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.
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 M and 12 M.
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.
•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 k).
•Resistor values with no multiplier may be indicated with
either an “E” or an “R” (e.g. 220E or 220R indicates 220 ).
•All capacitor values are given in micro-farads (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.

. Select

),
).
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
3.3.1General
•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
picture carrier at 475.25 MHz for PAL, or 61.25 MHz for
NTSC (channel 3).
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.
3.3.6Alternative BOM identification
It should be noted that on the European Service website,
“Alternative BOM” is referred to as “Design variant”.

Precautions, Notes, and Abbreviation List
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.

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!
3.3.8Practical 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.

4.3Service Positions
For easy servicing of a TV set, the set should be put face down
on a soft flat surface, foam buffers or other specific workshop
tools. Ensure that a stable situation is created to perform
measurements and alignments. When using foam bars take
care that these always support the cabinet and never only the
display. Caution: Failure to follow these guidelines can
seriously damage the display!
Ensure that ESD safe measures are taken.

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: Color 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.
•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-favorite pre-sets.
How to Activate SDM
For this chassis there are two kinds of SDM: an analogue SDM
and a digital SDM. Tuning will happen according Table 5-1
•AnalogueSDM: 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.
AnalogueSDM can also be activated by grounding for a
moment the solder path on the SSB, with the indication
“SDM” (see Service mode pad
•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.
).
.
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
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
•To start the blinking LED procedure where only LAYER 2
errors are displayed. (see also section “5.5

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.
How to Activate SAM
Via a standard RC transmitter: Key in the code “062596”
directly followed by the “INFO” or “OK” 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 6-11
•Hardware Info.
– A. SW Version. Displays the software version of the
main software (example: Q555X-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
•Reset Error Buffer. When “cursor right” (or “OK” button)
pressed here, followed by the “OK” button, the error buffer
is reset.
•Alignments. This will activate the “ALIGNMENTS” submenu. See Chapter 6.
•Dealer Options. Extra features for the dealers.
•Options. Extra features for Service. For more info
regarding option codes, 6.
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.
To adapt this option, it’s advised to use ComPair (the correct
values for the options can be found in Chapter 6.
or a method via a standard RC (described below).
Changing the display option via a standard RC: Key in the

code as mentioned on the sticker in the set). Make sure to key
in all three 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 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.

•Store - go right. All options and alignments are stored
when pressing “cursor right” (or the “OK” button) and then
the “OK”-button.
•Operation hours display. Displays the accumulated total
of operation hours of the screen itself. In case of a display
replacement, reset to “0” or to the consumed operation
hours of the spare display.
•SW Maintenance.
– SW Events. In case of specific software problems, the
development department can ask for this info.
– HW Events. In case of specific software problems, the
development department can ask for this info :
- Event 26: refers to a power dip, this is logged after
the TV set reboots due to a power dip.
- Event 17: refers to the power OK status, sensed even
before the 3 x retry to generate the error code.
•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”,
“Alignments”, “Identification data” (includes the set type
and prod code + all 12NC like SSB, display, boards),
“History list”. The “All” item supports to upload all several
items at once.
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 the message “Done” appears. In case the
download to the USB stick was not successful, “Failure” will
be displayed. 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 into another TV
or other SSB. Uploading is of course only possible if the
software is running and preferably 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 from USB. To download several settings from
the USB stick to the TV, same way of working needs to be
followed as described in “Upload to USB”. 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. The “All” item supports
to download all several items at once.

