Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
2.1Safety Instructions
Safety regulations require that during a repair:
•Connect the set to the mains via an isolation transformer (>
800 VA).
•Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any other
component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to the
following points:
•Route the wire trees correctly and fix them with the mounted
cable clamps.
•Check the insulation of the mains lead for external damage.
•Check the strain relief of the mains cord for proper function.
•Check the electrical DC resistance between the mains plug
and the secondary side (only for sets which have a mains
isolated power supply):
1. Unplug the mains cord and connect a wire between the
two pins of the mains plug.
2. Set the mains switch to the "on" position (keep the
mains cord unplugged!).
3. Measure the resistance value between the pins of the
AC power plug and the metal shielding of the tuner or
the aerial connection on the set. The reading should be
between 4.5 Mohm and 12 Mohm.
4. Switch "off" the set, and remove the wire between the
two pins of the mains plug.
•Check the cabinet for defects, to avoid touching of any inner
parts by the customer.
2.2Warnings
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling during
repair can reduce life drastically. Make sure that, during
repair, you are connected with the same potential as the
mass of the set by a wristband with resistance. Keep
components and tools also at this same potential. Available
ESD protection equipment:
–Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822
310 10671.
–Wristband tester 4822 344 13999.
•Be careful during measurements in the high voltage section.
•Never replace modules or other components while the unit
is switched "on".
•When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a circuit
becoming unstable.
–Wristband tester 4822 344 13999.
•Never replace modules or other components while the unit
is 'on’.
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode (see chapter 5) with a color 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 (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in standby (F). These values are
indicated by means of the appropriate symbols.
•The 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.
2.3.2Schematic 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=
x10^-6), nano Farads (n= x10^-9), or pico Farads (p= x10^-
12).
•Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
•An "asterisk" (*) indicates component usage varies. Refer to
the diversity tables for the correct values.
•The correct component values are listed in the Electrical
Replacement Parts List. Therefore, always check this list
when there is any doubt.
2.3.3Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
•Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions - reactions that are best avoided. Before reaching
into a powered TV set, it is best to test the high voltage
insulation. It is easy to do, and is a good service precaution.
2.3Notes
2.3.1General
•In order to prevent damage to ICs and transistors, avoid all
high voltage flashovers.
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD, w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this potential. Available ESD
protection equipment:
–Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and ground cable)
4822 310 10671.

Preparation
Do not insert the power plug in a wall socket
before all connections are made.
&
Wall mounting instructions
For the wall mounting instructions follow the
illustrated steps printed on the separate
template. Make sure that the wall mount is
being fixed securely enough so that it meets
safety standards.The weight of the TV (excl.
packaging) is about 87 Lbs. How to mount the
supplied stand, see the separate leaflet.
Note: not supplied stands are optional accessories.
Consult your dealer.éPlace or hang the TV wherever you want,but
make sure that air can circulate freely through
the ventilation slots. Do not install the TV in a
confined space such as a book case or a similar
unit.
To prevent any unsafe situations, no naked
flame sources, such as lighted candles, should
be placed on or in the vicinity.Avoid heat,
direct sunlight and exposure to rain or water.
The equipment shall not be exposed to
dripping or splashing and no objects filled with
liquids, such as vases,shall be placed on it.

In order to obtain the best result, please use
only the supplied aerial cables between the TV
and videorecorder, and between videorecorder
and aerial socket.(Insert the power plug supplied into the mains
at the bottom of the TV and in the wall socket.
Refer to the rear of the TV set for the correct
operation voltage. Consult your local dealer if
your AC power supply is different.To prevent
damaging the power (AC) cord which could
cause a fire or electric shock, do not place the
TV on the cord.

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, this remote is no longer available).
After entering this mode, “SDM” will appear in the upper right
corner of the screen.
How to navigate
When you press the “MENU” button on the RC transmitter, the
set will toggle between the SDM and the normal user menu
(with the SDM mode still active in the background).
How to exit SDM
Use one of the following methods:
•Switch the set to STANDBY via the RC-transmitter.
•Press the “EXIT” button in the DST-emulation feature of
ComPair.
•Via a standard customer RC-transmitter: key in “00”sequence.
5.2.2Service 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 (item 9017) on the
SSP with the indication "SAM". Depending on the software
version, it is possible that a 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
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:
TP11US_1.0_01234 = AAAABB_X.Y_NNNNN).
•AAAA= the chassis name.
EN 18FTP1.1U5.
Service Modes, Error Codes, and Fault Finding
•BB= the region: EU= Europe, AP= Asia Pacific
PAL/Multi, AN= Asia Pacific NTSC, US= USA, LT=
LATAM.
•X.Y= the software version, where X is the main
version number (different numbers are not
compatible with one another) and Y is the sub
version number (a higher number is always
compatible with a lower number).
•NNNNN= last five digits of 12nc code software.
–FBX VERSION (if present).Displays the software
version of the FBX.
–SW VERSION EPLD. Displays the software version of
the EPLD.
•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 recognizes 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 initializing. This will give
the Philips Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
–Initialize 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”.
How to navigate
•In SAM, you can select the menu items with the “CURSOR
UP/DOWN” key on the RC-transmitter. The selected item
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.
5.2.3Customer 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.

