Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

Index of this chapter:

2.1 Safety Instructions

2.2 Maintenance Instructions

2.3 Warnings

2.4 Notes
Note: Figures below can deviate slightly from the actual situation, due to the different set executions.
2.1 Safety Instructions
Safety regulations require that during a repair:
Due to the chassis concept, a very large part of the circuitry (incl. deflection) is “hot”. Therefore, connect the set to the mains via an isolation transformer (> 800 VA).
Replace safety components, indicated by the symbol h, only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard.
Wear safety goggles when you replace the CRT.
Safety regulations require that after a repair, you must return the set in its original condition. Pay, in 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 this is valid for the:
1. Pins of the line output transformer (LOT).
2. Fly-back capacitor(s).
3. S-correction capacitor(s).
4. Line output transistor.
5. Pins of the connector with wires to the deflection coil.
6. 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 mains cord for external
damage.
Check the strain relief of the mains cord for proper function,
to prevent the cord from touching the CRT, hot components, or heat sinks.
Check the electrical DC resistance between the mains plug
and the secondary side (only for sets that have an isolated power supply). Do this as follows:
1. Unplug the mains cord and connect a wire between the two pins of the mains plug.
2. Turn on the main power switch (keep the mains cord unplugged!).
3. Measure the resistance value between the pins of the mains plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 Mohm and 12 Mohm.
4. Switch the TV “off” and remove the wire between the two pins of the mains plug.
Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.
When a customer uses the set 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 V_dc). Discharge until the meter reading is 0 V (after approx. 30 s).
V

Figure 2-1 Discharge picture tube

All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD, w). Careless handling during repair can reduce life drastically. Make sure that, during repair, 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 earth 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. We do not recommend adjusting this unit during repair.
Be careful during measurements in the high voltage section and on the picture tube.
Never replace modules or other components while the unit is “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.
E_06532_007.eps
250304
2.2 Maintenance Instructions
We recommend a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions:
When a customer uses the set under normal circumstances, for example in a living room, the recommended interval is three to five years.

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 “Service Modes, ....”) 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 standby (F). These values are indicated by means of the appropriate symbols.
The picture tube panel 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 interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

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.
More Information
For more information on how to handle BGA devices, visit this URL: www.atyourservice.ce.philips.com (needs subscription, not available for all regions). After login, select “Magazine”, then go to “Workshop Information”. Here you will find Information on how to deal with BGA-ICs.

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 expressed in micro-farads (µ= x 10^-6), nano-farads (n= x 10^-9), or pico-farads (p= x 10^-
12).
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 Electrical Replacement 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.

2.4.4 Lead Free Solder

Philips CE is going to produce lead-free sets (PBF) from
1.1.2005 onwards.
P
b
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 next 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.
EN 6 EM5.3A P/M AA3.
Directions for Use
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 wether 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).

3. Directions for Use

You can download this information from the following website:
http://www.philips.com/support
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) You will find this and more technical information within the "Magazine", chapter "Workshop information". For additional questions please contact your local repair­helpdesk.

2.4.5 Practical Service Precautions

It makes sense to avoid exposure to electrical shock. While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.
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.

5.1 Test Points
The EM5 chassis is equipped with test points printed on the circuit board assemblies. They refer to the schematic diagram letters. The numbering is in a logical sequence for diagnostics. Always start diagnosing (within a functional block), in the sequence of the relevant test points for that block.
Perform measurements under the following conditions:
Set in Service Default Mode.
Video: color bar signal.
Audio: 3 kHz left, 1 kHz right.
5.2 Service Modes
Service Default Mode (SDM) and Service Alignment Mode (SAM) offer several features for the service technician, while the Customer Service Mode (CSM) is used for communication between a Philips Customer Care Centre (P3C) and a customer.
There is also the option of using ComPair, a hardware interface between a computer (see requirements below) and the TV chassis. It offers the ability of structured troubleshooting, test pattern generation, error code reading, software version readout, and software upgrading. Minimum requirements: a Pentium processor, Windows 95/ 98, and a CD-ROM drive (see also paragraph "ComPair").
Note: This chassis is equipped with a LED configuration with separate blue and red LEDs. This is different from the bicoloured version we know from EM5E. The blue LED is controlled by software (via ON_OFF_LED). The red LED will light in anti-phase to the blue one, but with a time delay. This means that if the blue LED is blinking fast, the red LED will stay off. But after the blue LED is "OFF" long enough, the red LED will go "ON". So take care: In certain service modes (e.g. blinking LED, stepwise start-up, etc.) you must observe the blue LED and ignore the red LED.

