuit performs the vertical synchronisation. The vertical ramp generator needs an external resistor (R3245, pin

20) and capacitor (C2244, pin 21). A differential output is

available at pins 16 and 17, which are DC-coupled with the vertical output stage. To avoid damage of the picture tube when the vertical deflection fails, the ‘V_GUARD’ output is fed to the beam current limiting input. When a failure is detected, the RGBoutputs are blanked. When no vertical deflection output stage is connected, this guard circuit will also blank the output signals.

These ‘V_DRIVE+’ and ‘V_DRIVE-‘ signals are applied to the input pins 7 and 1 of IC7471 (vertical deflection amplifier). These are voltage driven differential inputs. As the driver device (IC7200) delivers output currents, R3474 and R3479 convert them to voltage. The differential input voltage is compared with the voltage across measuring resistor R3471 that provides internal feedback information. The voltage across this measuring resistor is proportional to the output current, which is available at pin 5 where it drives the vertical deflection coil (connector 0222). IC7471 is supplied by +/-13 V. The vertical flyback voltage is generated at pin 3.

9.6.1 Introduction

The supply is a Switching Mode Power Supply (SMPS). The frequency of operation varies with the circuit load. This ‘QuasiResonant Flyback’ behaviour has some important benefits compared to a ‘hard switching’ fixed frequency Flyback converter. The efficiency can be improved up to 90%, which results in lower power consumption. Moreover the supply runs cooler and safety is enhanced. The power supply starts operating when a DC voltage goes from the rectifier bridge via T5520, R3532 to pin 8. The

V

OUT

operating voltage for the driver circuit is also taken from the ‘hot’ side of this transformer. The switching regulator IC 7520 starts switching the FET ‘on’ and ‘off’, to control the current flow through the primary winding of transformer 5520. The energy stored in the primary winding during the ‘on’ time is delivered to the secondary windings during the ‘off’ time. The ‘MainSupply’ line is the reference voltage for the power supply. It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 / 6540. This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 3 of 7520. The power supply in the set is ‘on’ any time AC power goes to the set.

Derived Voltages

The voltages supplied by the secondary windings of T5520 are:

• ‘MainAux’ for the audio circuit (voltage depends on set execution, see table below),

• 3.3 V and 3.9 V for the microprocessor and

• ‘MainSupply’ for the horizontal output (voltage depends on set execution, see table below).

Other supply voltages are provided by the LOT. It supplies +50 V (only for large screen sets), +13 V, +8 V, +5 V and a +200 V source for the video drive. The secondary voltages of the LOT are monitored by the ‘EHTinformation’ lines. These lines are fed to the video processor part of the UOC IC 7200 on pins 11 and 34. This circuit will shut ‘off’ the horizontal drive in case of overvoltage or excessive beam current.

Degaussing

When the set is switched on, the degaussing relay 1515 is immediately activated as transistor 7580 is conducting. Due to the RC-time of R3580 and C2580, it will last about 3 to 4 seconds before transistor 7580 is switched off.

9.6.2 Basic IC Functionality

For a clear understanding of the Quasi-Resonant behaviour, it is possible to explain it by a simplified circuit diagram (see Figure below). In this circuit diagram, the secondary side is transferred to the primary side and the transformer is replaced by an inductance L the resonance capacitor C

. CD is the total drain capacitance including

the MOSFET and the winding capacitance C transformer. The turns ratio of the transformer is represented by n (N

In the Quasi-Resonant mode each period can be divided into four different time intervals, in chronological order:

• Interval 1: t0 < t < t1 primary stroke At the beginning of the first interval, the MOSFET is switched ‘on’ and energy is stored in the primary inductance (magnetisation). At the end, the MOSFET is switched ‘off’ and the second interval starts.

• Interval 2: t1 < t < t2 commutation time In the second interval, the drain voltage will rise from almost zero to V

The moment that the voltage on pin 1 drops below the ‘under voltage lock out‘ level (UVLO = ± 9 V), the IC will stop switching and will enter a safe restart from the rectified mains voltage.

