Index of this chapter:
3.1 Safety Instructions
3.2 Warnings
3.3 Notes
3.4 Abbreviation List
3.1Safety Instructions
Safety regulations require the following during a repair:
•Connect the set to the Mains/AC Power 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. Of de set
ontploft!
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/AC Power lead for
external damage.
•Check the strain relief of the Mains/AC Power cord for
proper function.
•Check the electrical DC resistance between the Mains/AC
Power plug and the secondary side (only for sets that have
a Mains/AC Power isolated power supply):
1. Unplug the Mains/AC Power cord and connect a wire
between the two pins of the Mains/AC Power plug.
2. Set the Mains/AC Power switch to the “on” position
(keep the Mains/AC Power cord unplugged!).
3. Measure the resistance value between the pins of the
Mains/AC Power plug and the metal shielding of the
tuner or the aerial connection on the set. The reading
should be between 4.5 MΩ and 12 MΩ.
4. Switch “off” the set, and remove the wire between the
two pins of the Mains/AC Power plug.
•Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
picture carrier at 475.25 MHz for PAL, or 61.25 MHz for
NTSC (channel 3).
•Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.
3.3.2Schematic 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 kΩ).
•Resistor values with no multiplier may be indicated with
either an “E” or an “R” (e.g. 220E or 220R indicates 220 Ω).
•All capacitor values are given in micro-farads (μ=× 10
nano-farads (n =× 10
•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 on the Philips
Spare Parts Web Portal.

URL: http://www.atyourservice-magazine.com
“Magazine”, then go to “Repair downloads”. Here you will find
Information on how to deal with BGA-ICs.

Where applicable and available, this profile is added to the IC
Data Sheet information section in this manual.

), or pico-farads (p =× 10
. Select
-12
-6
),
).
3.2Warnings
•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.
•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.
3.3Notes
3.3.1 General
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode with a colour bar signal and stereo
sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and
3.3.5Lead-free Soldering
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin. If lead-free solder paste is
required, please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
•Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able:
– To reach a solder-tip temperature of at least 400°C.
– To stabilize the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.
•Adjust your solder tool so that a temperature of around
360°C - 380°C is reached and stabilized at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
•Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.

3.3.6 Alternative BOM identification
It should be noted that on the European Service website,
“Alternative BOM” is referred to as “Design variant”.
The third digit in the serial number (example:
AG2B0335000001) indicates the number of the alternative
B.O.M. (Bill Of Materials) that has been used for producing the
specific TV set. In general, it is possible that the same TV
model on the market is produced with e.g. two different types
of displays, coming from two different suppliers. This will then
result in sets which have the same CTN (Commercial Type
Number; e.g. 28PW9515/12) but which have a different B.O.M.
number.
By looking at the third digit of the serial number, one can
identify which B.O.M. is used for the TV set he is working with.
If the third digit of the serial number contains the number “1”
(example: AG1B033500001), then the TV set has been
manufactured according to B.O.M. number 1. If the third digit is
a “2” (example: AG2B0335000001), then the set has been
produced according to B.O.M. no. 2. This is important for
ordering the correct spare parts!
For the third digit, the numbers 1...9 and the characters A...Z
can be used, so in total: 9 plus 26= 35 different B.O.M.s can be
indicated by the third digit of the serial number.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 1 and 2 refer to the production centre (e.g.
AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers
to the Service version change code, digits 5 and 6 refer to the
production year, and digits 7 and 8 refer to production week (in
example below it is 2006 week 17). The 6 last digits contain the
serial number.
Figure 3-1 Serial number (example)
3.3.7Board Level Repair (BLR) or Component Level Repair
(CLR)
If a board is defective, consult your repair procedure to decide
if the board has to be exchanged or if it should be repaired on
component level.
If your repair procedure says the board should be exchanged
completely, do not solder on the defective board. Otherwise, it
cannot be returned to the O.E.M. supplier for back charging!
3.3.8 Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
•Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a
powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.

4.2Service Positions
For easy servicing of this set, there are a few possibilities
created:
•The buffers from the packaging.
•Foam bars (created for Service).
4.2.1 Foam Bars
4.3.3Ambi Light
Each Ambi Light unit is mounted on a subframe. Refer to
Figure 4-5
for details.
Figure 4-4 Foam bars
The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs.
See Figure 4-4
for details. Sets with a display of 42" and larger,
require four foam bars [1]. Ensure that the foam bars are
always supporting the cabinet and never only the display.
Caution: Failure to follow these guidelines can seriously
damage the display!
By laying the TV face down on the (ESD protective) foam bars,
a stable situation is created to perform measurements and
alignments. By placing a mirror under the TV, you can monitor
the screen.

5.1Test Points
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. However, several key
ICs are capable of generating test patterns, which can be
controlled via ComPair. In this way it is possible to determine
which part is defective.
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) offers several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
(see also section “5.4.1 ComPair
”).
•All service-unfriendly modes (if present) are disabled, like:
– (Sleep) timer.
– Child/parental lock.
– Picture mute (blue mute or black mute).
– Automatic volume levelling (AVL).
– Skip/blank of non-favourite pre-sets.
How to Activate SDM
For this chassis there are two kinds of SDM: an analog SDM
and a digital SDM. Tuning will happen according Table 5-1
•AnalogSDM: use the standard RC-transmitter and key in
the code “062596”, directly followed by the “MENU” (or
HOME) button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it “off”, push the “MENU”(or
HOME) button again.
•DigitalSDM: use the standard RC-transmitter and key in
the code “062593”, directly followed by the “MENU” (or
HOME) button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it “off”, push the “MENU” (or
HOME) button again.
•AnalogSDM can also be activated by grounding for a
moment the solder pad on the SSB, with the indication
“SDM” (see Service mode pad
).
.
Note: For the new model range, a new remote control (RC) is
used with some renamed buttons. This has an impact on the
activation of the Service modes. For instance the old “MENU”
button is now called “HOME” (or is indicated by a “house” icon).
5.2.1Service 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 detected by stand-by
processor and make the TV start up to the step just before
protection (a sort of automatic stepwise start-up). See
section “5.3 Stepwise Start-up
•To start the blinking LED procedure where only LAYER 2
errors are displayed. (see also section “5.5 Error Codes

How to Navigate
When the “MENU” (or HOME) button is pressed on the RC
transmitter, the TV set will toggle between the SDM and the
normal user menu.
How to Exit SDM
Use one of the following methods:
•Switch the set to STAND-BY via the RC-transmitter.
•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.

