Index of this chapter:
Safety Instructions
3.1
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.
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
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 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.
3.3.3Spare Parts
For the latest spare part overview, consult your Philips Spare
Part web portal.
3.3.4BGA (Ball Grid Array) ICs
Introduction
For more information on how to handle BGA devices, visit this
URL: http://www.atyourservice-magazine.com
“Magazine”, then go to “Repair downloads”. Here you will find
Information on how to deal with BGA-ICs.
BGA Temperature Profiles
For BGA-ICs, you must use the correct temperature-profile.
Where applicable and available, this profile is added to the IC
Data Sheet information section in this manual.
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”.
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

Precautions, Notes, and Abbreviation List
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.
SN is Lysomice, RJ is Kobierzyce), 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 2010 week 10 / 2010
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.

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: 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.
– 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 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
ComPair”).
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).
5.2.1 Service Default Mode (SDM)
Purpose
•To create a pre-defined setting, to get the same
measurement results as given in this manual.
•To override software 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

After activating this mode, “SDM” will appear in the upper right
corner of the screen (when a picture is available).
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.
•To view operation hours.
•To display (or clear) the error code buffer.
•All picture settings at 50% (brightness, colour, contrast).
•Sound volume at 25%.
•All service-unfriendly modes (if present) are disabled, like:
– (Sleep) timer.
– Child/parental lock.
– Picture mute (blue mute or black mute).

– 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 software 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, see chapter 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 “062598” directly followed by the “MENU” (or "HOME")
button and “XXX” (where XXX is the 3 digit decimal display
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.

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.

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 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,
•Software/Hardware 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
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

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 (diagram B02A) 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.

5.4Service 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
2. ComPair allows very detailed diagnostics and is therefore
3. ComPair speeds up the repair time since it can
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 can be
blown!
How to Order
ComPair II order codes:
•ComPair II interface: 3122 785 91020.
•Software is available via the Philips Service web portal.

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

Service Modes, Error Codes, and Fault Finding
•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.
•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.
•Via polling on I/O pins going to the stand-by processor.
•Via sensing of analog values on the stand-by processor or
the PNX8550.
•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, 5.8.6
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

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...).

follows: SCL-UP-M IP S, SDA-UP-MIPS.
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 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 28 (Channel dec DVB-S). When there is no I2C
communication towards the DVB-S channel decoder,
LAYER 2 error = 28 will be logged and displayed via the
blinking LED procedure if SDM is switched on.
•Error 31 (Lnb controller). When there is no I
communication towards this device, LAYER 2 error = 31
will be logged and displayed via the blinking LED
procedure if SDM is activated.
•Error 34 (Tuner). When there is no I

C communication
towards the tuner during start-up, LAYER 2 error = 34 will
be logged and displayed via the blinking LED procedure
when SDM is switched on.
•Error 35 (main NVM). When there is no I
communication towards the main NVM during start-up,
LAYER 2 error = 35 will be displayed via the blinking LED
procedure when SDM is switched “on”. All service modes
(CSM, SAM and SDM) are accessible during this failure,
observed in the Uart logging as follows: "<< ERRO >>>
PFPOW_.C: First Error (id19, Layer_1= 2 Layer_= 35)".
•Error 36 (Tuner DVB-S). When there is no I
communication towards the DVB-S tuner during start-up,
LAYER 2 error = 36 will be logged and displayed via the
blinking LED procedure when SDM is switched “on”.
•Error 37 (Class-D amplifier). When there is no I
communication towards the TAS5731PHP Class-D
Amplifier during start-up, LAYER 2 error = 37 will be logged
and displayed via the blinking LED procedure when SDM
is switched “on”.
Note: TV in normal working condition, but without Audio out
from speaker.
•Error 42 (Temp sensor). Only applicable for TV sets
equipped with temperature devices.
•Error 53. This error will indicate that the PNX8550 has
read his bootscript (when this would have failed, error 15
would blink) but initialization was never completed because
of hardware problems (NAND flash, ...) or software
initialization problems. Possible cause could be that there
is no valid software loaded (try to upgrade to the latest main
software version). Note that it can take a few minutes
before the TV starts blinking LAYER 1 error = 2 or in SDM,
LAYER 2 error = 53.
5.6The Blinking LED Procedure
5.6.1 Introduction
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.
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,
Error code overview”) and will be