Operation

The supply can run in three different modes depending on the output power:

• Quasi-Resonant mode (QR) The QR mode, described above, is used during normal operation. This will give a high efficiency.

• Frequency Reduction mode (FR) The FR mode (also called VCO mode) is implemented to decrease the switching losses at low output loads. In this way the efficiency at low output powers is increased, which enables power consumption smaller than 3 W during stand-by. The voltage at the pin 3 (Ctrl) determines where the frequency reduction starts. An external Ctrl voltage of 1.425 V corresponds with an internal VCO level of 75 mV. This fixed VCO level is called V reduced in relation to the VCO voltage between 75 mV and 50 mV (at levels larger than 75 mV, Ctrl voltage < 1.425V, the oscillator will run on maximum frequency f kHz typically). At 50 mV (V reduced to the minimum level of 6 kHz. Valley switching is still active in this mode.

• Minimum Frequency mode (MinF) At VCO levels below 50 mV, the minimum frequency will remain on 6 kHz, which is called the MinF mode. Because of this low frequency, it is possible to run at very low loads without having any output regulation problems.

Safe-Restart Mode

This mode is introduced to prevent the components from being destroyed during eventual system fault conditions. It is also used for the Burst mode. The Safe-Restart mode will be entered if it is triggered by one of the following functions:

• Over voltage protection,

• Short winding protection,

• Maximum ‘on time’ protection,

•V

• Detecting a pulse for Burst mode,

• Over temperature protection.

When entering the Safe-Restart mode, the output driver is immediately disabled and latched. The V charge the V

In Standby, the power supply works in ‘burst mode’. Burst mode can be used to reduce the power consumption below 1 W at stand-by. During this mode, the controller is active (generating gate pulses) for only a short time and for a longer time inactive waiting for the next burst cycle. In the active period the energy is transferred to the secondary and stored in the buffer capacitor C

in front of the linear

STAB

stabiliser (see Figure below). During the inactive period, the load (e.g. microprocessor) discharges this capacitor. In this mode, the controller makes use of the Safe-Restart mode.

Burst-Mode stand-b y on/off from microprocessor

Figure 9-14

The system enters burst mode standby when the microprocessor activates the ‘Stdby_con’ line. When this line is pulled high, the base of Q7541 is allowed to go high. This is triggered by the current from collector Q7542. When Q7541 turns ‘on’, the opto-coupler (7515) is activated, sending a large current signal to pin 3 (Ctrl). In response to this signal, the IC stops switching and enters a ‘hiccup’ mode. This burst activation signal should be present for longer than the ‘burst blank’ period (typically 30 µs): the blanking time prevents false burst triggering due to spikes. Burst mode standby operation continues until the microcontroller pulls the ‘Stdby_con’ signal low again. The base of Q7541 is unable to go high, thus cannot turn ‘on’. This will disable the burst mode. The system then enters the startup sequence and begins normal switching behaviour.

For a more detailed description of one burst cycle, three time intervals are defined:

• t1: Discharge of V

when gate drive is active During the

first interval, energy is transferred, which result in a rampup of the output voltage (V

) in front of the stabiliser.

STAB

When enough energy is stored in the capacitor, the IC will be switched ‘off’ by a current pulse generated at the secondary side. This pulse is transferred to the primary side via the opto coupler. The controller will disable the output driver (safe restart mode) when the current pulse reaches a threshold level of 16 mA into the Ctrl pin. A resistor R

9.6.3 Protection Events

The SMPS IC 7520 has the following protection features:

Demagnetisation sense

This feature guarantees discontinuous conduction mode operation in every situation. The oscillator will not start a new primary stroke until the secondary stroke has ended. This is to ensure that FET 7521 will not turn on until the demagnetisation of transformer 5520 is completed. The function is an additional protection feature against:

• saturation of the transformer,

• damage of the components during initial start-up,

• an overload of the output. The demag(netisation) sense is realised by an internal circuit that guards the voltage (Vdemag) at pin 4 that is connected to V

winding by resistor R1 (R3522). The Figure below shows

CC

the circuit and the idealised waveforms across this winding.

