Safety and Maintenance Instructions, Warnings, and Notes
2.Safety and Maintenance Instructions, Warnings, and Notes
EN 5EM6E2.
2.1Safety 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.
•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 MΩ and 12 MΩ.
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.
2.3Warnings
•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
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, symbol 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 ground cable)
4822 310 10671.
– Wristband tester 4822 344 13999.
•Together with the deflection unit and any multi-pole unit,
flat square picture tubes form an integrated unit. The
deflection and the multi-pole units are set optimally at the
factory. 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.

2.2Maintenance 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.
•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.
These values are indicated by means of the appropriate symbols.
2.4Notes
2.4.1General
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (symbol H), or hot ground (symbol
I), depending on the tested area of circuitry.
•The voltages and waveforms shown in the diagrams are
indicative. Measure them in the Service Default Mode (see
chapter 5) with a colour bar signal and stereo sound (L: 3
kHz, R: 1 kHz unless stated otherwise) and picture carrier
at 475.25 MHz (PAL) or 61.25 MHz (NTSC, channel 3).
•Where necessary, measure the waveforms and voltages
with (symbol D) and without (symbol E) aerial signal.
Measure the voltages in the power supply section both in
normal operation (symbol G) and in standby (symbol F).
Page 6
EN 6EM6E2.
Safety and Maintenance Instructions, Warnings, and Notes
•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.
•Manufactured under license from Dolby Laboratories.

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=
-6
x10
), Nano-Farads (n= x10-9), or Pico-Farads (p= x10
•Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
•An 'asterisk' (*) indicates component usage varies. Refer to
the diversity tables for the correct values.
•The correct component values are listed in the Electrical
Replacement Parts List. Therefore, always check this list
when there is any doubt.

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.
).
2.4.3 Rework on BGA ICs (Ball Grid Array)
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, it is essential when
removing an (LF)BGA that the board, tracks, solder lands, or
surrounding components are not damaged. To remove an
(LF)BGA, the board must be uniformly heated to a temperature
close to the reflow soldering temperature. A uniform
temperature reduces the chance of warping the PWB.
To do this, we recommend that the board is heated until it is
certain that all the joints are molten. Then carefully pull the
component off the board with a vacuum nozzle. For the
appropriate temperature profiles, see the IC data sheet.
Area preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA.
Note: Do not apply solder paste, as this has shown to result in
problems during re-soldering.
Device replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF)BGA should be

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, the bi-coloured LED (red/green) is
replaced by two separate LEDs, a blue and a red one. The blue
LED is controlled by software (via ON_OFF_LED). The red
LED will light in anti-phase to the blue, 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.
•Short for a moment the two solder pads on SSP print, with
the indication “SDM”. These solder pads are present at
both sides of the print. Activation can be performed in all
modes, except when the set has a problem with the mainprocessor.
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 entering
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 SSP print, with
the indication SAM. These solder pads are present at both
sides of the print. 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
Page 28
EN 28EM6E5.
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: EM6EU1-
1.0_01234 = AAABBC-X.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.
– SW VERSION RDS RADIO. Displays the software
version of the RDS radio (if RDS radio is present).
•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” sub-
menu.
•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. More info see paragraph Software
downloading.
•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:

will be highlighted. When not all menu items fit on the
screen, move the “CURSOR UP/DOWN” key to display the
next/previous menu items.
•With the “CURSOR LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– Change the value of the selected menu item.
– Activate the selected submenu.
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 menus.

5.4ComPair
5.4.1Introduction
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.
5.4.2Specifications
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
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.

Service Modes, Error Codes, and Fault Finding
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.
In sets with the Muppet IC present (dual screen functionality),
step 2 is skipped.
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.
•Due to the initialisation process of the Muppet IC, step 2 is
not available in sets with Muppet. In this case, step 2 and
3 become one step
5.4.4 How To Connect
1. First, install the ComPair Browser software (see the Quick
Reference Card for installation instructions).
2. Connect the RS232 interface cable between a free serial
(COM) port of your PC and the PC connector (marked with
“PC”) of the ComPair interface.
3. Connect the mains adapter to the supply connector
(marked with “POWER 9V DC”) of the ComPair interface.
4. Switch the ComPair interface “OFF”.
5. Switch the television set “OFF” with the mains switch.
6. Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface
(marked with “I