5.2.1 Service Default Mode (SDM)

Purpose
To create a pre-defined setting, to get the same measurement results as given in this manual.
To override SW protections.
To start the blinking LED procedure.
Specifications

menu will appear. To switch it off, push the "MENU" button again.
When you shorten for a moment the two solder pads on the 'external part' of the SSB print, with the indication "SDM". Activation can be performed in all modes, except when the set has a problem with the main-processor. Caution: If the SDM is entered via the pins, all the software-controlled protections are de-activated.
Use the "DEFAULT" button in the DST-emulation feature of ComPair.
Use the "DEFAULT" button on the Dealer Service Tool (RC7150).
After entering this mode, "SDM" will appear in the upper right corner of the screen.
How to navigate
When you press the "MENU" button on the RC transmitter, the set will toggle between the SDM and the normal user menu (with the SDM mode still active in the background).
How to exit SDM
Use one of the following methods:
Switch the set to STANDBY via the RC-transmitter.
Press the "EXIT" button in the DST-emulation feature of ComPair.
Via a standard customer RC-transmitter: key in "00"­sequence.

5.2.2 Service Alignment Mode (SAM)

Purpose

Short for a moment the two solder pads on the 'external part' of the SSB print, with the indication SAM. Depending on the software version it is possible that the service warning will appear, you can continue by pressing any digit key on the RC.
EN 12 EM5.3A P/M AA5.
Service Modes, Error Codes, and Fault Finding
Use the DST-emulation feature of ComPair.
Press the ALIGN button on the DST while the set is in the normal operation
After entering this mode, "SAM" will appear in the upper right corner of the screen.
Contents of SAM:
OPERATION HOURS. Displays the accumulated total of operation hours (not the standby hours).
HARDWARE INFO ROM VERSION. Displays the date of the software and
the software version of the ROM (example: EM53AP_
1.0_01234 = AAAABB-X.Y_NNNNN).
AAAA= the chassis name.
BB= the region: EU= Europe, AP= Asia Pacific PAL/Multi, AN= Asia Pacific NTSC, US= USA, LT= LATAM.
X.Y= the software version, where X is the main version number (different numbers are not compatible with one another) and Y is the sub version number (a higher number is always compatible with a lower number).
NNNNN= last five digits of 12nc code software.
FBX VERSION. The 12NC-number of the build in
Feature Box software.
ERRORS (followed by maximal 10 errors). The most recent error is displayed at the upper left (for an error explanation see paragraph "Error Codes").
DEFECTIVE MODULE. Here the module that generates the error is displayed. If there are multiple errors in the buffer, which are not all generated by a single module, there is probably another defect. It will then display the message "UNKNOWN" here.
RESET ERROR BUFFER. When you press the "OK" button, the error buffer is reset.
ALIGNMENTS. This will activate the "ALIGNMENTS" sub­menu.
DEALER OPTIONS. Extra features for the dealers.
SERVICE OPTIONS. Extra features for Service.
INITIALISE NVM. When an NVM was corrupted (or replaced) in the former EM3 chassis, the microprocessor replaces the content with default data (to assure that the set can operate). However, all pre-sets and alignment values are gone now, and option numbers are not correct. Therefore, this was a very drastic way. In this chassis, the procedure is implemented in another way: The moment the processor recognises a corrupted NVM, the "INITIALISE NVM" line will be highlighted. Now, you can do two things (dependent of the service instructions at that moment): – Save the content of the NVM via ComPair for
development analysis, before initialising. This will give the Philips Service department an extra possibility for diagnosis (e.g. when Development asks for this).
– Initialise the NVM (same as in the past, however now it
happens conscious).
STORE. All options and alignments are stored when pressing the "OK"-button
FUNCTIONAL TEST. All devices are tested via the "OK" button. Eventual errors are displayed in the error buffer. The error buffer is not erased, the content returns when this test is terminated.
DAILY MENUS. With the "OK" button, you can go to the normal user menu. SAM is still active in the background. With the "MENU" button, you return from the user menu to SAM menu. This feature can be helpful to quickly change some settings in the user menu.
SW MAINTENANCEUPGRADE. Not applicable for this chassis – EVENTS. Not useful for service purposes. In case of
specific software problems, the development department can ask for this info.
BDM INFO. Broadcast Debug Menu info. The purpose
of this menu is to debug the broadcast, NOT the TV.
The menu gives an overview of what is received on the current preset. Following items are displayed:

5.2.3 Customer Service Mode (CSM)

Purpose
When a customer is having problems with his TV-set, he can call his dealer. The service technician can than ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severity of the complaint. In many cases, he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer. The CSM is a read only mode; therefore, modifications in this mode are not possible.
How to enter CSM
Use one of the following methods:
Press the "MUTE" button on the RC-transmitter simultaneously with the "MENU" button on the TV (top control) for at least 4 seconds.
Key in the code "123654" via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user) menu on the screen!
How to navigate
By means of the "CURSOR-DOWN/UP" knob on the RC­transmitter, you can navigate through the five menus.

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. For this chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector.
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 can access the I and receive I
2
C bus of the television. ComPair can send
2
C commands to the micro controller of the
television. In this way, it is possible for ComPair to communicate (read and write) to devices on the I 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 extends. When this is not the case, ComPair will guide you through the faultfinding tree by asking you questions (e.g. Does the screen give 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 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 Mono-carrier. – 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.

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.

5.4.3 Stepwise Start-up

Under normal circumstances, a fault in the power supply, or an error during start-up, will switch the television to protection mode. ComPair can take over the initialisation of the television. In this way, it is possible to distinguish which part of the start­up routine (hence which circuitry) is causing the problem. Take notice that the transition between two steps can take some time, so give the set some time to reach a stable state. During the transition time the LED can blink strangely.
Stepwise start- up explanation
This is realised via ComPair and is very helpful when a protection is activated (see also chapter "Protections").

Note (*):
When the set is in stepwise mode and, due to stepping-up, a protection is activated, the set will really go into protection (blinking LED). The set will not leave the stepwise-mode however. If state X is the state where the set went to protection, stepwise start-up will return to state X-1. At state (X-1) diagnostic measurements can be performed. Also, in the short time the set is in state X but not yet in protection, you can also do some measurements.

5.5 Error Codes

5.5.1 Introduction

The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right, new errors are logged at the left side, and all other errors shift one position to the right. When an error has occurred, the error is added to the list of errors, provided the list is not full or the error is a protection error. When an error occurs and the error buffer is full, then the new error is not added, and the error buffer stays intact (history is maintained), except when the error is a protection error. To prevent that an occasional error stays in the list forever, the error is removed from the list after 50+ operation hours. When multiple errors occur (errors occurred within a short time span), there is a high probability that there is some relation between them.

5.5.2 How to read the Error Buffer

Use one of the following methods:
On screen via the SAM (only if you have a picture). Examples: – 0 0 0 0 0: No errors detected – 6 0 0 0 0: Error code 6 is the last and only detected
error
9 6 0 0 0: Error code 6 was first detected and error
code 9 is the last detected error
Via the blinking LED procedure (when you have no picture). See next paragraph.
•Via ComPair.

5.5.3 How to clear the Error Buffer

Use one of the following methods:
By activation of the "RESET ERROR BUFFER" command in the SAM menu.
With a normal RC, key in sequence "MUTE" followed by "062599" and "OK".
When you transmit the commands "DIAGNOSE" - "99" ­"OK" with ComPair (or with a DST).
If the content of the error buffer has not changed for 50+ hours, it resets automatically.

5.5.4 Error Codes

In case of non-intermittent faults, clear the error buffer before you begin the repair. This to ensure that old error codes are no longer present. Before clearing the buffer, write down the content, as this history can give you significant information.
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).
There are various errors:
2
•I
C device errors.
2
•I
C bus errors.
Protection errors.
Errors not related to an I – BLACK CURRENT LOOP (ERROR 28): detection of a
continuous fail of the black current stabilisation loop of the HOP.
FEM (ERROR 26): at start-up, after initialisation of the
PICNIC, the presence of the FALCONIC can be checked.
EAGLE (ERROR 27): at start-up, after initialisation of
the PICNIC, the presence of the Eagle can be checked.

Note:
Error codes 1, 6, or 18 are protection codes and in this case, supplies of some circuits will be switched "OFF". Also, in protection, the LED will blink the number of times equivalent to the most recent error code.