•NVM editor. For NET TV the set “type number” must be
entered correctly.
Also the production code (AG code) can be entered here
via the RC-transmitter.
Correct data can be found on the side/rear sticker.
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.
•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.
5.2.3Customer 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 test pattern 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 PNX51X0
(located on the 200Hz board as part of the display). So if this
test pattern is shown, it could be determined that the back end
video chain (PNX51X0 and display) is working.For TV sets
without the PNX51X0 inside, every menu from CSM will be
used as check for the back end chain video.
When CSM is activated and there is a USB stick connected to
the TV set, the software will dump the CSM content to the USB
stick. The file (CSM_model number_serial number.txt) will be
saved in the root of the USB stick. This info can be handy if no
information is displayed.
When in CSM mode (and a USB stick connected), pressing
“OK” will create an extended CSM dump file on the USB stick.
This file (Extended_CSM_model number_serial number.txt)
contains:
•The normal CSM dump information,
•All items (from SAM “load to USB”, but in readable format),
•Operating hours,
•Error codes,
•SW/HW event logs.
To have fast feedback from the field, a flashdump can be
requested by development. When in CSM, push the “red”
button and key in serial digits ‘2679’ (same keys to form the
word ‘COPY’ with a cellphone). A file “Dump_model
number_serial number.bin” will be written on the connected
USB device. This can take 1/2 minute, depending on the
quantity of data that needs to be dumped.
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
2010-Dec-29
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.
Contents of CSM
The contents are reduced to 3 pages: General, Software
versions and Quality items. The group names itself are not
shown anywhere in the CSM menu.
General
•Set Type. This information is very helpful for a helpdesk/
workshop as reference for further diagnosis. In this way, it
is not necessary for the customer to look at the rear of the
TV-set. Note that if an NVM is replaced or is initialized after
corruption, this set type has to be re-written to NVM.
ComPair will foresee in a possibility to do this. The update
can also be done via the NVM editor available in SAM.
•Production Code. Displays the production code (the serial
number) of the TV. 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. The update can also be done via the NVM editor
available in SAM.
•Installed date. Indicates the date of the first installation of
the TV. This date is acquired via time extraction.
•Options 1. Gives the option codes of option group 1 as set
in SAM (Service Alignment Mode).
•Options 2. Gives the option codes of option group 2 as set
in SAM (Service Alignment Mode).
•12NC SSB. Gives an identification of the SSB as stored in
NVM. Note that if an NVM is replaced or is initialized after
corruption, this identification number has to be re-written to
NVM. ComPair will foresee in a possibility to do this. This
identification number is the 12nc number of the SSB.
•12NC display. Shows the 12NC of the display.
•12NC supply. Shows the 12NC of the power supply.
•12NC 200Hz board. Shows the 12NC of the 200Hz Panel
(when present).
•12NC AV PIP. Shows the 12NC of the AV PIP board (when
present).
Software versions
•Current main SW. Displays the build-in main software
version. In case of field problems related to software,
software can be upgraded. As this software is consumer
upgradeable, it will also be published on the Internet.
Example: Q55xx1.2.3.4
•Stand-by SW. Displays the build-in stand-by processor
software version. Upgrading this software will be possible
via ComPair or via USB (see section 5.9
Software
Upgrading).
Example: STDBY_88.68.1.2.
•e-UM version. Displays the electronic user manual SWversion (12NC version number). Most significant number
here is the last digit.
•AV PIP software.
•3D dongle software version.
Quality items
•Signal quality. Bad / average /good (not for DVB-S).
•Ethernet MAC address. Displays the MAC address
present in the SSB.
•Wireless MAC address. Displays the wireless MAC
address to support the Wi-Fi functionality.
•BDS key. Indicates if the set is in the BDS status.
•CI module. Displays status if the common interface
module is detected.
•CI + protected service. Yes/No.

How to Exit CSM
Press “MENU” (or "HOME") / “Back” key on the RC-transmitter.
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 SDM solder path 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. Caution: in case the start-up
in this mode with a faulty FET 7U0X is done, you can destroy
all IC’s supplied by the +1V8 and +1v1, due to overvoltage (12V
on XVX-line). It is recommended to measure first the FET
7U0X 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.

5.4.1ComPair
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 µP
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.
Figure 5-10 ComPair II interface connection
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 can be
blown!
How to Order

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:
•If no errors are there, the LED should not blink at all in
CSM or SDM. No spacer must be displayed as well.
•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.
•In CSM mode.
– When entering CSM: error LAYER 1 will be displayed
•In SDM mode.
– When SDM is entered via Remote Control code or the
•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
•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 Buffer”. 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.
5.5.2How 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
– 37 23 00 00 00: Error code 23 was first detected and
– Note that no protection errors can be logged in the

•Via the blinking LED procedure. See section 5.5.3 How to
Clear the Error Buffer.
•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.
•If the content of the error buffer has not changed for 50+
hours, it resets automatically.
5.5.4Error 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.
•Via polling on I/O pins going to the stand-by processor.
•Via sensing of analog values on the stand-by processor or
the PNX85500.
•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.