How to Activate SAM
Via a standard RC transmitter: Key in the code “062596”
directly followed by the “INFO” button. After activating SAM
with this method a service warning will appear on the screen,
continue by pressing the “OK” button on the RC.
Contents of SAM (see also Table 6-4
)
•Hardware Info.
– A. SW Version. Displays the software version of the
main software (example: Q5492-1.2.3.4 =
AAAAB_X.Y.W.Z).
•AAAA= the chassis name.
•B= the SW branch version. This is a sequential
number (this is no longer the region indication, as
the software is now multi-region).
•X.Y.W.Z= the software version, where X is the
main version number (different numbers are not
compatible with one another) and Y.W.Z is the sub
version number (a higher number is always
compatible with a lower number).
– B. STBY PROC Version. Displays the software
version of the stand-by processor.
– C. Production Code. Displays the production code of
the TV, this is the serial number as printed on the back
of the TV set. Note that if an NVM is replaced or is
initialized after corruption, this production code has to
be re-written to NVM. ComPair will foresee in a
possibility to do this.
•Operation Hours. Displays the accumulated total of
operation hours (not the stand-by hours). Every time the
TV is switched “on/off”, 0.5 hours is added to this number.
•Errors (followed by maximum 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see section “5.5 Error Codes
”).
•Reset Error Buffer. When “cursor right” (or the “OK
button) is pressed and then the “OK” button is pressed, the
error buffer is reset.
•Alignments. This will activate the “ALIGNMENTS” submenu. See Chapter 6. Alignments.
•Dealer Options. Extra features for the dealers.
•Options. Extra features for Service. For more info
regarding option codes, 6. Alignments
.
Note that if the option code numbers are changed, these
have to be confirmed with pressing the “OK” button before
the options are stored. Otherwise changes will be lost.
•Initialize NVM. The moment the processor recognizes a
corrupted NVM, the “initialize NVM” line will be highlighted.
Now, two things can be done (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 Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
– Initialize the NVM.
Note: When the NVM is corrupted, or replaced, there is a high
possibility that no picture appears because the display code is
not correct. So, before initializing the NVM via the SAM, a
picture is necessary and therefore the correct display option
has to be entered. Refer to Chapter 6. Alignments
for details.
To adapt this option, it’s advised to use ComPair (the correct
HEX values for the options can be found in Chapter 6.
Alignments) or a method via a standard RC (described below).
Changing the display option via a standard RC: Key in the
code “062598” directly followed by the “MENU” (or HOME)
button and “XXX” (where XXX is the 3 digit decimal display
code as mentioned in Table 6-3
digits, also the leading zero’s. If the above action is successful,
the front LED will go out as an indication that the RC sequence
). Make sure to key in all three
was correct. After the display option is changed in the NVM, the
TV will go to the Stand-by mode. If the NVM was corrupted or
empty before this action, it will be initialized first (loaded with
default values). This initializing can take up to 20 seconds.
Figure 5-2 Location of Display Option Code sticker
•Store - go right. All options and alignments are stored
when pressing “cursor right” (or the “OK” button) and then
the “OK”-button.
•SW Maintenance.
– SW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
– HW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
•Operation hours display. Displays the accumulated total
of display operation hours. So, this one keeps up the
lifetime of the display itself, mainly to compensate the
degeneration behaviour.
•Test settings. For development purposes only.
•Development file versions. Not useful for Service
purposes, this information is only used by the development
department.
•Upload to USB. To upload several settings from the TV to
an USB stick, which is connected to the SSB. The items are
“Channel list”, “Personal settings”, “Option codes”,
“Display-related alignments” and “History list”. First a
directory “repair\” has to be created in the root of the
USB stick. To upload the settings select each item
separately, press “cursor right” (or the “OK” button),
confirm with “OK” and wait until “Done” appears. In case
the download to the USB stick was not successful “Failure”
will appear. In this case, check if the USB stick is
connected properly and if the directory “repair” is present in
the root of the USB stick. Now the settings are stored onto
the USB stick and can be used to download onto another
TV or other SSB. Uploading is of course only possible if the
software is running and if a picture is available. This
method is created to be able to save the customer’s TV
settings and to store them into another SSB.
•Download to USB. To download several settings from the
USB stick to the TV, same way of working needs to be
followed as with uploading. To make sure that the
download of the channel list from USB to the TV is
executed properly, it is necessary to restart the TV and
tune to a valid preset if necessary.
Note: The “History list item” can not be downloaded from
USB to the TV. This is a “read-only” item. In case of
specific problems, the development department can ask
for this info.
How to Navigate
•In SAM, the menu items can be selected 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.
– (De) activate the selected sub menu.
Page 17
Service Modes, Error Codes, and Fault Finding
EN 17Q549.2E LA5.
•With the “OK” key, it is possible to activate the selected
action.
How to Exit SAM
Use one of the following methods:
•Switch the TV set to STAND-BY via the RC-transmitter.
•Via a standard RC-transmitter, key in “00” sequence, or
select the “BACK” key.
5.2.3 Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer or the Customer Helpdesk. The service
technician can then 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.
When in this chassis CSM is activated, a testpattern will be
displayed during 5 seconds (1 second Blue, 1 second Green
and 1 second Red, then again 1 second Blue and 1 second
Green). This test pattern is generated by the PNX5100. So if
this test pattern is shown, it could be determined that the back
end video chain (PNX5100, LVDS, and display) of the SSB is
working.
When CSM is activated and there is a USB stick connected to
the TV, the software will dump the complete CSM content to the
USB stick. The file (Csm.txt) will be saved in the root of the USB
stick. This info can be handy if no information is displayed.
Also when CSM is activated, the LAYER 1 error is displayed via
blinking LED. Only the latest error is displayed. (see also
section 5.5 Error Codes
How to Activate CSM
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, can be navigated through the menus.

Service Modes, Error Codes, and Fault Finding
5.3Stepwise Start-up
When the TV is in a protection state due to an error detected by
stand-by software (error blinking is displayed) and SDM is
activated via shortcutting the pins on the SSB, the TV starts up
until it reaches the situation just before protection. So, this is a
kind of automatic stepwise start-up. In combination with the
start-up diagrams below, you can see which supplies are
present at a certain moment. Important to know is, that if e.g.
the 3V3 detection fails and thus error layer 2 = 18 is blinking
while the TV is restarted via SDM, the Stand-by Processor will
enable the 3V3, but the TV set will not go to protection now.
The TV will stay in this situation until it is reset (Mains/AC
Power supply interrupted). Caution: in case the start-up in this
mode with a faulty FET 7U08 is done, you can destroy all IC’s
supplied by the +3V3, due to overvoltage (12V on 3V3-line). It
is recommended to measure first the FET 7U08 or others
FET’s on shortcircuit before activating SDM via the service
pads.
The abbreviations “SP” and “MP” in the figures stand for:
•SP: protection or error detected by the Stand-by Processor.
•MP: protection or error detected by the MIPS Main Processor.