5.6 The Blinking LED Procedure

5.6.1 Introduction

Via this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful for fault finding, when there is no picture.
When the SDM is entered, the front LED will show (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 (where "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: Error 12 9 6 0 0. After activation of the SDM, the red front LED will show:
1 long blink of 750 ms (which is an indication of the decimal digit) 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.
Note: If errors 1, 6 or 18 occur, the LED always gives the last occurred error even if the set is NOT in service mode.

5.6.2 How to Enter

Use one of the following methods:
Enter the SDM (only via soldering pads marked "SDM" on SSB). The blinking red front LED will show the entire contents of the error buffer (this works in "normal operation" mode and in "protection" mode).
Transmit the commands "MUTE" - "062500" - "OK" with a normal RC. The complete error buffer is shown. Take notice that it takes some seconds before the blinking led LED starts.
Transmit the commands "MUTE" - "06250x" - "OK" with a normal RC (where "x" is a number between 1 and 5). When x= 1 the last detected error is shown, x= 2 the second last
error, etc.... Take notice that it takes some seconds before
the blinking led LED starts.
"DIAGNOSE X" with the DST (where "x" is a number between 1 and 5). When x= 1 the last detected error is
shown, x= 2 the second last error, etc.... When x = 0 all
errors are shown.

5.7 Protections

5.7.1 Introduction

This chassis has only one microprocessor (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. Therefore, 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 is put in protection mode. The protection mode is indicated by the blinking of the front LED at a frequency of 3 Hz (or by a coded blinking in special cases). In some error cases however, the microprocessor does not put the set in the protection mode (this is the case with the ­hardware - loudspeaker protection of the audio amplifier).
The content of the error buffer can be read via the service menu (SAM), the blinking LED procedure or via DST/ComPair.
To get a quick diagnosis, this 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). In this mode, items of the set can be adjusted via a menu.
You can enter both SDM and SAM modes via the 'service pads' on the SSB, via an RC-transmitter (DST or standard RC), or via ComPair. It is not possible to enter the SAM in "standby"; the TV has to be in "normal operation" mode.
The "Protection Diagram" shows the structure of the protection system. See diagram below.

There are several types of protections:

•I
C related protections.
OTC related protections (via polling on I/O pins or via algorithms).
HOP related protections (mainly for deflection items).
Hardware errors that are not sensed by the OTC (e.g. vertical flyback protection, bridge coil protection, E/W protection, arcing protection).
All protections are explained below.

C controlled ICs are

5.7.3 OTC Related Protections

If a protection is detected at an OTC input, the OTC will start to scan all protection inputs every 200 ms for 5 times. If the protection on one of the inputs is still active after 1 s, the microprocessor will put the set in the protection mode. Before the scanning is started, a so-called "ESD refresh" is carried out. This is done, because the interrupt on one of the inputs is possibly caused either by a flash or by ESD. As a flash or ESD can influence IC settings, the HIP, MSP, 3D Comb (US only) and wireless module are initialised again, to ensure the normal picture and sound conditions of the set.
8 V and 5 V protection: The microprocessor senses the presence of the 8 V and 5 V (via the "+5V_CON" and "+8V_CON" lines). If one (or both) of these voltages is (are) not present, an error code is stored in the error buffer of the NVM, and the set is put in the protection mode.

of the inputs of the HOP, the relevant error bit in the HOP register is set to "high". If this error bit is still "high" after 1 s, the OTC will store the error code in the error buffer of the NVM and, depending on the relevancy of the error bit, the set will either go into the protection mode or not.
The following protections are implemented:
HFB (Horizontal Flyback): If the horizontal flyback is not present, 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.
XPR (X-ray protection): If the HFB pulses are too low (level detection), the HOP will detect this via the XPR-bit. The error will be logged in the error buffer and the set will go into protection mode.
Note: Both errors will be logged as HFB-failure.

