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).
4.3.4Small 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-

5.5 Error Codes
5.6 The Blinking LED Procedure
5.7 Protections
5.8 Repair tips
5.1Test 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.
5.2Service 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 %.
– 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.
5.2.2Service 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 MAINTENANCE
– UPGRADE. 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.

5.4ComPair
•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.
5.4.2Specifications
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
5.4.3Stepwise 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.

5.5Error Codes
5.5.1Introduction
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.
5.5.2How 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.
5.5.3How 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.
5.5.4Error 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.
5.6The 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.
5.7Protections
5.7.1Introduction
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.

(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

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.
5.7.5Hardware 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".
5.8Repair tips
5.8.1Miscellaneous
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 20EM5.2E 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!).

Figure 5-4 Start-up circuitry
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.
5.8.4Protections
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.
5.8.5Main 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.
Service Modes, Error Codes, and Fault Finding
EN 21EM5.2E AA5.
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,

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.