5.4Service Tools
5.4.1 ComPair
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:
1. ComPair helps to quickly get an understanding on how to
repair the chassis in a short and effective way.
2. ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. No
knowledge on I
because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the uP
is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The ComPair II interface box is connected to the PC via an
USB cable. For the TV chassis, the ComPair interface box and
the TV communicate via a bi-directional cable via the service
connector(s).
The ComPair fault finding program is able to determine the
problem of the defective television, by a combination of
automatic diagnostics and an interactive question/answer
procedure.
How to Connect
This is described in the chassis fault finding database in
ComPair.

Caution: It is compulsory to connect the TV to the PC as
shown in the picture above (with the ComPair interface in
between), as the ComPair interface acts as a level shifter. If
one connects the TV directly to the PC (via UART), ICs will be
blown!

5.4.2Memory and Audio Test
With this tool you can test the memory of the PNX8543, as well
if the PNX5100 is enabled and audio-testing.
What is needed?
– An USB-stick
– “TESTSCRIPT Q549”. Downloadable from the Philips
Service website from the section “Software for Service
only”
– A ComPair/service cable (3138 188 75051).
Procedure
Create a directory “JETTFILES” under the root of the USB-stick
– Place “MemTestTV543.bin” and “autojett.bin” (available in
“TESTSCRIPT Q549”) under the directory “JETTFILES”
– Install the computer program “BOARDTESTLOGGER”
(available in “TESTSCRIPT Q549”) on the PC
– Connect a “ComPair/service”-cable from the service-
connector in the set, into the “multi function” jack at the
front of the ComPair II box :
Required settings in ComPair :
- start up the ComPair application.
- Select the correct database (open file “Q549.2E LA”, this
will set the ComPair interface in the appropriate mode).
- Close ComPair
– Start up the program “BOARDTESTLOGGER” and select
“COMx”
– Put the USB stick into the TV and start up the TV while
pressing the “i+”-button on a Philips DVD RC6 remote
control (it’s also possible to use a TV remote in “DVD”mode)
– On the PC the memory test is shown now. This is also
visible on the TV screen.
– In “BOARDTESTLOGGER” an option “Send extra UART
command” can be found where you can select “AUD1”.
This command generates hear test tones of 200, 400,
1000, 2 000, 3 000, 5 000, 8 000 and 12 500Hz.
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 occurs, it is added to the list of errors, provided
the list is not full. 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).
To prevent that an occasional error stays in the list forever, the
error is removed from the list after more than 50 hrs. of
operation.
When multiple errors occur (errors occurred within a short time
span), there is a high probability that there is some relation
between them.
New in this chassis is the way errors can be displayed:
•There is a simple blinking LED procedure for board level
repair (home repair) so called LAYER 1 errors next to the
existing errors which are LAYER 2 errors (see Table 5-2
– LAYER 1 errors are one digit errors.
– LAYER 2 errors are 2 digit errors.
•In protection mode.
– From consumer mode: LAYER 1.
– From SDM mode: LAYER 2.
•Fatal errors, if I2C bus is blocked and the set reboots,
CSM and SAM are not selectable.
– From consumer mode: LAYER 1.
– From SDM mode: LAYER 2.
Important remark:
).
2009-May-08

EN 28Q549.2E LA5.
Service Modes, Error Codes, and Fault Finding
For all errors detected by MIPS which are fatal =>
rebooting of the TV set (reboot starts after LAYER 1
error blinking), one should short the solder paths
(SDM) at start-up from the power OFF state by mains
interruption and not via the power button to trigger the
SDM via the hardware pins.
•In CSM mode
– When entering CSM: error LAYER 1 will be displayed
by blinking LED. Only the latest error is shown.
•In SDM mode
– When SDM is entered via Remote Control code or the
hardware pins, LAYER 2 is displayed via blinking LED.
•In the ON state
– In “Display error mode”, set with the RC commands
“mute_06250X _OK” LAYER 2 errors are displayed via
blinking LED.
•Error display on screen.
– In CSM no error codes are displayed on screen.
– In SAM the complete error list is shown.
Basically there are three kinds of errors:
•Errors detected by the Stand-by software which lead to protection. These errors will always lead to protection and
an automatic start of the blinking LED LAYER 1 error.
(see section “5.6 The Blinking LED Procedure
•Errors detected by the Stand-by software which not lead to protection. In this case the front LED should blink
the involved error. See also section “5.5 Error Codes
Error Buffer, Extra Info”. Note that it can take up several
minutes before the TV starts blinking the error (e.g. LAYER
1 error = 2, LAYER 2 error = 15 or 53).
•Errors detected by main software (MIPS). In this case
the error will be logged into the error buffer and can be read
out via ComPair, via blinking LED method LAYER 1-2
error, or in case picture is visible, via SAM.
”).
, 5.5.4
•Via polling on I/O pins going to the stand-by processor.
•Via sensing of analog values on the stand-by processor or
the PNX8543.
•Via a “not acknowledge” of an I
Take notice that some errors need several minutes before they
start blinking or before they will be logged. So in case of
problems wait 2 minutes from start-up onwards, and then
check if the front LED is blinking or if an error is logged.

C communication.
5.5.2 How to Read the Error Buffer
Use one of the following methods:
•On screen via the SAM (only when a picture is visible).
E.g.:
– 00 00 00 00 00: No errors detected
– 23 00 00 00 00: Error code 23 is the last and only
detected error.
– 37 23 00 00 00: Error code 23 was first detected and
error code 37 is the last detected error.
– Note that no protection errors can be logged in the
error buffer.
•Via the blinking LED procedure. See section 5.5.3 How to
Clear the Error Buffer.
•Via ComPair.
5.5.3 How to Clear the Error Buffer
Use one of the following methods:
•By activation of the “RESET ERROR BUFFER” command
in the SAM menu.
•With a normal RC, key in sequence “MUTE” followed by
“062599” and “OK”.
•If the content of the error buffer has not changed for 50+
hours, it resets automatically.
5.5.4 Error Buffer
In case of non-intermittent faults, clear the error buffer before
starting to repair (before clearing the buffer, write down the
content, as this history can give significant information). This to
ensure that old error codes are no longer present.
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 several mechanisms of error detection:
•Via error bits in the status registers of ICs.