Extra Info
•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, 5.8.7
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, SSB bus blocked). 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 14 (I
2
C bus 2, TV set bus blocked). 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 18 (I
2
C bus 4, Tuner bus blocked). In case this bus
is blocked, short the “SDM” solder paths on the SSB during
startup, LAYER error 2 = 18 will be blinked.
•Error 15 (PNX8550 doesn’t boot). Indicates that the main
processor was not able to read his bootscript. This error will
point to a hardware problem around the PNX8550
(supplies not OK, PNX 8550 completely dead, I
between PNX and Stand-by Processor broken, etc...).
When error 15 occurs it is also possible that I
blocked (NVM). I

Other root causes for this error can be due to hardware
problems regarding the DDR’s and the bootscript reading
from the PNX8550.
•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 21 (PNX51X0). When there is no I
2
C communication
towards the PNX51X0 after start-up, LAYER 2 error = 21
will be logged and displayed via the blinking LED
procedure if SDM is switched on. This device is located on
the 200 Hz panel from the display.
•Error 23 (HDMI). When there is no I
2
C communication
towards the HDMI mux after start-up, LAYER 2 error = 23
will be logged and displayed via the blinking LED
procedure if SDM is switched on.
•Error 24 (I2C switch). When there is no I

C switch, LAYER 2

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
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
displayed when SDM (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 an empty error buffer, the LED should not blink at all in
CSM or SDM. No spacer will be displayed.

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 (spacer).
6. The sequence starts again.
5.6.2How to Activate
Use one of the following methods:
•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 Stand-by 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, 5.8.7 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.
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:
•Related to supplies: presence of the +5V, +3V3 and 1V2
needs to be measured, no protection triggered here.
•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 optimize 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
5.7.2Hardware Protections
Stepwise Start-up”).
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 (spacer).
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

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 audio amplifier (item
7D10; see diagram B03A) and puts the amplifier in a
continuous burst mode (cyclus approximately 2 seconds).
Repair Tip
•There still will be a picture available but no sound. While
the Class D amplifier tries to start-up again, the cone of the
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. The headphone amplifier will
also behaves similar.

Read also section “5.5 Error Codes, 5.5.4 Error Buffer, Extra
Info”.
5.8.1Ambilight
Due to degeneration process of the LED’s fitted on the ambi
module, there can be a difference in the color and/or light
output of the spare ambilight modules in comparison with the
originals ones contained in the TV set. Via SAM => alignments
=> ambilight, the spare module 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.
5.8.3AV PIP
To check the AV PIP board (if present) functionality, a
dedicated tespattern can be invoke as follows: select the
“multiview” icon in the User Interface and press the “OK”
button. Apply for the main picture an extended source, e.g.
HDMI input. Proceed by entering CSM (push ‘123654’ on the
remote control) and press the yellow button. A coloured
testpattern should appear now, generated by the AV PIP board
(this can take a few seconds).
•+5V-TUN supply voltage (5V nominal) for tuner and IF
amplifier.
+3V3-STANDY (3V3 nominal) is the permanent voltage,
supplying the Stand-by microprocessor inside PNX85500.
Supply voltage +1V1 is started immediately when +12V voltage
becomes available (+12V is enabled by STANDBY signal when
"low"). Supply voltages +3V3, +2V5, +1V8, +1V2 and +5V-TUN
are switched "on" by signal ENABLE-3V3 when "low", provided
that +12V (detected via 7U40 and 7U41) is present.
+12V is considered OK (=> DETECT2 signal becomes "high",
+12V to +1V8, +12V to +3V3, +12V to +5V DC-DC converter
can be started up) if it rises above 10V and doesn’t drop below
9V5. A small delay of a few milliseconds is introduced between
the start-up of 12V to +1V8 DC-DC converter and the two other
DC-DC converters via 7U48 and associated components.
Description DVB-S2:
•LNB-RF1 (0V = disabled, 14V or 18V in normal operation)
LNB supply generated via the second conversion channel
of 7T03 followed by 7T50 LNB supply control IC. It provides
supply voltage that feeds the outdoor satellite reception
equipment.
•+3V3-DVBS (3V3 nominal), +2V5-DVBS (2V5 nominal)
and +1V-DVBS (1.03V nominal) power supply for the
silicon tuner and channel decoder. +1V-DVBS is generated
via a 5V to 1V DC-DC converter and is stabilized at the
point of load (channel decoder) by means of feedback
signal SENSE+1V0-DVBS. +3V3-DVBS and +2V5-DVBS
are generated via linear stabilizers from +5V-DVBS that by
itself is generated via the first conversion channel of 7T03.
5.8.4CSM
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...)
5.8.5DC/DC Converter
Description basic board
The basic board power supply consists of 4 DC/DC converters
and 5 linear stabilizers. All DC/DC converters have +12V input
voltage and deliver:
•+1V1 supply voltage (1.15V nominal), for the core voltage
of PNX85500, stabilized close to the point of load;
SENSE+1V1 signal provides the DC-DC converter the
needed feedback to achieve this.
•+1V8 supply voltage, for the DDR2 memories and DDR2
interface of PNX85500.
•+3V3 supply voltage (3.30V nominal), overall 3.3 V for
onboard IC’s, for non-5000 series SSB diversities only.
•+5V (5.15V nominal) for USB, WIFI and Conditional
Access Module and +5V5-TUN for +5V-TUN tuner
stabilizer.
The linear stabilizers are providing:
•+1V2 supply voltage (1.2V nominal), stabilized close to
PNX85500 device, for various other internal blocks of
PNX85500; SENSE+1V2 signal provides the needed
feedback to achieve this.
•+2V5 supply voltage (2.5V nominal) for LVDS interface and
various other internal blocks of PNX85500; for 5000 series
SSB diversities the stabilizer is 7UD2 while for the other
diversities 7UC0 is used.
•+3V3 supply voltage (3V3 nominal) for 5000 series SSB
diversities, provided by 7UD3; in this case the 12V to 3V3
DC-DC converter is not present.
At start-up, +24V becomes available when STANDBY signal is
"low" (together with +12V for the basic board), when +3V3 from
the basic board is present the two DC-DC converters channels
inside 7T03 are activated. Initially only the 24V to 5V converter
(channel 1 of 7T03 generating +5V-DVBS) will effectively work,
while +V-LNB is held at a level around 11V7 via diode 6T55.
After 7T05 is initialized, the second channel of 7T03 will start
and generates a voltage higher then LNB-RF1 with 0V8. +5VDVBS start-up will imply +3V3-DVBS start-up, with a small
delay of a few milliseconds => +2V5-DVBS and +1V-DVBS will
be enabled.
If +24V drops below +15V level then the DVB-S2 supply will
stop, even if +3V3 is still present.
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 stand-by 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 +1V1 is started immediately.
After ENABLE-3V3 goes "low", all the other supply voltages
should rise within a few milliseconds.
Tips
•Behavior comparison with a reference TV550 platform can
be a fast way to locate failures.
•If +12V stays "low", check the integrity of fuse 1U40.
•Check the integrity (at least no short circuit between drain
and source) of the power MOS-FETs before starting up the
platform in SDM, otherwise many components might be
damaged. Using a ohmmeter can detect short circuits
between any power rail and ground or between +12V and
any other power rail.
•Short circuit at the output of an integrated linear stabilizer
(7UC0, 7UD2 or 7UD3) will heat up this device strongly.
•Switching frequencies should be 500 kHz ...600 kHz for
12 V to 1.1 V and 12 V to 1.8 V DC-DC converters,

