Precautions, Notes, and Abbreviation List

Index of this chapter:
3.1 Safety Instructions
3.2 Warnings
3.3 Notes
3.4 Abbreviation List
3.1Safety Instructions
Safety regulations require the following during a repair:
•Connect the set to the Mains/AC Power via an isolation
transformer (> 800 VA).
•Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
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
3.3.1General
•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).
•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!
3.3.8Practical 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.

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.
4.3.1Rear Cover
Warning: Disconnect the mains power cord before removing
the rear cover.
Attention: All sets are equipped with a hatch to disconnect the
keyboard control panel. Ambilight sets are in addition equipped
with a hatch to disconnect the Ambilight units.
These hatches are indicated on the rear cover with
SERVICE h.
It is mandatory to open the hatches and disconnect the
cables prior to removal of the rear cover!
See Figure 4-18
1. For sets equipped with Ambilight: open the hatch that
covers the Ambilight connector and unplug the connector

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.
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 the
solder path on the SSB, with the indication “SDM” (see
figures Service mode pad - front
back.
•DigitalSDM: 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.
) and Service mode pad -
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).
5.2.1Service 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 the standby
processor and make the TV start up to the step just before
protection. See section “5.3 Start-up
”.
•To start the blinking LED procedure where only LAYER 2
errors are displayed. (see also section “5.5 Error Codes

Contents of SAM
•Hardware Info.
– A. SW Version. Displays the software version of the
main software (example: QF1XX-1.2.3.4 =
AAABB_X.Y.W.Z).
•AAA= the chassis name.
•BB= Product ID.
•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
Figure 5-3 Location of Display Option Code sticker
compatible with a lower number).
– B. Standby processor version. Displays the software
version of the standby 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. 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.
•Store - go right. All options and alignments are stored
when pressing “cursor right” or the “OK” button.
•Software 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.
•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
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 (Standby) as an indication
that the RC sequence was correct. After the display option is
changed in the NVM, the TV will go to the Standby 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.
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

here via the RC-transmitter.Be sure the cursor is put fully
to the left (use back key) of the dialog box before enter the
new data.
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.
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.txt) 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.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.(see also section 5.5 Error Codes
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.
2012-Sep-14
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, the set type content has to be re-written to
NVM.The update can 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, 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 RF4CE board. Shows the 12NC of the RF4CE
board.
Software versions
•Current main software. 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.

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
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.

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.
•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 Standby software which lead to protection. These errors will always lead to protection and
an automatic start of the blinking LED LAYER 1 error.
(see section “5.6 The Blinking LED Procedure
•Errors detected by the Standby software which not lead to protection. In this case the front LED should blink
the involved error. See also section “5.5 Error Codes
Error Buffer”. 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

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

Service Modes, Error Codes, and Fault Finding
•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 standby processor.
•Via sensing of analog values on the standby processor or
the Mips.
•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.

•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,

•Error 15 (Fusion 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 Fusion (supplies
not OK, Fusion device completely dead, link between Mips
and Stand-by Processor broken, etc...)
Other root causes for this error can be due to hardware
problems regarding the DDR’s and the bootscript reading
from the Fusion device.

•Error 38 (FPGA ScanBacklight). When there is no I
communication towards this FPGA device during start-up,
LAYER 2 error = 38 will be logged and displayed via the
blinking LED procedure when SDM is switched “on”. This
device supports the backlight + boost pwm control,
scanning, 3D drive and ambilight buffering.
•Error 42 (Temp sensor). Only applicable for TV sets
equipped/stuffed with temperature devices.

communication towards the light sensor device during
start-up, LAYER 2 error = 43 will be logged and displayed
via the blinking LED procedure when SDM is switched “on”.
•Error 44 (Touch control). When there is no I
communication towards the touch control micro processor
during start-up, LAYER 2 error = 44 will be logged and
displayed via the blinking LED procedure when SDM is
switched “on”.

C communication
towards the RF4CE driver during start-up, LAYER 2
error = 46 will be logged and displayed via the blinking LED
procedure when SDM is switched “on”.
•Error 53. This error will indicate that the Fusion device has
read his bootscript (when this would have failed, error 15
would blink) but initialization was never completed because
of hardware problems (NAND flash, DDR...) 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
(maintain grounding continuously), LAYER 2 error = 53.
5.6The Blinking LED Procedure
5.6.1Introduction
The blinking LED procedure can be split up into two situations:
•Blinking LED procedure LAYER 1 error. In this case the
error is automatically blinked when the TV is put in CSM.
This will be only one digit error, namely the one that is
referring to the defective board (see table “5-2 Error code
overview”) which causes the failure of the TV. This
approach will especially be used for home repair and call
centres. The aim here is to have service diagnosis from a
distance.
•Blinking LED procedure LAYER 2 error. Via this
procedure, the contents of the error buffer can be made
visible via the front LED. In this case the error contains
2 digits (see table “5-2 Error code overview
displayed when SDM (hardware pins) is activated. This is
especially useful for fault finding and gives more details
regarding the root cause of the defective board.