•Rebooting. When a TV is constantly rebooting due to
internal problems, most of the time no errors will be logged
or blinked. This rebooting can be recognized via a ComPair
interface and Hyperterminal (for Hyperterminal settings,
see section “5.8 Fault Finding and Repair Tips
, 5.8.6
Logging). It’s shown that the loggings which are generated
by the main software keep continuing. In this case
diagnose has to be done via ComPair.
•Error 13 (I
2
C bus 3 blocked). At the time of release of this
manual, this error was not working as expected. Current
situation: when this error occurs, the TV will constantly
reboot due to the blocked bus. The best way for further
diagnosis here, is to use ComPair.
•Error 15 (PNX8543,PNX5100 doesn’t boot). Indicates
that the main processor/PNX5100 was not able to read his
bootscript. This error will point to a hardware problem
around the PNX8543 (supplies not OK, PNX 8543
completely dead, I
Processor broken, etc...). When error 15 occurs it is also
possible that I
2
C link between PNX and Stand-by
2
C1 bus is blocked (NVM). I2C1 can be
indicated in the schematics as follows: SCL-UP-MIPS,
SDA-UP-MIPS, SCL-1, SDA-1, SCL-2 or SDA-2.
Other root causes for this error can be due to hardware
problems from the NVM PNX5100, DDR’s and the
bootscript reading from the PNX5100.
•Error 16 (12V). This voltage is made in the power supply
and results in protection (LAYER 1 error = 3) in case of
absence. When SDM is activated we see blinking LED
LAYER 2 error = 16.
•Error 17 (Invertor or Display Supply). Here the status of
the “Power OK” is checked by software, no protection will
occur during failure of the invertor or display supply (no
picture), only error logging. LED blinking of LAYER 1
error = 3 in CSM, in SDM this gives LAYER 2 error = 17.
•Error 18 (1V2-3V3-5V too low). All these supplies are
generated by the DC/DC supply on the SSB. If one of these
supplies is too low, protection occurs and blinking LED
LAYER 1 error = 2 will be displayed automatically. In SDM
this gives LAYER 2 error = 18.
•Error 21 (PNX 5100). When there is no I
2
C communication
towards the PNX5100, the TV set will start rebooting and
display LAYER 1 error = 2. Disconnect the mains cord now
and start up the TV set with the solder path (SDM) short to
ground during start-up to activate the LAYER 2 error
blinking. Error “21” will be logged and displayed via the
blinking LED procedure after a few moments from start-up.
Remark : the rebooting can be recognized via a ComPair
interface and Hyperterminal (for Hyperterminal settings,
see section “5.8 Fault Finding and Repair Tips

5.6The Blinking LED Procedure
5.6.1Introduction
The blinking LED procedure can be split up into two situations:
•Blinking LED procedure LAYER 1 error. In this case the
error is automatically blinked when the TV is put in CSM.
This will be only one digit error, namely the one that is
referring to the defective board (see table “5-2 Error code
overview”) which causes the failure of the TV. This
approach will especially be used for home repair and call
centres. The aim here is to have service diagnosis from a
distance.
•Blinking LED procedure LAYER 2 error. Via this procedure,
the contents of the error buffer can be made visible via the
front LED. In this case the error contains 2 digits (see table
“5-2 Error code overview
(hardware pins) is activated. This is especially useful for
fault finding and gives more details regarding the failure of
the defective board.
Important remark:
For all errors detected by MIPS which are fatal => rebooting of
the TV set (reboot starts after LAYER 1 error blinking), one
should short the solder paths at start-up from the power OFF
state by mains interruption and not via the power button to
trigger the SDM via the hardware pins.
When one of the blinking LED procedures is activated, the front
LED will show (blink) the contents of the error buffer. Error
codes greater then 10 are shown as follows:
1. “n” long blinks (where “n” = 1 to 9) indicating decimal digit
2. A pause of 1.5 s
3. “n” short blinks (where “n”= 1 to 9)
4. A pause of approximately 3 s,
5. When all the error codes are displayed, the sequence
finishes with a LED blink of 3 s
6. The sequence starts again.
Example: Error 12 8 6 0 0.
After activation of the SDM, the front LED will show:
1. One long blink of 750 ms (which is an indication of the
decimal digit) followed by a pause of 1.5 s
2. Two short blinks of 250 ms followed by a pause of 3 s
3. Eight short blinks followed by a pause of 3 s
4. Six short blinks followed by a pause of 3 s
5. One long blink of 3 s to finish the sequence
6. The sequence starts again.
”) and will be displayed when SDM
2
C controlled
•Activate the CSM. The blinking front LED will show only
the latest layer 1 error, this works in “normal operation”
mode or automatically when the error/protection is
monitored by the standby processor.
In case no picture is shown and there is no LED blinking,
read the logging to detect whether “error devices” are
mentioned. (see section “5.8 Fault Finding and Repair
Tips, 5.8.6 Logging”).
•Activate the SDM. The blinking front LED will show the
entire content of the LAYER 2 error buffer, this works in
“normal operation” mode or when SDM (via hardware pins)
is activated when the tv set is in protection.
Important remark:
For all errors detected by MIPS which are fatal =>
rebooting of the TV set (reboot starts after LAYER 1 error
blinking), one should short the solder paths at start-up from
the power OFF state by mains interruption and not via the
power button to trigger the SDM via the hardware pins.
•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.
5.7Protections
5.7.1Software Protections
Most of the protections and errors use either the stand-by
microprocessor or the MIPS controller as detection device.
Since in these cases, checking of observers, polling of ADCs,
and filtering of input values are all heavily software based,
these protections are referred to as software protections.
There are several types of software related protections, solving
a variety of fault conditions:
•Protections related to supplies: check of the 12V, +5V,
+3V3 and 1V2.
•Protections related to breakdown of the safety check mechanism. E.g. since the protection detections are done
by means of software, failing of the software will have to
initiate a protection mode since safety cannot be
guaranteed any more.
Remark on the Supply Errors
The detection of a supply dip or supply loss during the normal
playing of the set does not lead to a protection, but to a cold
reboot of the set. If the supply is still missing after the reboot,
the TV will go to protection.
Protections during Start-up
During TV start-up, some voltages and IC observers are
actively monitored to be able to optimise the start-up speed,
and to assure good operation of all components. If these
monitors do not respond in a defined way, this indicates a
malfunction of the system and leads to a protection. As the
observers are only used during start-up, they are described in
the start-up flow in detail (see section “5.3 Stepwise Start-up
5.7.2Hardware Protections
The only real hardware protection in this chassis appears in
case of an audio problem e.g. DC voltage on the speakers. This
protection will only affect the Class D (7D10) and puts the
amplifier in a continuous burst mode (cyclus approximately 2
seconds).
”).
5.6.2How to Activate
Use one of the following methods:

loudspeakers will move slowly in one or the other direction
until the initial failure shuts the amplifier down, this cyclus
starts over and over again.
5.7.3Important remark regarding the blinking LED indication
As for the blinking LED indication, the blinking led of LAYER 1
error displaying can be switched off by pushing the power
button on the keyboard.
This condition is not valid after the set was unpowered (via
mains interruption). The blinking LED starts again and can only
be switched off by unplugging the mains connection.
This can be explained by the fact that the MIPS can not load
the keyboard functionality from software during the start-up and
doesn’t recognizes the keyboard commands at this time.