e

Figure 9-16

Over Voltage Protection

The Over Voltage Protection ensures that the output voltage will remain below an adjustable level. This works by sensing the auxiliary voltage via the current flowing into pin 4 (DEM) during the secondary stroke. This voltage is a well-defined replica of the output voltage. Any voltage spikes are averaged by an internal filter. If the output voltage exceeds the OVP trip level, the OVP circuit switches the power MOSFET ‘off’. Next, the controller waits until the ‘under voltage lock out‘ level (UVLO = ± 9 V) is reached on pin 1 (V

). This is followed by a

CC

safe restart cycle, after which switching starts again. This process is repeated as long as the OVP condition exists. The output voltage at which the OVP function trips, is set by the demagnetisation resistor R3522.

Over Current Protection

The internal OCP protection circuit limits the ‘sense’ voltage on pin 5 to an internal level.

Over Power Protection

During the primary stroke, the rectified AC input voltage is measured by sensing the current drawn from pin 4 (DEM). This current is dependent on the voltage on pin 9 of transformer 5520 and the value of R3522. The current information is used to adjust the peak drain current, which is measured via pin I

.

SENSE

Short Winding Protection

If the ‘sense’ voltage on pin 5 exceeds the short winding protection voltage (0.75 V), the converter will stop switching. Once V

drops below the UVLO level, capacitor C2521 will be

CC

recharged and the supply will start again. This cycle will be repeated until the short circuit is removed (safe restart mode). The short winding protection will also protect in case of a secondary diode short circuit. This protection circuit is activated after the leading edge blanking time (LEB).

LEB time

The LEB (Leading Edge Blanking) time is an internally fixed delay, preventing false triggering of the comparator due to current spikes. This delay determines the minimum ‘on’ time of the controller.

Over Temperature protection

When the junction temperature exceeds the thermal shutdown temperature (typ. 140º C), the IC will disable the driver. When the V

voltage drops to UVLO, the VCC capacitor will be

CC

recharged to the V the V

voltage will drop again to the UVLO level (Safe-Restart

mode). This mode will persist until the junction temperature drops 8 degrees typically below the shutdown temperature.

Mains dependent operation enabling level

To prevent the supply from starting at a low input voltage, which could cause audible noise, a mains detection is implemented (Mlevel). This detection is provided via pin 8, that detects the minimum start-up voltage between 60 and 100 V. As previous mentioned, the controller is enabled between 60 and 100 V. An additional advantage of this function is the protection against a disconnected buffer capacitor (C supply will not be able to start-up because the V

capacitor

will not be charged to the start-up voltage.

9.7.1 Introduction

The microprocessor part of the UOC, has the complete control and teletext on board. User menu, Service Default Mode, Service Alignment Mode and Customer Service Mode are generated by the µP. Communication to other ICs is done via

2

the I

C-bus.

2

9.7.2 I

C-Bus

The main control system, which consists of the microprocessor part of the UOC (7200), is linked to the external devices (tuner, NVM, MSP, etc) by means of the I

2

C-bus. An internal I2C-bus is used to control other signal processing functions, like video processing, sound IF, vision IF, synchronisation, etc.

9.7.3 User Interface

There are two control signals, called ‘KEYBOARD_protn’ and ‘IR’. Users can interact either through the Remote Control transmitter, or by activation of the appropriate keyboard buttons. The L01 uses a remote control with RC5 protocol. The incoming signal is connected to pin 67 of the UOC. The 'Top Control' keyboard, connected to UOC pin 80, can also control the set. Button recognition is done via a voltage divider.

The front LED (6691) is connected to an output control line of the microprocessor (pin 5). It is activated to provide the user information about whether or not the set is working correctly (e.g., responding to the remote control or fault condition)

9.7.4 Sound Interface

There are three control signals, called ‘Volume_Mute’, ‘Treble_Buzzer_Hosp_app’ and ‘Bass_panorama’.