5.7.5 Hardware Related Protections

Due to the architecture ("hot" deflection), some protections cannot be sensed by the microprocessor. Three of these protections will lead to a protection on set level (Standby mode and blinking LED), while another will only lead to a circuit protection.
TV-set Protection
The following fault conditions will lead to a "complete" set protection:
BRIDGECOIL protection: This is sensed via the "EW" signal going to the base of TS7652 (via R3495 and D6499). In a normal situation, the voltage on C2498 (diagram A4) is high and TS7652 is conducting. When bridge coil 5422 (diagram A3) is short circuited, the voltage on C2498 changes to low, which will block TS7652. In this case, also TS7641 will block and the voltage on 2642 will rise until TS7443 is forced in conduction. The "SUP-ENABLE" signal (in normal operating condition -20 V) is shorted now to ground level, which will force the Main Power Supply to Standby mode.
ARC protection: If there are "open" connections (e.g. bad solder joints) in the high-energy deflection circuitry, this can lead to damaging effects (read: fire). For that reason, the E/ W current is sensed (via 3479//3480). If this current becomes too high, the "thyristor" circuit (TS7653 and TS7654) is triggered. TS7442 is switched "on" and TS7443 is forced into conduction. . The "SUP-ENABLE" signal is shorted now to ground level, which will force the Main Power Supply to Standby mode.
NON_VFB (No vertical Flyback) protection: If the frame stage generates no pulses, TS7641 will block. TS7443 is now switched "on", which will lead to Standby mode. Therefore, in normal operation condition, TS7641 and TS7652 are conducting, while TS7443 is blocked.
Circuit Protection
The following fault condition will lead to a "partly" set protection:
PROT1 (DC) protection: When a DC-voltage (positive or negative) is sensed on one of the loudspeaker outputs, the protection circuit (TS7704, 7705, 7706 and 7707 in diagram A6) will put the IC7700 in Standby mode (via tri­state input pin 6). For more details, see chapter "Circuit Descriptions".

5.7.4 HOP Related Protections

5.8 Repair tips

5.8.1 Miscellaneous

The relay you hear when you switch the set "on" (from Standby or via the mains switch), is from the degaussing circuitry. It is not used for switching the Power Supply (as done in the MG­chassis).
Take care not to touch the "hot" heatsink while disconnecting the SSB, despite the fact that the mains cord is out of the mains socket. There can still be an annoying rest-voltage on the heatsink for a short while. This, because the discharge resistors 3502 and 3503 (on the LSP between hot and cold part) are not stuffed for Europe. Instead, discharge resistors 3066 and 3057 on the Mains Switch panel are used, but because they are located before the Mains switch, they only discharge when this switch is "on". Advice: when you remove the SSB, disconnect the Mains cord, but keep the Mains Switch "on".
Do not try to measure on the SSB side, which is facing the 'hot' heatsink. This is dangerous. Most service test points are guided to the 'tuner' side and are indicated by the 'service' printing. Where the circuitry was too "crowded" for service printing, you can find the correct location on the "test point overviews" in this manual. A very large part of the LSP is "hot", such as:
The primary part of the Standby Supply.
The whole Main supply (except for the secondary Audio supply).
And the complete deflection circuitry (so notice that the deflection coil is hot!).

6. When you switch "off" the set, this is done in a controlled way via the POR signal [3].
Note: Standby is not directly achieved via the Standby line of the microprocessor, but indirectly via the HOP circuitry.

5.8.3 ComPair

This chassis does not have an IR transmitting LED (as in MG­sets). Therefore, a "Service" (ComPair) connector is implemented at the rear side of the set, which is directly accessible (as in A10-, EM2E-, EM3E and EM5E-sets). In addition to this, there is also a blinking LED procedure to show the contents of the error buffer.
When you use ComPair, you have the possibility to activate a "stepwise start-up" mode. With this mode, you can initiate the start-up sequence step by step. This also means that in certain steps, some protections are not activated. This is sometimes very convenient during repair.

5.8.4 Protections

Activating SDM via the "service pads" will overrule the processor-controlled protections, but not the hardware protections. This means, that the A/D-input protections (5 and 8 V) and the I
2
C "not-acknowledging" info of the feature box
(FBX) and of the Tuner are overruled. Caution: When doing this, the service technician must know what he is doing, as it could lead to damaging the set.
The "ARC"- and/or "BRIDGECOIL" protection are hardly ever triggered, however:
When you suspect the "ARC" protection, look for bad solder joints and smell. By interrupting resistor 3497, this protection is disabled (special attention needed!).
When you suspect the "BRIDGECOIL" protection, which can also be due to a too wide picture amplitude, shorten G and S of the E/W MOSFET 7480. This will disable the protection. You will now have minimal horizontal amplitude. Re-align the horizontal amplitude in the SAM menu and remove the G/S short of TS7480.