7. Plug the mains adapter in a mains outlet, and switch the
interface “ON”. The green and red LEDs light up together.
The red LED extinguishes after approx. 1 second while the
green LED remains lit.
8. Start the ComPair program and read the “Introduction”
chapter.
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

code and not the actual cause (e.g., a fault in the protection
detection circuitry can also lead to a protection).
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
There are various errors:
2
•I
C device errors.
2
C bus errors.
•I
•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.
– FALCONIC (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
In case of non-intermittent faults, clear the error buffer before
you begin the repair. This to ensure that old error codes are no
•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.
•Some errors are only for TDL-sets (EM6E AB) or sets with
hard disk.
Extra info for certain errors:
•Error 91: If the TDL microprocessor gets an error from the
LCD display, this will be reported to the OTC, and will log
error 91 (only for TDL sets).
•Error 92: If one of the micro-switches of the LCD display is
not closed within a timeout, the TDL microprocessor will
report an error to the OTC, and error 92 will be logged (only
for TDL sets).
•Error 93: If the 3V3 is not present in DVD mode, or is
present when DVD is in stand-by, error 93 will be logged.
The presence or absence of the supply voltage is detected
via the I/O expander (schematic T3) (only for TDL sets).
•Error 97: There are 2 inputs to generate an error: The IO
expander that checks the supply voltages and the HDD
processor witch controls the hard disk itself. Both generate
the same error: HDD error (only for sets with HDD).
•Error 98: via a control line of the HDD interface IC (7022)
is sensed if the HDD fan is turning. In case the fan is not
turning, the HDD module will be switched off completely
and error 98 will be logged (only for sets with HDD).
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 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
SSP). The blinking 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
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 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
5.7.1 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 SSP, 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
C related protections.
•I
•OTC related protections (via polling on I/O pins or via
algorithms).
•HOP related protections (mainly for deflection items).
•Hardware errors that are not sensed by the OTC (e.g.
In normal operation, some registers of the I
are refreshed every 200 ms. During this sequence, the I
busses and the I

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 protections: 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.

•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
5.7.4 HOP Related Protections
The OTC reads every 200 ms, the status register of the HOP
2
(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.
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 SSP, 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. 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 want to disconnect the SSP,
first disconnect the Mains cord, but keep the Mains Switch “on”.
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!).
TV-set Protection
The following fault conditions will lead to a “complete” set
protection:

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 µP will address the HOP
via the I
2
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 90550.
More detailed way:
1. Replace FET 7504 and zener 6505.
2. Disconnect the SSP 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 Ω 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 90530.
5.8.7 Line Deflection
The simplest way is to replace the components of the Line
Deflection circuitry with repair kit: 3122 785 90330
Caution: item 3400 used in this chassis is different from the
part supplied in the kit. See partlist for correct value and
ordercode.
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:
Interrupt the resistors 3403 and 3404 on the CRT panel
(diagram F1), in order to remove the “filament” voltage from the
tube (no beam current, so no chance of destroying the CRT).
Interrupt resistor 3403 on the LSP (diagram A4) to disable the
“SUP-ENABLE” line.
Measure with a multi-meter, or better with an oscilloscope, the
functionality of the Frame stage.
After you have found the cause, exchange the defective
component (e.g. TDA8177), and re-solder the interrupted
resistors.

5.8.9 Software of HDD module.
Important: It is not possible to replace a HDD by a standard
one (e.g. the ones you can buy in a computer shop), because
it must contain a special boot/application code. The version of
this software can be read out via ComPair, but not in other
service modes like SAM or CSM.
This software is used to boot the HDD module, without this
software on the HDD the module will not boot and the FlexTV
function will not be available.

You have no picture, so: - Read the error buffer via ComPair (error buffer is accessible when set is in protection,
compare-file 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 voltag e and I2C-communication 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-etc
or 18-18-18-etc... 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 I2Coverview)
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_BAT is shorted (caused by short circuited line transistor 7421), or- Sound winding is shorted
(amplifier is shortening the power supply lines), or- D6514 is shorted (due to a too high V_BAT). Remove excessive
load, to see what causes the failure, or check feedback circuit. See repair tip 'Main Power Supply' (supply needs a
minimal load).
In case the set does react on a local keyboard operation, you must check the RC-receiver circuitry (diagram E).
Check RESET-circuitry on diagram B5A. 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.

Re-align the 'FOCUS' potmeter on the Line Output Transformer, or check the SCAVEM circuitry on the CRT-panel

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 B5A.
Check functionality on circuitry (B3a, B3b, and B3c) of PICNIC (7713), FALCONIC (7718, EAGLE (7724) and/or field
memories (7714, 7717, 7719, 7722 and 7723. Tip: the whole Pixel Plus chipset (3 ICs + 5 Field Memories) can be
diagnosed via ComPair.