The ‘Volume_Mute’ line controls the sound level output of the audio amplifier or to mute it in case of no video identification or from user command. This line also controls the volume level during set switch ‘on’ and ‘off’ (to prevent audio plop).

The ‘Treble’ and ‘Bass’ lines are used (in mono 4:3 sets) to switch between different smart sound modes.

three lines:

• STATUS1 This signal provides information to the

microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe). This signal is not connected in NAFTA sets.

• STATUS2 This signal provides information to the

microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe). For sets with an SVHS input it provides the additional information if a Y/C or CVBS source is present. The presence of an external Y/C source makes this line ‘high’ while a CVBS source makes the line ‘low’.

• SEL-MAIN-FRNT-RR This is the source select control

signal from the microprocessor. This control line is under user control or can be activated by the other two control lines.

9.7.6 Power Supply Control

The microprocessor part is supplied with 3.3 V and 3.9 V both derived from the ‘MainAux’ voltage via a 3V3 stabiliser (7560) and a diode.

Figure 9-17

Two signals are used to control the power supply:

• Stdby_con This signal is generated by the microprocessor

when over-current takes place at the ‘MainAux’ line. This is

EN 56 L01.2A AB9.

Circuit Descriptions, Abbreviation List, and IC Data Sheets

done to enable the power supply into standby burst mode, and to enable this mode during a protection. This signal is ‘low’ under normal operation conditions and goes to ‘high’ (3.3 V) under ‘standby’ and ‘fault’ conditions.

• POWER_DOWN This signal is generated by the power

supply. Under normal operating conditions this signal is ‘high’ (3.3 V). During ‘standby’ mode, this signal is a pulse train of approx. 10 Hz and a ‘high’ duration of 5 ms. It is used to give information to the UOC about the fault condition in the Audio amplifier supply circuit. This information is generated by sensing the current on the ‘MainAux’ line (using voltage drop across R3564 to trigger TS7562). This signal goes ‘low’ when the DC-current on the ‘MainAux’ line exceeds 1.6 - 2.0 A. It is also used to give an early warning to the UOC about a power failure. Then the information is used to mute the sound amplifier to prevent a switch off noise and to solve the switch-off spot.

9.7.7 Tuner IF

Pin 3 of the UOC (SEL-IF-LL’_M-TRAP), is an output pin to switch the SAW-filter to the appropriate system.

• If UOC pin 3 is ‘low’, the selected system is: – West Europe: PAL B/G, I, SECAM L/L’ – East Europe: PAL B/G – Asia Pacific: NTSC M

• If UOC pin 3 is ‘high’, the selected system is: – West Europe: SECAM L’, L’-NICAM – East Europe: PAL D/K – Asia Pacific: PAL B/G, D/K, I

9.7.8 Protection Events

Several protection events are controlled by the UOC:

• BC protection, to protect the picture tube from a too high beam current. The UOC has the capability of measuring the normal back level current during the vertical flyback. So if for some reason the CRT circuit is malfunctioning (i.e. high beam current), the normal black current will be out of the 75 µA range, and the UOC will trigger the power supply to shut down. However, this is a high beam-current situation, the TV screen will be bright white before the set is shut down.

• E/W protection, two protection mechanisms are built in, over-current and over-voltage. – In case of over-current due to defective parts in the line

deflection output stage, a high current will flow through resistors 3405//3406. If this current is large enough to create a voltage drop of 0.7 V across 3405//3406, transistor TS7606 (in A7 diagram) will conduct and pin 80 of the UOC will be pulled down. Thereafter, the UOC will shut down the power supply. In case of further current increase, the fused resistor 3411 is built-in for double protection.

– In case of a high voltage appearing across capacitor

2401 (dependent of the tube size), which is high enough to trigger zener diode 6401 into conduction, transistor TS7606 (in A7 diagram) will conduct and UOC is triggered to shut down the power supply.

2

• I

C protection, to check whether all I2C IC's are

functioning.

In case one of these protections is activated, the set will go into ‘standby’.

The ‘on’ and ‘standby’ LEDs are controlled via the UOC.