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
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, 5.8.6 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.
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 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
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 audio amplifier (item
7D60; see diagram B06A) 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.
5.8Fault Finding and Repair Tips
Read also section “5.5 Error Codes, 5.5.4 Error Buffer, Extra
Info”.
5.8.1Audio Amplifier
The Class D-IC 7D60 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.
5.8.2 AV 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).
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...)
5.8.4DC/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 PNX855xx, 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 PNX855xx.
•+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
PNX855xx device, for various other internal blocks of
PNX855xx; 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 PNX855xx. Stabilizer
7UC0 is used (diagram B02B).
•+3V3 supply voltage (3V3 nominal), is provided by 7UD1
(diagram B02C); the 12 V to 3V3 DC-DC converter delivers
the supply voltage to the PNX855xx.
•+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 PNX855xx.
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 7TP2 (diagram B03B) 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 7TP2.
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 con
inside 7TP2 are activated. Initially only the 24V to 5V converter
(channel 1 of 7TP2 generating +5V-DVBS) will effectively work,
while +V-LNB is held at a level around 11V7 via diode 6TP5.
If +24V drops below +15V level then the DVB-S2 supply will
stop, even if +3V3 is still present.
Note: +24V audio is used in 4000 series, 4300 & 5000 series
use +12V audio.
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
•Behaviour 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) 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,
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.

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

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:

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.
5.8.7Guidelines Uart logging
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 PNX855xx 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 erros, 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.
•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).
• I
•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 software 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!
5.8.9PSL
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).
5.8.10 Tuner
Attention: In case the tuner is replaced, always check the tuner
options!
5.8.11 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.
While in the download application (start up in TV mode + “OK”
button pressed), the display option code can be changed via
062598 HOME XXX special SAM command (XXX=display
option in 3 digits).

Step #Action to doAdvise / Attention points / Remarks
1Ensure ESD protection by using a wristband2If SSB is still functional: Go via SAM to “upload to USB” and copy Personal
settings - Option codes - Alignments (Presets) - Set Identification.
Advice: because of differences in memory a llocatio n, it is a dvised to upg rade
main SW before copying data from existing SSB. Copy of Preset list is
possible from normal user interface.
3Disconnect set from mains and from antenna.Safety and ESD!
4Open the set and disconnect LVDS flat cable. Disconnect other cables /
connections.
5Dismount the (defective) SSB from the set.Do not damage SSB copper tracks with your tools! Do not scratch bottom of SSB (be very careful
6Place new SSB in the set, and fixate/mount carefully.Do not damage SSB copper tracks with your tools! Do not scratch bottom of SSB (be very careful
7Connect PSU and other connectors. Insert the optional WiFi module.Make sure that the connectors are correctly plugged-in and locked (click). Special at tention for the
8Connect LVDS connector(s).Be very careful: wrong or bad connection can damage the TCON part on the SSB and damage
9Connect set to mains and switch TV “On”. Check start-up of the set, backlight switch “On”…
10If the set does not start (or reboots) check:
- The connectors from the power supply,
- The power supply cable and connection pins,
- LVDS cable connection.
11Before programming the new SSB, upgrade to late st software. If set is starting
up in software upgrade mode, then first install new software via software
Upgrade Menu or via the autorun.upg file.
12If set is starting up without picture or menu (OSD), first program the correct
Display Option codes.
13Go to SAM and program “Set type” and “Serial number”. This is possible via
the NVM editor and virtual keyboard. In case personal settings were
recovered from the defective SSB, you can use an “Upload from USB”.
14Check if option codes are correct, and keys are present. SSBs with integrated
TCON needs TCON alignment in SAM. A djust White point co lour temperature
alignment for normal, warm and cool according to values in section 6.3.1
15Update to latest software (Standby and main software). This step is ne cessary
to make sure that the (optional) 200 Hz T-CON board has the latest software.
Display drive, and White point colour temperature needs to be aligned! See
section 6.3.1
16Once the set is playing, check cable connection between PSU and SSB, by
moving the cable if there are no bad connections.
17Fill in the Electronic DDF (Defect Description Form): Fault symptom, TV type
and TV serial number.
18Install presets or check if all presets are OK. Check in CSM if Type number,
Serial number, Main and Standby software are correct.
19Check connectivity to Net TV and DLNA. Check AmbiLight functionality.Only for sets having these functionalities.
20Inform customer about Memory Card, USB, or Hard drive PVR (Personal
Video Recording) recordings.