Service Modes, Error Codes, and Fault Finding
900 kHz for 12 V to 3.3 V and 12 V to 5 V DC-DC
converters. The DVB-S2 supply 24 V to 5 V and 24 V to +V
LNB DC-DC converters operates at 300 kHz while for 5 V
to 1.1 V DC-DC converter 900 kHz is used.
5.8.6Exit “Factory Mode”
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.
5.8.7Logging
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 “Q55X.X”, 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.
•Failure messages should be checked and investigated.For
instance fatal error on the PNX51x0: check startup of the
back-end processor, supplies..reset, I
2
C bus. => error
mentioned in the logging as: *51x0 failed to start by itself*.
•Some failures are indicated by error codes in the logging,
check with error codes table (see Table “5-2
overview”).e.g. => <<<ERROR>>>PLFPOW_MERR.C :
First Error (id=10,Layer_1=2,Layer_2=23).
2
• I
C bus error mentioned as e.g.: “ I2C bus 4 blocked”.
•Not all failures or error messages should be interpreted as
fault.For instance root cause can be due to wrong option
codes settings => e.g. “DVBS2Suppoprted : False/True.
In the UART log startup script we can observe and check the
enabled loaded option codes.
Defective sectors (bad blocks) in the Nand Flash can also be
reported in the logging.
Startup in the SW upgrade application and observe the UART
logging:
Starting up the TV set in the Manual Software Upgrade mode
will show access to USB, meant to copy software content from
USB to the DRAM.Progress is shown in the logging as follows:
“cosupgstdcmds_mcmdwritepart: Programming 102400 bytes,
40505344 of 40607744 bytes programmed”.
Startup in Jett Mode:
Check UART logging in Jet mode mentioned as : “JETT UART
READY”.
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!
5.8.10 PSL
In case of no picture when CSM (test pattern) is activated and
backlight doesn’t light up, it’s recommended first to check the
inverter on the PSL + wiring (LAYER 2 error = 17 is displayed
in SDM).
Error code
Description possible cases:
UART loggings are displayed:
•When UART loggings are coming out, the first conclusion
we can make is that the TV set is starting up and
communication with the flash RAM seems to be supported.
The PNX85500 is able to read and write in the DRAMs.
•We can not yet conclude : Flash RAM and DRAMs are fully
operational/reliable.There still can be errors in the data
transfers, DRAM errors, read/write speed and timing
control.
No UART logging at all:
•In case there is no UART logging coming out, check if the
startup script can be send over the I
2
C bus (3 trials to
startup) + power supplies are switched on and stable.
•No startup will end up in a blinking LED status : error
LAYER 1 = “2”, error LAYER 2 = “53” (startup with SDM
solder paths short).
•Error LAYER 2 = “15” (hardware cause) is more related to
a supply issue while error LAYER 2 = “53” (software cause)
refers more to boot issues.