Info”.
5.8.1Ambilight
Due to degeneration process of the AmbiLights, there can be a
difference in the colour and/or light output of the spare
ambilight module in comparison with the originals ones
contained in the TV set. Via ComPair the light output can be
adjusted.
5.8.2Audio Amplifier
The Class D-IC 7D10 has a powerpad for cooling. When the IC
is replaced it must be ensured that the powerpad is very well
pushed to the PWB while the solder is still liquid. This is needed
to insure that the cooling is guaranteed, otherwise the Class DIC could break down in short time.
started immediately when +12V incoming voltage is available
(+12V is enabled by STANDBY signal, active low). Supply
voltages +3V3, 2V5, +1V8-PNX5100, +1V8-PNX85XX, +5V
and +5V-TUN are switched-on directly by signal ENABLE-3V3
(active low), provided that +12V (detected via 7U40 &7U41) is
available. +12V is considered OK (=> DETECT -12V signal
becomes high and 12V/3V3 and 12V/5V DC-DC converter can
be started up) if it rises above 10V5 (typical) and doesn’t drop
below 10V (typical).
Debugging
The best way to find a failure in the DC/DC converters is to
check their start-up sequence at power-on via the mains cord,
presuming that the standby microprocessor and the external
supply are operational. Take STANDBY signal high-to-low
transition as time reference.
When +12V becomes available (maximum 1 second after
STANDBY signal goes low) then +1V2-PNX85XX and +1V2PNX5100 are started immediately. Then, after ENABLE-3V3
goes low, all the other supply voltages should rise within 2ms.
Tips
•When an output supply voltage is short-circuited to GND
the corresponding DC-DC converter is not
audible noise, the converter switches-off immediately and
will attempt a re-start only after +12V drops and rises
again.
•Check the integrity (at least no short-circuit between drain
and source) of power MOS-FETs, especially the high-side
ones: 7U05, 7U08, 7U0D-1 and 7U0H-1 before starting the
platform in SDM mode, otherwise it can be easily
damaged.
•Switching frequency of DC-DC converters should be
around 290KHz for 12V to 1V2 DC-DC converters and
around 370KHz for 12V to 3V3 and 12V to 5V DC-DC
converters.

5.8.3 CSM
When CSM is activated and there is a USB stick connected to
the TV, the software will dump the complete CSM content to the
USB stick. The file (Csm.txt) will be saved in the root of the USB
stick. If this mechanism works it can be concluded that a large
part of the operating system is already working (MIPS, USB...)
5.8.4 DC/DC Converter
Description
The onboard supply consists of 5 DC/DC converters and 4
linear stabilizers. All DC/DC converters have +12V input
voltage and deliver :
•+1V2-PNX85XX supply voltage (1.24V nominal), stabilized
close to PNX8543 chip.
•+1V2-PNX5120 supply voltage (1.26V nominal), stabilized
close to PNX5120 chip.
•+3V3 (3.34V nominal, overall 3.3 V for onboard IC’s).
•+5V (5.15V nominal) for USB and Conditional Access
Interface and +5V5-TUN for +5V-TUN tuner stabilizer.
•+33VTUN (34V nominal) for analog-only tuners.
The linear stabilizers are providing:
•+1V2-STANDBY (out of +3V3-STANDBY), 1.24V nominal.
•+1V8-PNX85XX and +1V8PNX5100 (connected via
CFH1), 1.84V nominal.
•+2V5 (WOW FPGA diversity only), 2.5V nominal.
•+5V-TUN (out of +5V5-TUN), 5V nominal.
+3V3-STANDY and +1V2-STANDBY are permanent voltages.
Supply voltages +1V2-PNX85XX and +1V2-PNX5100 are
When an “F” is displayed in the screen’s right corner, this
means the set is in “Factory” mode, and it normally
happens after a new SSB is mounted. To exit this mode, push
the “VOLUME minus” button on the TV’s local keyboard for 10
seconds (this disables the continuous mode).
Then push the “SOURCE” button for 10 seconds until the “F”
disappears from the screen.
5.8.6Logging
When something is wrong with the TV set (f.i.the set is
rebooting) you can check for more information via the logging
in Hyperterminal. The Hyperterminal is available in every
Windows application via Programs, Accessories,
Communications, Hyperterminal. Connect a “ComPair UART”cable (3138 188 75051) from the service connector in the TV to
the “multi function” jack at the front of ComPair II box.
Required settings in ComPair before starting to log :
- Start up the ComPair application.
- Select the correct database (open file “Q549.2E LA”, this will
set the ComPair interface in the appropriate mode).
- Close ComPair
After start-up of the Hyperterminal, fill in a name (f.i. “logging”)
in the “Connection Description” box, then apply the following
settings:
1. COMx
2. Bits per second = 115200
3. Data bits = 8
4. Parity = none
5. Stop bits = 1
6. Flow control = none
During the start-up of the TV set, the logging will be displayed.
This is also the case during rebooting of the TV set (the same
logging appears time after time). Also available in the logging
is the “Display Option Code” (useful when there is no picture),

look for item “DisplayRawNumber” in the beginning of the
logging. Tip: when there is no picture available during rebooting
you are able to check for “error devices” in the logging (LAYER
2 error) which can be very helpful to determine the failure cause
of the reboot. For protection state, there is no logging.
5.8.7Loudspeakers
Make sure that the volume is set to minimum during
disconnecting the speakers in the ON-state of the TV. The
audio amplifier can be damaged by disconnecting the speakers
during ON-state of the set!
5.8.8 IPB
In case of no picture when CSM-test pattern from PNX5100 is
activated and backlight doesn’t light up, it’s recommended first
to check the inverter on the IPB + wiring (LAYER 2 error = 17
is displayed in SDM).
5.8.9Tuner
Attention: In case the tuner is replaced, always check the tuner
options!

The EDID MUX device (including all HDMI NVM except the 4th)
is upgradeable via USB, see ComPair for further instructions. It
should be noted that in case a new spare EDID MUX device is
used for repair, the initial default address must be changed
from “C0” to “CE”, to be done via ComPair.
5.8.13 Upgrade VGA/4th HDMI EDID NVM
To prevent damage on the coax wires, especially the female
core of the coax wires (can be bend over during dis- and
reconnecting), this should be carried out by use of pliers.