Table 5-3 SSB replacement instructions
Upload to USB: A directory “repair” will be created on the USB, and all data will be copied in this
directory. On sets with software before Q552-xx-140-x-x, there was an issue by copying the
program map table, so it is advised to reinstall the programs from Virgin mode instead of using
copy via USB.
Always take care for ESD! Be extra careful when removing connectors!

case do a trial without WiFi module.
the LCD display. Check if flat cables are fitted correctly before closing the connector lock.
Power supply connector must “snap” into the socket.
Some SSB’s will start-up in software upgrad e mode, and software needs to b e installed before you
can program the Display Optio n codes. It’s adviced to use an autorun.upg file for software
upgrade, this in case you have no OSD on the screen.
Use blind service mode “062598” + “Home” button, directly followed by the
Display Option code (3 digits). Set will switch to Standby after Display Option code is entered.
Programming “Set type” and “Serial number ” i s ma nda to ry to ha ve al l fun c tionality of the set, like
DLNA, Net TV… For certain sets you may need to use ComPair for this.
Attention, check if Tuner on defect board and new b oard is the same. If not, the same Tun er option
code nbr 1 needs to be adapted (add or substract 512). refer to Gen eral Service Info GSC_893 08.
.
Validity of HDCP, CI+, Marlin, and WDRM keys can be checked via ComPair.
Even when the SSB already has the latest softwar e, it is mand atory to upgra de again the software
to update the 200 Hz T-CON part. At the end of the main software update process, a dedicated
software is loaded, from the main processor via the LVDS connection, to upgrade the
200 Hz T-CON part. For certain LCD displays, a dedicated Display software patch (autoscript) is
available. See General Service info GSC_85590.
Check the two power connectors 1M95 and 1M99. Bad contact or bad connection here can give
reboots.
It is mandatory to fill in the E-DDF form (see the “At Your Service” web portal).
Special attention for Standby software: check if Standby software ID is matching wi th the D-RAM’s
mounted on the SSB (2 × Elpida = 73, 4 × Elpida = 64, 2 × Hynix = 72, 4 × Hynix = 63).
Inform customer that previous recordings ma de on Memory Card (movi e download), USB, or Hard
drive will be lost. USB or Hard drive needs to be re-formatted and matched with new SSB (WDRM
Keys!).

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

Spare Parts list!
5.9.2 Main Software Upgrade
•The “UpgradeAll.upg” file is only used in the factory.
Figure 5-14 SSB start-up
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.
back to
div. table
2012-Jun-29
EN 38Q552.4E 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
remote control while reconnecting the TV to the Mains/AC
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.

– “Colour temperature”: “Cool”.
– All “White point” values to: “127”.
In case you have a colour analyser:
•Measure, in a dark environment, with a calibrated
contactless colour analyser (Minolta CA-210 or Minolta
CS-200) in the centre of the screen and note the x, y value.
•Change the pattern to 90% white screen. If a Quantum
Data generator is used, select the “GreyAll” test pattern at
level = 230.
•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
values - LED - Minolta CA-210, or 6-2 White D alignment

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
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).

From 2011 onwards, it is not longer possible to change
individual option settings in SAM. Options can only be changed
all at once by using the option codes as described in section
6.4.4
.
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:
•32776 00001 15421 02235
•43847 36615 33024 00012
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.
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 Specs, Diversity, 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”).
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.
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, 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).
After a SSB repair, the original channel map can be restored,
provided that the original channel map was stored on a USB
stick before repair was commenced and that basic functionality
of the TV, needed for this procedure, was not hampered as a
result of the defect. The procedure of “channel map cloning” is
clearly described in the (electronic) user manual.
In case of a display replacement, reset the “Operation hours
display” to “0”, or to the operation hours of the replacement
display.