5.8.11 Tuner
Attention: In case the tuner is replaced, always check the tuner
options!
5.8.12 Display option code
Attention: In case the SSB is replaced, always check the
display option code in SAM, even when picture is available.
Performance with the incorrect display option code can lead to
unwanted side-effects for certain conditions.

The set software and security keys are stored in a NANDFlash, which is connected to the PNX85500.
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 electronic User Manual.
Important: When the NAND-Flash must be replaced, a new
SSB must be ordered, due to the presence of the security keys!
(CI +, 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 CI + key, MAC address.. are valid.
For the correct order number of a new SSB, always refer to the
Spare Parts list!
5.9.2Main Software Upgrade
•The “UpgradeAll.upg” file is only used in the factory.
Figure 5-13 SSB start-up
back to
div. table
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
_Q555X_ x.x.x.x_prod.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 operational. 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.
2010-Dec-29
Page 40
EN 40Q552.1L LA5.
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 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 “CURSOR DOWN”-button on a Philips TV

Power.
3. The back-up 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.
StandbyFactory_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.

•Go to the SAM and select “Alignments”-> “White point”.
White point alignment LCD screens:
•Use a 90% white screen to the HDMI input and set the
following values:
– “Color temperature”: “Normal”.
– All “White point” values to: “127”.
In case you have a color analyzer:
•Measure, in a dark environment, with a calibrated
contactless color analyzer (Minolta CA-210 or Minolta CS-
200) in the centre of the screen.
•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

Sets with forward integration have the TCON on SSB. The
alignment of this TCON is stored in the SSB, and is related to
the used display. When an SSB or a display is replaced, a new
value must be entered.
A default value (see table below) is copied from the display file
(after entering the correct display code) and is shown in the
SAM menu. But on top of this, the default value can be
overruled manually via the menu item “TCON alignment”.
The current value is shown with 4 digits, and can be changed
by a digit entry. After pressing “OK”, the value is stored.
The menu item "Reset TCON alignment" can be used to return
to the default value from the display file. A notification is shown:

the wiring path, starting at the small signal panel,
proceeding towards the ambient light modules.The first
module will be attached to the next module 2. Module
number 2 to number 3 etc..as follows the way to define the
ambilight module numbering.
5. Align the brightness compared with the neighboring
modules. The brightness is automatically stored.
6. Select one of 10 matrixes which color matches most with
the neighboring modules, “matrix 0” is the factory
alignment and can always be retrieved. (see table “6-7

6.4Option Settings
6.4.1Introduction
The microprocessor communicates with a large number of I
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
PNX51XX 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
•The new option setting is only active after the TV is

See Table 6-11 SAM mode overview.
6.4.3(Service) Options
Select the sub menu's to set the initialization codes (options) of
the model number via text menus.
See Table 6-11
SAM mode overview.
6.4.4Opt. 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.
Example: The options sticker gives the following option
numbers:
•08192 00133 01387 45160
•12232 04256 00164 00000
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.
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
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.
Refer to Chapter 2.
Technical Specifications, and Connections.
6.4.5Option Code Overview
Refer to the sticker in the set for the correct option codes.
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 (SSB repair on component level) 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 or use the “NVM editor” and “Dealer options”
items in SAM (do not forget to “store”).
After a repaired SSB has been mounted in the set (set repair
on board level), the type number (CTN) and production code of
the TV has to be set according to the type plate of the set. For
this (new in this platform), you can use the NVM editor in
SAM. This action also ensures the correct functioning of the
“Net TV” feature and access to the Net TV portals. The loading
of the CTN and production code can also be done via ComPair
(Model number programming).
In case of a display replacement, reset the “Operation hours
display” to “0”, or to the operation hours of the replacement
display.