5.9Software Upgrading
5.9.1Introduction
The set software and security keys are stored in a NANDFlash, which is connected to the PNX8543 via the PCI bus.
It is possible for the user to upgrade the main software via the
USB port. This allows replacement of a software image in a
stand alone set, without the need of an E-JTAG debugger. A
description on how to upgrade the main software can be found
in the DFU.
Important: When the NAND-Flash must be replaced, a new
SSB must be ordered, due to the presence of the security keys!
(copy protection keys, MAC address, ...).
Perform the following actions after SSB replacement:
1. Set the correct option codes (see sticker inside the TV).
2. Update the TV software => see the eUM (electronic User
Manual) for instructions.
3. Perform the alignments as described in chapter 6 (section
6.5 Reset of Repaired SSB
4. Check in CSM if the HDMI key, MAC address.. are valid.
For the correct order number of a new SSB, always refer to the
Spare Parts list!
5.9.2 Main Software Upgrade
•The “UpgradeAll.upg” file is only used in the factory.
•The “FlashUtils.upg” file is only used by service centra
which are allowed to do component level repair on the
SSB.
Automatic Software Upgrade
In “normal” conditions, so when there is no major problem with
the TV, the main software and the default software upgrade
application can be upgraded with the “AUTORUN.UPG”
(FUS part of the one-zip file: e.g. 3104 337 05661 _FUS
_Q5492_ 1.26.15.0_commercial.zip). This can also be done by
the consumers themselves, but they will have to get their
software from the commercial Philips website or via the
Software Update Assistant in the user menu (see eUM). The
“autorun.upg” file must be placed in the root of the USB stick.
How to upgrade:
1. Copy “AUTORUN.UPG” to the root of the USB stick.
2. Insert USB stick in the set while the set is in ON MODE.
The set will restart and the upgrading will start
automatically. As soon as the programming is finished, a
message is shown to remove the USB stick and restart the
set.
Manual Software Upgrade
In case that the software upgrade application does not start
automatically, it can also be started manually.
How to start the software upgrade application manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the “OK” button on a Philips TV remote control or a
Philips DVD RC-6 remote control (it is also possible to use
a TV remote in “DVD” mode). Keep the “OK” button
pressed while reconnecting the TV to the Mains/AC Power.
3. The software upgrade application will start.
Attention!
In case the download application has been started manually,
the “autorun.upg” will maybe not be recognized.
What to do in this case:
1. Create a directory “UPGRADES” on the USB stick.
2. Rename the “autorun.upg” to something else, e.g. to
“software.upg”. Do not use long or complicated names,
keep it simple. Make sure that “AUTORUN.UPG” is no
longer present in the root of the USB stick.
3. Copy the renamed “upg” file into this directory.
4. Insert USB stick into the TV.
).
5. The renamed “upg” file will be visible and selectable in the
upgrade application.
Back-up Software Upgrade Application
If the default software upgrade application does not start (could
be due to a corrupted boot 2 sector) via the above described
method, try activating the “back-up software upgrade
application”.
How to start the “back-up software upgrade application”
manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the “INFO”-button on a Philips remote control or
“CURSOR DOWN” button on a Philips DVD RC-6 remote
control (it is also possible to use a TV remote in “DVD”
mode). Keep the “INFO”-button (or “cursor down” button)
pressed while reconnecting the TV to the Mains/AC Power.
3. The software upgrade application will start.
5.9.3Stand-by Software Upgrade via USB
In this chassis it is possible to upgrade the Stand-by software
via a USB stick. The method is similar to upgrading the main
software via USB.
Use the following steps:
1. Create a directory “UPGRADES” on the USB stick.
2. Copy the Stand-by software (part of the one-zip file, e.g.
StandbySW_CFT72_88.0.0.0.upg) into this directory.
3. Insert the USB stick into the TV.
4. Start the download application manually (see section “
Manual Software Upgrade”.
5. Select the appropriate file and press the “OK” button to
upgrade.

•Connect the set to the mains via an isolation transformer
with low internal resistance.
•Allow the set to warm up for approximately 15 minutes.
•Measure voltages and waveforms in relation to correct
ground (e.g. measure audio signals in relation to
AUDIO_GND).
Caution: It is not allowed to use heat sinks as ground.
•Test probe: Ri > 10 MΩ, Ci < 20 pF.
•Use an isolated trimmer/screwdriver to perform
alignments.
6.1.1Alignment Sequence
•First, set the correct options:
– In SAM, select “Options”, and then “Option numbers”.
– Fill in the option settings for “Group 1” and “Group 2”
according to the set sticker (see also paragraph 6.4
Option Settings).
– Press OK on the remote control before the cursor is
moved to the left.
– In submenu “Option numbers” select “Store” and press
OK on the RC.
•OR:
– In main menu, select “Store” again and press OK on
the RC.
– Switch the set to Stand-by.
•Warming up (>15 minutes).
6.2Hardware Alignments
Not applicable.
6.3Software Alignments
Put the set in SAM mode (see Chapter 5. Service Modes, Error
Codes, and Fault Finding). The SAM menu will now appear on
the screen. Select ALIGNMENTS and go to one of the sub
menus. The alignments are explained below.
The following items can be aligned:
•Tuner AGC.
•White point.
To store the data:
•Press OK on the RC before the cursor is moved to the left.
•In main menu select “Store” and press OK on the RC.
•Press MENU on the RC to switch back to the main menu.
•Switch the set to stand-by mode.
For the next alignments, supply the following test signals via a
video generator to the RF input:
•EU/AP-PAL models: a PAL B/G TV-signal with a signal
strength of at least 1 mV and a frequency of 475.25 MHz
•US/AP-NTSC models: an NTSC M/N TV-signal with a
signal strength of at least 1 mV and a frequency of 61.25
MHz (channel 3).
•LATAM models: an NTSC M TV-signal with a signal
strength of at least 1 mV and a frequency of 61.25 MHz
(channel 3).
6.3.1Tuner AGC (RF AGC Take Over Point Adjustment)
Purpose: To keep the tuner output signal constant as the input
signal amplitude varies.
No alignment is necessary, for the AGC alignment you can use
the default value : “80”.
Store settings and exit SAM.
6.3.2White Point
•Set “Active control” to “Off”.
•Choose “TV menu”, “TV Settings” and then “Picture” and
set picture settings as follows:
Picture Setting
Dynamic backlight Off
Dynamic ContrastOff
Colour EnhancementOff
Picture Format Unscaled
Light SensorOff
Brightness50
Colour0
Contrast100
•Go to the SAM and select “Alignments”-> “White point”.
White point alignment LCD screens:
•Use a 100% white screen as input signal and set the
following values:
– “Colour temperature”: “Normal”.
– All “White point” values to: “127”.
– “Red BL offset” values to “8”.
– “Green BL offset” values to “8”.
In case you have a colour analyser:
•Measure with a calibrated contactless colour analyser in
the centre of the screen. Consequently, the measurement
needs to be done in a dark environment.
•Adjust the correct x,y coordinates (while holding one of the
White point registers R, G or B on 127) by means of
decreasing the value of one or two other white points to the
correct x,y coordinates (see Table 6-1 White D alignment
values). Tolerance: dx: ± 0.004, dy: ± 0.004.
•Repeat this step for the other colour temperatures that
need to be aligned.
•When finished press OK on the RC and then press STORE
(in the SAM root menu) to store the aligned values to the
NVM.
•Restore the initial picture settings after the alignments.