5.8.5 Main Supply

The simplest way is, to replace the components of the Main Supply with repair kit 3122 785 90310.
More detailed way:
1. Replace FET 7504 and zener 6505.
2. Remove the SSB panel.
3. Short B and E of TS7529, in order to put the Main Supply in "on"-mode (TS7529 is blocking then). Caution: To prevent that R3403 and TS7443 will be damaged, first disable the HW-protection of the deflection circuit. Therefore short circuit C2642 on the LSP (diagram A4).
4. Attach a load of 500 O to V_BAT capacitor C2515 (the supply can not work without a minimum load).
5. Use a variac, and slowly increase the V_MAINS. Measure over sensing resistors R3514//15, if a nice sawtooth voltage becomes available.
6. Also measure the V_BAT. This may never exceed +141 V. If it does, there is something wrong in the feedback circuitry (e.g. regulator 7506).
Note: Be careful when measuring on the gate of FET TS7504. This circuitry is very high ohmic and can easily be damaged (first connect ground to measuring equipment, than measure the gate).

The simplest way is to replace the components of the Line Deflection circuitry with repair kit 3122 785 90330.

5.8.8 Frame Deflection

Caution: When the Frame Deflection circuitry is suspected,
one must be careful. Because there is a DC-voltage on the frame deflection, the beam current could damage the CRT
neck, leading to a defective CRT.

3. Measure with a multi-meter, or better with a oscilloscope, the functionality of the Frame stage.
4. After you have found the cause, exchange the defective component (e.g. TDA8177), and re-solder the interrupted resistors.
When the Mains switch is 'on', this voltage must always be available
In case of a bad connection, it can happen that there is no picture, and that the Standby LED is not controllable. Re-place the SSB.
You have no picture, so:
- Read the error buffer via ComPair (error buffer is accessible when set is in protection, compare­file will guide you to this)
- Read the blinking LED information via standard remote command <mute>06250X<ok>
- Or you read the error code sequence via standard remote command <mute>062500<ok>.
When you have found the error, check the circuitry related to the supply voltage and I2C­communication or the circuitry that triggers the protection.
As processor cannot communicate with one of the 2 busses it the standb y-led spontaneously starts blinking 6-6-6... or 18-18-18... If in the error buffer somewhere is an error 6 or 18, these will have the highest priority starting the mentioned blinking. Measure dependent of the error on the I2C-bus which device is loading the bus. (Use I2C -overview)
As the uP cannot communicate with the NVM I2C bus, it spontaneously starts blinking 1-1-1. Note: when there is no access to the NVM, a lot of picture setting can go wrong.
Possible causes:
- V
is shorted (caused by short circuited line transistor 7421), or
BAT
- Sound winding is shorted (amplifier is shortening the power supply lines), or
- D6514 is shorted (due to a too high V
Remove excessive load, to see what causes the failure, or check feedback circuit. See repair tip 'Main Power Supply' (supply needs a minimal load).
is only about 90 V, it is possible that the regulator IC (7506) is defective.
BAT
In case the set does react on a local keyboard operation, you must check the RC-receiver circuitry.
Check RESET-circuitry on diagram B5. Check the level on pin 115 when you switch the set 'on'. Signal must be low initially and go to high after approx. 12 s.
Measure test points on diagram A5.
interruption of the 200 V supply line (e.g. R3341 on circuit F is interrupted).
Re-align the 'focus' potmeter on the Line Output Transformer, or check the SCAVEM circuitry on the CRT-panel (diagram F). It is also possible that the DAF circuitry is defective (see diagram I). Check the Vdc values.
Maybe the crystals 1305 and/or 1308 are making a bad contact.
Investigate whether there is an error code present in the error buffer. In case there is one, check the I2C -bus and/or supply lines (see overview supply lines). Measure and check signal path Tuner-HIP-PICNIC-HOP-RGB amplifier.In case it is a geometry issue, check on diagram A4 opto-coupler 7482, Opamps 7440/7450 and the Frame circuitry alignments or a possible corrupted NVM (7011) on diagram B5.
For most BGA's the pins/balls are ESD protected via diodes to ground, it is possible to measure these diodes with a multi-meter. Overload means no or bad connection.