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 Philips Service web portal for the order codes of the
boards.
Important delta’s with the TV543 platform are:
•New power architecture for LED backlight (PSL, PSLS,
PSDL)
•“Boost”-signal is now a PWM-signal + continuous variable.
The control signals are:
•Standby
•Lamp “on/off”
•DIM (PWM) (not for PSDL)
•Boost (PWM except for IPB)
•Power-OK: indicates that the main converter is functioning
(feedback signal to the SSB).
In this manual, no detailed information is available because of
design protection issues.
•Output to the display; in case of
- IPB: High voltage to the LCD panel
- PSL and PSLS (LED-driver outputs)
- PSDL (high frequent) AC-current.
7.2.2Diversity
The diversity in power supply units is mainly determined by the
diversity in displays.
The following displays can be distinguished:
•CCFL/EEFL backlight: power board is conventional IPB
•LED backlight:
- side-view LED without scanning: PSL power board
- side-view LED with scanning: PSLS power board
- direct-view LED without 2D-dimming: PSL power board
- direct-view LED with 2D-dimming: PSDL power board.
•PSL stands for Power Supply with integrated LED-drivers.
•PSLS stands for a Power Supply with integrated LEDdrivers with added Scanning functionality (added
microcontroller).
•PSDL stands for a Power Supply for Direct-view LED
backlight with 2D-dimming.
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)

7.5HDMI
In this platform, the Silicon Image Sil9x87 HDMI multiplexer is
implemented. Refer to figure 7-8
the application.
New in this platform is the implementation of the Audio Return
Channel (ARC) (pin 14 on HDMI 1). The ARC in HDMI1.4
enables a TV, via a single HDMI cable, to send audio data
“upstream” to an A/V receiver or surround audio controller,
increasing user flexibility and eliminating the need for any
separate SPDIF audio connection.
HDMI input configuration for
•Embedded HDMI HDCP keys
•Extended color gamut and color booster
•Integrated USB2.0 host controller
•Improved MPEG artefact reduction compared with
PNX8543
•Security for customers own code/settings (secure flash).
The TV550 combines front-end video processing functions,
such as DVB-T channel decoding, MPEG-2/H.264 decode,
analogue video decode and HDMI reception, with advanced
back-end video picture improvements. It also includes next
generation Motion Accurate Picture Processing (MAPP2). The
MAPP2 technology provides state-of-the-art motion artifact
reduction with movie judder cancellation, motion sharpness
and vivid color management. High flat panel screen resolutions
and refresh rates are supported with formats including 1366 ×
768 @ 100Hz/120Hz and 1920 × 1080 @ 100Hz/120Hz. The
combination of Ethernet, CI+ and H.264 supports new TV
experiences with IPTV and VOD. On top of that, optional
support is available for 2D dimming in combination with LED
backlights for optimum contrast and power savings up to 50%.
For a functional diagram of the PNX85500, refer
to Figure 7-9
.
Figure 7-8 HDMI input configuration
The following multiplexers can be used:
•Sil9187A (does not support “Instaport” technology for fast
switching between input signals)
•Sil9287B (supports “Instaport” technology for fast
switching between input signals).

Notes to figure 7-21 TCON block diagram:
•LVDS receiver: converts the data stream back into RGB
data and SYNC signals (Vsync, Hsync, Data Enable - DE)
•ODC: Over Drive Circuit - to improve LC response
•Data Path Block: the video RGB data input to data path
block is delayed to align the column driver start pulse with
the column driver data
•Timing Control Function: generates control signals to
column drivers and row drivers (Source Enable - SOE,
Gate Enable - GOE, Gate Start Pulse - GSP).
For an overview of the TCON DC/DC converters, refer to figure
7-22
TCON DC/DC converters.
7.9.1TCON Programming
For LGD - TCONs, the EEPROM can be programmed via
ComPair (via I
For Sharp - TCONs, the data can be flashed with a “SPI
Programmer” (via SPI communication). This device has to be
ordered separately via Philips.
7.9.2TCON Alignment
The purpose of TCON alignment is to obtain equal voltages for
both positive and negative LC polarity. This is to avoid “flicker”
and “image sticking”. For alignment, see 6.3.3