If you do not have a colour analyser, you can use the default
values. This is the next best solution. The default values are
average values coming from production.
•Select a COLOUR TEMPERATURE (e.g. COOL,
NORMAL, or WARM).

6.4Option Settings
6.4.1 Introduction
The microprocessor communicates with a large number of I2C
ICs in the set. To ensure good communication and to make
digital diagnosis possible, the microprocessor has to know
which ICs to address. The presence / absence of these
PNX5100 ICs (back-end advanced video picture improvement
IC which offers motion estimation and compensation features
(commercially called HDNM) plus integrated Ambilight control)
is made known by the option codes.
Notes:
•After changing the option(s), save them by pressing the OK
button on the RC before the cursor is moved to the left,
select STORE in the SAM root menu and press OK on the
RC.
•The new option setting is only active after the TV is
switched “off” / “stand-by” and “on” again with the mains
switch (the NVM is then read again).
6.4.2Dealer Options
offset
The first line (group 1) indicates hardware options 1 to 4, the
second line (group 2) indicate software options 5 to 8.
Every 5-digit number represents 16 bits (so the maximum value
will be 65536 if all options are set).
When all the correct options are set, the sum of the decimal
values of each Option Byte (OB) will give the option number.
See Table 6-3 Option and display code overview
options.
Diversity
Not all sets with the same Commercial Type Number (CTN)
necessarily have the same option code!
Use of Alternative BOM => an alternative BOM number usually
indicates the use of an alternative display or power supply. This
results in another display code thus in another Option code. For
the power supply there is no difference. Refer to Chapter 2.
Important: after having edited the option numbers as
described above, you must press OK on the remote control
before the cursor is moved to the left!
6.5Reset of Repaired SSB
A very important issue towards a repaired SSB from a service
repair shop implies the reset of the NVM on the SSB.
A repaired SSB in service should get the service Set type
“00PF0000000000” and Production code “00000000000000”.
Also the virgin bit is to be set. To set all this, you can use the
ComPair tool.
In case of a display replacement, reset the “Operation hours
display” to “0”, or to the operation hours of the replacement
display.
for the
code
For dealer options, in SAM select “Dealer options”.
See Table 6-4 SAM mode overview
.
6.4.3 (Service) Options
Select the sub menu's to set the initialisation codes (options) of
the model number via text menus.
See Table 6-4 SAM mode overview
.
6.4.4 Opt. No. (Option numbers)
Select this sub menu to set all options at once (expressed in
two long strings of numbers).
An option number (or “option byte”) represents a number of
different options. When you change these numbers directly,
you can set all options very quickly. All options are controlled
via eight option numbers.
When the NVM is replaced, all options will require resetting. To
be certain that the factory settings are reproduced exactly, you
must set both option number lines. You can find the correct
option numbers on a sticker inside the TV set and in Table 6-3
Option and display code overview.
Example: The options sticker gives the following option
numbers:
•08192 00133 01387 45160
•12232 04256 00164 00000
New here in this chassis is the “Net TV” functionality. Therefore
the CTN (“set type” item in CSM1) must be filled into the spare
SSB to ensure access to the Net TV portals.
The loading of the CTN can be done via ComPair (Model
number programming).
The reset item (Clear NET TV memory) can be selected via
MENU (or HOME) => Setup => Installation => Clear NET TV
memory (customer preferences stored at provider side will be
reset now).

6.5.1SSB identification
Whenever ordering a new SSB, it should be noted that the
correct ordering number (12nc) of a SSB is located on a sticker
on the SSB. The format is <12nc SSB><serial number>. The
ordering number of a “Service” SSB is the same as the ordering
number of an initial “factory” SSB.
Figure 6-1 SSB identification
6.6Service SSB delivered without main software
loaded
Due to a changed manufacturing process, new Service SSB’s
can be delivered to the warehouse without main TV
software loaded. Below you find the steps to follow when such
an SSB is received.
6.6.1When a picture is available
1. Mount the Service SSB into the TV set. After start-up,
normally the download application will appear on the
screen.
2. Download the latest main software (FUS) from the
www.p4c.philips.com
website.
3. Create a folder "upgrades" in the root of a USB stick (size
> 50 MB) and save the "autorun.upg" file in this "upgrades"
folder. Note: it is possible to rename this file, e.g.
"Q549_SW_version.upg", this in case there are more than
one "autorun.upg" files on your USB stick
4. Plug the prepared USB stick into the TV set, and select the
"autorun" file in the displayed browser on the screen
5. Now the main TV software will be loaded automatically,
supported by a progress bar
6. Set the correct "display code" via "062598-HOME-xxx",
where "xxx" is the 3-digit display panel code (see sticker on
the side/bottom of the cabinet).
6.6.2When no picture is available
Due to a possible wrong display option code in the received
Service SSB (NVM), no picture can be available at start-up and
thus no download application will be visible. Here you can
proceed and finalize step by step to load the main TV software
via the UART logging on the PC (for visual feedback).
1. Start-up the TV set, equipped with the Service SSB, and
enable the UART logging on the PC (see for settings 5.8
Fault Finding and Repair Tips5.8.6 Logging)
2. The TV set will start-up automatically in the download
application if main TV software is not loaded
3. Plug the prepared USB stick into the TV set, press cursor
"Right" to enter the list, and navigate to the "autorun" file in
the UART logging printout via the cursor keys on the
remote control. When the correct file is selected, press
"OK"
4. Press cursor "Down" and "OK" to start the flashing of the
main TV software. Printouts like: "L: 1-100% , V: 1-100%
and P: 1-100%" should be visible now in the UART logging
5. Wait until the message "Operation successful!” is
displayed and remove all inserted media. Restart the TV
set
6. Set the correct "display code" via "062598-HOME-xxx",
where "xxx" is the 3-digit display panel code (see sticker on
the side/bottom of the cabinet).
6.6.3Use of repaired SSBs instead of new
Repaired SSBs on stock will obviously already contain main TV
software. This implies that only a main software upgrade is
required if you use a “repaired” SSB for board swap instead of
a “new” SSB.

