To get access to the bottom side (solder side) of the LSP, do the following (see figure above):
1. Remove the DAF-module (see paragraph 'DAF Assy/ Panel' below).
2. To disconnect the degaussing coil from the LSP, remove the cable from connector 1502 (1).
3. Release the wiring from their fixation clamps, in order to get room for repositioning the LSP.
4. Flip the LSP 90 degrees clockwise (2), and place it in the fixation hole at the left side of the bottom tray (3).

4.3.4 Small Signal Board (SSB)

Caution:
Always switch the set completely “OFF” (disconnected the mains cord) before you remove or replace the SSB. As the 5V2 standby voltage is always present (while the set is switched “ON”, in “standby” or in “Protection” mode) on the SIMM connector, it is very risky to remove the SSB in this situation, because the risk of short circuiting is very great.
In fact, there is no predefined service position for the SSB. Most test points are located on the A-side (side that is facing the tuner). If you have to replace ICs, you must take the complete SSB module out of the SIMM-connector. Note: For good access to the A-side, it is necessary to remove the Auto-SCAVEM bracket (at the left side of the SSB). Remove the two fixation screws at the bottom by the Auto-

5.3 Problems and Solving Tips (related to CSM)
5.4 ComPair
5.5 Error Codes
5.6 The Blinking LED Procedure
5.7 Protections
5.8 Repair tips
5.1 Test Points
The chassis is equipped with test points printed on the circuit board assemblies. They refer to the diagram letters.
Perform measurements under the following conditions:
Service Default Mode.
Video: colour 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: In this chassis, two LED configurations are possible: with bicoloured LED (red/green) or with separate blue and red LEDs. The bicoloured version is the one we know from EM5E. The version with blue LED works slightly different. 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
Tuning frequency: 475.25 MHz for PAL/SECAM.
Colour system: SECAM L for France or PAL B/G for the rest of Europe.
All picture settings at 50 % (brightness, colour, contrast).
All sound settings at 50 %, except volume at 25 %.
All service-unfriendly modes (if present) are disabled, like: – (Sleep) timer. – Child/parental lock. –Blue mute. – Automatic volume limiter (AVL).
– Auto switch-off (when no video signal was received for
10 minutes). – Skip/blank of non-favourite pre-sets. – Smart modes. – Auto store of personal presets. – Auto user menu time-out.
How to enter SDM
Use one of the following methods:
Use the standard RC-transmitter and key in the code
"062596", directly followed by the "MENU" button. Note: It is possible that, together with the SDM, the main
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 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 on the DST.
Via a standard customer RC-transmitter: key in "00"- sequence.

5.2.2 Service Alignment Mode (SAM)

Purpose
To perform (software) alignments.
To change option settings.
To easily identify the used software version.
To view operation hours.
To display (or clear) the error code buffer.
Specifications
Operation hours counter.
Software version.
Option settings.
Error buffer reading and erasing.
Software alignments.
How to enter SAM
Use one of the following methods:
Via a standard RC transmitter: key in the code "062596" directly followed by the "OSD [i+]" button. After activating SAM with this method a service warning will appear on the screen, you can continue by pressing any digit key on the RC.
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.
Use the DST-emulation feature of ComPair.
Press the ALIGN button on the DST while the set is in the normal operation
Service Modes, Error Codes, and Fault Finding
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: EM53EU1-1.0_01234 = AAABBC­X.Y_NNNNN).
AAA= the chassis name.
BB= the region: EU= Europe, AP= Asia Pacific
PAL/Multi, AN= Asia Pacific NTSC, US= USA, LT= LATAM.
C= the language cluster number.
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:

Service Modes, Error Codes, and Fault Finding
How to exit SAM
Use one of the following methods:
Press the "MENU" button on the RC-transmitter, or
Switch the set to STANDBY via the RC-transmitter, or
Press the "EXIT" button on the DST.

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.

5.4 ComPair

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. 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.

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.

C commands

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 detected6 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.

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:
2
•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
short-circuited to ground, or to each other. An I occur, if the power supply of the IC is missing (e.g. FBX_PROT (error 16)).

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.

5.7.4 HOP Related Protections

Every 200 ms, the status register of the HOP is read by the OTC (via the I

C bus). If a protection signal is detected on one

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".

5.8 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).
EN 20 EM5.2E AA5.
Service Modes, Error Codes, and Fault Finding
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!).

The start up sequence differs from other sets (e.g. MG-sets or EM2E-sets, but is same as in EM3E-set):
1. When the set is switched "on", the 5 and 8 V lines ("+5V_CON" and "+8V_CON") of the standby power supply are activated.
2. After the OTC senses them, the P will address the HOP via
2
the I
C-bus, to start the drive [1].
3. Via the "SUP-ENABLE" signal, the Main Supply is switched "on" and will deliver the V_BAT to the Line deflection stage [2].
4. EHT generation is now started.
5. The OTC will un-blank the picture.
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).

5.8.6 Standby Supply

The simplest way is to replace the components of the Standby Supply with repair kit 3122 785 90460.

EN 21EM5.2E AA 5.

5.8.7 Line Deflection

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.
To prevent this from happening, you must:

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.

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 standby-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.
