3.1 Safety 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.
3.2 Warnings
3.3.2 Schematic Notes
• All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 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
-6
),
nano-farads (n 10
-9
), or pico-farads (p 10
-12
).
• Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
• An “asterisk” (*) indicates component usage varies. Refer
to the diversity tables for the correct values.
• The correct component values are listed on the Philips
Spare Parts Web Portal.

Introduction
For more information on how to handle BGA devices, visit this
URL: http://www.atyourservice-magazine.com
. Select
“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.
3.3.5 Lead-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

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.

4.2 Service 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.

5.1 Test 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.
5.2 Service 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.
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 SW protections detected by the standby
processor and make the TV start up to the step just before
• Digital SDM: use the 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.
Figure 5-1 Service mode pad
After activating this mode, “SDM” will appear in the upper right
corner of the screen (when a picture is available).
How to Exit SDM
Use one of the following methods:
• Switch the set to STANDBY via the RC-transmitter.
• Via a standard customer RC-transmitter: key in “00”sequence.
5.2.2 Service Alignment Mode (SAM)

be re-written to NVM. The update can be done via the
NVM editor available in SAM.
• Operation hours. Displays the accumulated total of
operation hours (not the standby hours). Every time the TV
is switched “on/off”, 0.5 hours is added to this number.
• Errors (followed by maximum 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see section “5.5
Error Codes”).
• Reset Error Buffer. When “cursor right” (or “OK” button)
pressed here, followed by the “OK” button, the error buffer
is reset.
• Alignments. This will activate the “ALIGNMENTS” submenu. See Chapter 6.
Alignments.
• Options numbers. Extra features for Service. For more
info regarding option codes, see chapter 6.
Alignments.
Note that if the option code numbers are changed, these
have to be confirmed with pressing the “OK” button before
the options are stored, otherwise changes will be lost.
• Initialise NVM. The moment the processor recognizes a
corrupted NVM, the “initialise 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).
– Initialise the NVM.
Note: When the NVM is corrupted, or replaced, there is a high
possibility that no picture appears because the display code is
not correct. So, before initializing the NVM via the SAM, a
picture is necessary and therefore the correct display option
has to be entered. Refer to Chapter 6.
Alignments for details.
To adapt this option, it’s advised to use ComPair (the correct
values for the options can be found in Chapter 6.
Alignments)
or a method via a standard RC (described below).
Changing the display option via a standard RC: Key in the
code “062598” directly followed by the “MENU” (or "HOME")
button and “XXX” (where XXX is the 3 digit decimal display
code as mentioned 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
• Test settings. For development purposes only.
• RF4CE pairing tables. Clear paired remote control. Repairing (coldboot of platform possibly needed) can be done
by pressing the red/blue hot keys simultaneously for a few
seconds.(be sure the distance between the remote control
and TV set RF4CE receiver is less then 30cm). Message
like “Pairing successful”, confirms the match-make.
• Development 1 file versions. Not useful for Service
purposes, this information is mainly used by the
development department.
• Development 2 file versions. Not useful for Service
purposes, this information is mainly 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
“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 the upload of all several items at once.
A directory “repair\” will 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.
Important remark : to upload the “channel list”, select
“Home” => “Setup” => “TV settings” => “General settings”
=> “Channel list copy” => “Copy to USB”.The procedure is
also described in the (electronic) user manual.
• 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”. The “All” item
supports to download all several items at once.
Important remark : to download the “channel list”, select
“Home” => “Setup” => “TV settings” => “General settings”
=> “Channel list copy” => “Copy to TV”. The procedure is

EN 22 QFU1.2E LA5.
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.
Provided CSM is activated, every menu from CSM can be used
as check for the back end chain video.So for all CSM content
displayed, it could be determined that the back end video chain
is working.
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.xml) will be
saved in the root of the USB stick. This info can be handy if no
information is displayed.
Additional in CSM mode (with USB stick connected), pressing
“OK” will create an extended CSM dump file on the USB stick.
This file (Extended_CSM_model number_serial number.xml)
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.
Attention: for every dump which imply data tranfers to USB,
• Production code. Displays the production code (the serial
number) of the TV. Note that if an NVM is replaced or is
initialized after corruption, the production code content has
to be re-written to NVM. The update can 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 by time extraction.
• Options 1. Displays the option codes numbers of option
group 1 as set in SAM (Service Alignment Mode).
• Options 2. Displays the option codes numbers 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. The update can be done via the NVM editor available
in SAM. This identification number is the 12nc number of
the SSB.
• 12NC display. Shows the 12NC of the display. Note that if
an NVM is replaced or is initialized after corruption, this
identification number has to be re-written to NVM. The
update can be done via the NVM editor available in SAM.
• 12NC supply. Shows the 12NC of the power supply. Note
that if an NVM is replaced or is initialized after corruption,
this identification number has to be re-written to NVM. The
update can be done via the NVM editor available in SAM.
• 12NC sensor board. Shows the 12NC of the sensor
board.
Software versions
• Current main software. Displays the build-in main
software version. In case of field problems related to
software, upgrade can be done. As this software is
consumer upgradeable, it will also be published on the
Internet.
Example: QF2xx-1.2.3.4
• Standby software. Displays the build-in standby
processor software version. Upgrading this software will be
possible via USB (see section 5.9
Software Upgrading).
Example: STDBY_77.3.11.16
• e-UM version. Displays the electronic user manual SWversion (12NC version number). Most significant number

The ComPair Tool is no longer supported.
5.5 Error Codes
5.5.1 Introduction
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.
• 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(s) LAYER 1 will be
displayed via blinking LED.(attention: any new remote
• On screen via the SAM (only when a picture is visible).
E.g.:
– 00 00 00 00 00: No errors detected
– 23 00 00 00 00: Error code 23 is the last and only
detected error.
– 37 23 00 00 00: Error code 23 was first detected and
error code 37 is the last detected error.
– Note that no protection errors can be logged in the
error buffer.
• Via the blinking LED procedure. See section 5.5.3
How to
Clear the Error Buffer.
•Via ComPair.
5.5.3 How to Clear the Error Buffer
Use one of the following methods:
• By activation of the “RESET ERROR BUFFER” command
in the SAM menu.
• 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 standby processor.
• Via sensing of analog values on the standby processor or
the Mips.
• Via a “not acknowledge” of an I
2
C communication.
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.

EN 30 QFU1.2E LA5.
Table 5-2 Error code overview
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.
• Error 13 (I
2
C bus M3, SSB + SRF bus blocked). Current
situation: when this error occurs, the TV can reboot due to
the blocked bus. The best way for further diagnosis here, is
to check the logging output.
• Error 14 (I
2
C bus M2, BE bus blocked). Current situation:
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
2
C
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
2
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
2
C
communication towards the main NVM during start-up,
LAYER 2 error = 35 will be displayed via the blinking LED