Circuit Descriptions
7.2.1Power Supply Unit
All power supplies are a black box for Service. When defective,
a new board must be ordered and the defective one must be
returned, unless the main fuse of the board is broken. Always
replace a defective fuse with one with the correct
specifications! This part is available in the regular market.
Consult the Service website for the order codes of the boards.
Figure 7-3 Power Architecture TV543/92 platform
In the TV543 Elite Core platform, for sets up to and including
47", the Integrated Power Board (IPB) - incl. inverter is used.
For sets of 52 " and 56", a conventional PSU (with additional
inverters) is used.
In this manual, no detailed information is available because of
design protection issues.
The output voltages to the chassis are:
•+3V3-STANDBY (standby-mode only)
•+12V (on-mode)
•+Vsnd (+24V) (audio power) (on-mode)
•+24V (bolt-on power) (on-mode)

Circuit Descriptions
Figure 7-6 EDID control (embedded EDID)
EN 45Q549.2E LA7.
Figure 7-4 Front-End block diagram
The DRX3926K is a multi-standard demodulator supporting
DVB-C, DVB-T and analogue standards. The demodulated
digital stream is fed into the parallel transport stream data ports
of the PNX8543. The demodulated analogue signal in the form
of CVBS is connected to the analogue video CVBS/Y input
channel, while the SIF is connected via the SSIF2 positive input
port.
7.4HDMI
In this platform, the TDA9996 HDMI multiplexer is
implemented. Only for one HDMI input, a separate EEPROM is
implemented to store the EDID values. For the other HDMI
inputs, the EDID contents are no longer stored in a separate
EEPROM, but directly in the multiplexer. Each input has its own
physical subaddress: the first 253 bytes are common, where
the last 3 bytes define the specific input. The EDID contents
are, at +5V power-up, downloaded to RAM. The following
figures show the HDMI input configuration and EDID control.
The delta’s with respect to the use of the TDA9996 as HDMI
multiplexer compared with earlier chassis/platforms are:
•+5V detection mechanism
•Stable clock detection mechanism
•Integrated EDID
•RT control
•HPD control
•TMDS output control
•CEC control
•New hotplug control for PNX8543 for 5th HDMI input
•New EDID structure: EDID stored in TDA9996, therefore
there are no EDID pins on the SSB. Only in the event of a
5th HDMI input, an additional EEPROM is foreseen, as
was implemented in previous platforms.
After replacement of the TDA9996 HDMI mux, the default I
address should be reprogrammed from C0 to CE, and the
HDMI EDIDs should be reprogrammed as well. Both actions
should be executed via ComPair.
7.5Video and Audio Processing - PNX8543
The PNX8543 is the main audio and video processor (or
System-on-Chip) for this platform. It is a member of the
PNX85xx SoC family (described in earlier chassis) with the
addition of the MPEG4 functionality; the separate STi710x
MPEG4 decoder is no longer implemented in this platform.

Figure 7-5 HDMI input configuration
Some more delta’s compared to the previous PNX85xx are:
•2 HDMI inputs (A & B)
•HDMI deep colour RGB/YCbCr 4:4:1 10/12 bit detection.
The PNX8543 handles the digital and analogue audio- and
video decoding and processing. The processor is a MIPS32
general purpose CPU and a 8051-based TV controller for
power management and user event handling.
•For a functional diagram of the PNX8543, refer

7.6Common Interface CI+
Together with this platform, an extention to the Common
Interface (CI) Conditional Access system is added, called CI+.
CI+ or Common Interface Plus is a specification that extends
the Common Interface (DVB-CI) as described in the digital
broadcasting standard DVB.
The weakness of the conventional CI module as Conditional
Access system was the absence of a Copy Protection
mechanism, as decrypted content could be sent over the
PCMCIA interface unscrambled. With the CI+ extension, a
form of copy protection is established between the Conditional
Access Module (CAM) and the Integrated Digital Television
(IDTV). The security mechanisms in CI+ are derived/copied
from POD (with the exception of Out Of Band (OOB) used in
US CA systems). For more information about conventional CA
systems using a CI module, refer to the BJ3.0E L/PA or BL2.xU
Service Manual.
The CI+ standard is downwards compatible with the existing CI
standard.
The following figure shows the implementation of the CI+
Conditional Access system in the TV543 platform.

7.8.1ARM controller
Refer to Figure 7-13
below for signal interfacing to and from the
ARM controller. The ARM controller is located on the DC/DC
board (item no. 7302) or AL panel (item no. 7102).
Figure 7-13 ARM controller interface
Data transfer between ARM processor and LED drivers is
executed by a Serial Peripheral Interface (SPI) bus interface.
The SPI bus is a synchronous serial data link standard that
operates in full duplex mode.
For debugging purposes, the working principle is given below:
•At startup the controller will read-out matrix data from the
EEPROM devices (via SPI DATA RETURN)
•Before operation, the driver current is set via SPI, with
driver in DC mode
•During normal operation the controller receives RGB-,
configuration-, operation mode- and topology data via I
•The controller converts the I
2
C RGB data via the matrixes
to SPI LED data
•Via data return the controller receives error data (if
applicable).
Also PWM clock and BLANK signals are generated by the
controller. The controller can be reprogrammed via I
USB). The controller can receive matrix values via I
will be stored in the EEPROM of each AL module via the SPI
bus. The temperature sensor in each AL module controls the
TEMP line; in case of a too high temperature the controller will
reduce the overall brightness.
7.8.2LED driver communication (via SPI bus)
Refer to Figure 7-14
below for signal interfacing between the
ARM controller and the LED drivers on the AL boards, and the

Figure 7-14 SPI communication between ARM controller and LED drivers
The ARM controller communicates with the LED drivers (on
each AL module) via an SPI bus. For debugging purposes, the
working principle is given below:
•Data from the ARM controller is linked through the drivers,
which are connected in cascade
•SPI CLK, SPI LATCH, PROG, BLANK and PWM CLOCK
are going directly from the controller to each driver
•SPI DATA RETURN is linked from the last driver to the
controller: controller decides which driver returns data.
7.8.3Temperature Control
Circuit Descriptions
Refer to Figure 7-15
for signal interfacing between the ARM
controller and the temperature sensor on the AL boards.
Figure 7-15 Communication between ARM controller and
temperature sensor
Each AL board is equipped with a temperature sensor. If one of
the sensors detects a temperature over the threshold, the
TEMP line is pulled LOW which results in brightness reduction.