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 I2C level. ComPair can access
the I2C bus of the television. ComPair can send and receive
I2C 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 I2C busses of the TV-set.
•Manually (by asking questions to you): Automatic diagnosis
is only possible if the micro controller of the television is
working correctly and only to a certain 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 (only for Europe sets).
•Managing of pre-set lists (only for Europe sets).
•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.
5.4ComPair
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 I2C level) and
is therefore capable of accurately indicating problem areas.
You do not have to know anything about I2C commands
yourself because ComPair takes care of this.
•ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
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 initialization of the television.
In this way, it is possible to distinguish which part of the start-up
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 realized via ComPair and is very helpful when a
protection is activated (see also chapter “Protections”). The
following diagram shows the start-up procedure of the set.
Every step of the stepwise start-up (also called trapped start-up)
in the diagram corresponds with the number of times the led
blinks.

Service Modes, Error Codes, and Fault Finding
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.
5.4.4How 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

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 “I2C”) and the ComPair (or Service) connector at the
rear side of the TV.
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.
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.

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:
•I2C device errors.
•I2C bus errors.
•Protection errors.
•Errors not related to an I2C device, but of importance:
–FALCONIC (ERROR 26): at start-up, after initialization
of the PICNIC, the presence of the FALCONIC can be
checked.
–EAGLE (ERROR 27): at start-up, after initialization of
the PICNIC, the presence of the Eagle can be checked.
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.

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
5.6.1Introduction
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.
5.6.2How 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
5.7.1Introduction
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).
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.

There are several types of protections:
•I2C related protections.
•OTC related protections (via polling on I/O pins or via
algorithms).
•Hardware protection
All protections are explained hereafter.
5.7.2I2C Related Protections
In normal operation, some registers of the I2C controlled ICs are
refreshed every 200 ms. During this sequence, the I2C busses
and the I2C ICs are checked.
An I2C protection will take place if the SDA and SCL lines are
short-circuited to ground, or to each other. An I2C error will also
occur, if the power supply of the IC is missing.
3V3_PDP protection: When the 3V3 supply is short-circuited
or interrupted the set switches off and goes into protection. The
FBX, EPLD IC and 3D comb (US only) have no supply voltage
and give no acknowledge. In this case the set should go into
protection. An error code is written in the NVM: 3V3_PDP error.
FBX protection: the FBX protection is not available anymore.
5.7.3OTC Related Protections

CL 36532053_065.eps

5.7.4Hardware Protection
Short-circuiting the 3V3 supply from the PDP will bring the TV in
protection mode. The absence of the 3V3 supply line is also
sensed via I2C and will be mentioned in the error overview.
5.8Repair tips
5.8.13V3 Supply
As mentioned above, the 3V3 supply is switched “off” when
something goes wrong (detection of a missing 3V3 supply at
one of the devices supplied by the 3V3). Because of this, the set
goes to protection (I2C protection). Error code 55 is logged.
For further diagnoses of the SSP, you need to overrule the I2C
protection: put the set in Service Default Mode by means of the
solder pads on the SSP. Connect an external 3V3 supply at
connector 1Y81 (B20) and make sure the current is limited to
approximately 1200 mA. If the supplied current exceeds 1100
mA (approximately normal working current) you can conclude
that one of the devices supplied by 3V3 is short-circuited on the
SSP. If the current does not exceed 1100mA the supply of the
PDP is defective.
5.8.2ComPair
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. 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.
5.8.3Protections
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 I2C “not-acknowledging” info of FBX + EPLD + 3D
Comb (US) 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.
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 (not used in this set) are initialized 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.
Audio DC protection: The OTC senses if the audio module is
in protection via IRQ-DIGITAL (pin 98 of OTC). If this is the
case, the OTC puts the set in protection.
5.8.4Power Supply
The power supply is part of the PDP display, which is not
described in this manual. However for normal operation at least
+9V-STBY and +9V-STBY-SW must be available, both are
available on connector 1Y82 of SSP. When this is valid the
standby voltage +5V2-DISP must be available otherwise OTC is
not powered.

Or you read the error code sequence via standard remote command

highest priority starting the mentioned blinking.

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.
In case the set does react on a local keyboard operation, you must
check the RC-receiver circuitry (diagram LD).
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-FBX-EPLD.
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.
When no symptom or error code leads you to a specific circuitry, use
the supply lines overview (see supply lines overview), for a quick scan
of all supply lines.

5.9Software Downloading
In this chassis, you can upgrade the “main” software via
ComPair without removing the back cover of the set. The
switch, which is needed for the software downloading
procedure, can be reached through a gap of the back cover.
The switch is located next to the SAM/SDM pads and can be
operated with a long and thin (plastic) screwdriver. Make sure
that you do not damage the PWB with sharp objects. You can
find more information on how this procedure works in the
ComPair file. It is possible that not all sets are equipped with
the hardware, needed to make software upgrading possible. To
speed up the programming process, the firmware IC of the
ComPair interface can be upgraded (every registered customer
receives this IC free of charge)