”) and will be
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,
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
2
C
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 the
layer 1 error(s), this works in “normal operation” mode or
automatically when the error/protection is monitored by the
Standby processor.
In case no picture is shown and there is no LED blinking,
read the logging to detect whether “error devices” are
mentioned. (see section “5.8 Fault Finding and Repair
Tips, 5.8.6 Logging”).
•Activate the SDM. The blinking front LED will show the
entire content of the LAYER 2 error buffer, this works in
“normal operation” mode or when SDM (via hardware pins)
is activated when the tv set is in protection.
5.7Protections
5.7.1Software Protections
Most of the protections and errors use either the standby
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

Info”.
5.8.1Ambilight
Due to the aging process on the LED’s fitted on the Ambilight
module, there can be a difference in the colour 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 fine-tuned.
Other possibility: the original values can also be recovered via
SAM, Upload to USB => alignments. Now the original settings
are on the USB stick and can be reloaded into another SSB
(NVM).
5.8.2CSM
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...)
5.8.3DC/DC Converter
Description
Input power for the TV platform comes from the main power
supply that delivers +3V3STANDBY (pin 1 of connector 1M95)
and +12V (pins 5,6 of the same connector). +3V3STANDBY
(3.3V nominal) is the permanent voltage, supplying the standby
microprocessor inside the Fusion chip while +12V is started by
the STANDBY signal (connector 1M95, pin 2) when going from
high to low. +12V is split in three branches via fuses 1UA0
(+12Va), 1UA1 (+12Vb) and 1UP1(+12-DVBS):
•+12Va serves as input voltage for the switching voltage
regulators that deliver +1V1-FD and +1V5.
•+12Vb is used as input voltage for the switching voltage
regulators that deliver +3V3 and +5V.
•+12V-DVBS (if DVB-S functionality is present) goes to 12V
to +1V0-DVBS and 12V to +V-LNB switching regulators.
The on board power supply consists of 4 switching voltage
regulators (6 in case of DVB-S version), 6 linear voltage
regulators (7 in case of DVB-S version) one power switch
delivering +3V3AL for Ambilight driver boards and an overcurrent protection for 12V (AMBI-POWER) Ambilight boards.
All switching voltage regulators have 12V input voltage and
deliver:
•+1V0-DVBS core supply voltage for DVB-S2 demodulator
(1.02V nominal), stabilized close to the point of load by
means of SENSE+1V0-DVBS signal.
•+1V1-FD Fusion main core supply voltage (0.95V...1.2V depending on DVS1 signal), stabilized close to the point of
load by means of SENSE+1V1-FD signal.
•+1V5 supply voltage (1.53V nominal), for the DDR3
memories and DDR3 interface of the Fusion chip.
•+3V3 supply voltage (3.37V nominal): overall 3.3V for on
board IC’s and for WiFi module, also used as input voltage
for linear voltage regulators delivering +1V1-FA, +1V2-FA
and +2V5.
•+5V (5.15V nominal) for USB, WiFi, Conditional Access
Module and via linear voltage regulators, the DVB-T and
DVB-S tuner supplies.
•+V-LNB (13V or 18V) supply for outdoor satellite reception
equipment.
The linear voltage regulators are providing:
”).
•+1V1-FA supply voltage (1.10V nominal, from +3V3) for
low power analog (PLL) blocks inside Fusion chip.
•+1V2-MIPS supply voltage (1.05...1.3V depending on
DVS2 signal, input voltage: +1V5) for Fusion auxiliary core.
•+1V2-FE supply voltage (1.20V nominal, from +1V5) for
HDMI multiplexer and (if present) DVB-T2 demodulator IC
device.
•+1V2-FA supply voltage (1.20V nominal, from +3V3) for
higher power analog Fusion internal blocks (mainly video
ADC’s).
•+2V5 supply voltage (2.5V nominal, from +3V3) for LVDS
(or Vby1) interface and various other internal blocks of
Fusion.
•+3V3 supply voltages (3.3V nominal, from +5V) for RF
tuners, separate linear regulator per tuner.
Supply voltages +1V1-FD, +1V5 and +1V2-MIPS are started
immediately when +12V rises above the 5V level. The rest of
the supply voltages (+5V, +3V3, +2V5, +1V2-FA and +1V1-FA
are turned on by signal DETECT12V when becomes high. The
tuners are supplied from their respective linear voltage
regulators when +5V starts.+1V0-DVBS is started almost at the
same time, when +2V5-DVBS (derived from +3V3-DVBS via
the equivalent diode 7RC2) rises.
DETECT12V becomes high when +12V rises above 10V and
stays above 9.5V (0.5V hysteresis).
+3V3AL will become available when e
(signal ENABLE-3V3-AMBI high).In case of TV sets having
Ambilight consumption from 12V + higher than 1A, the
electronic protection circuit (7UAC and surrounding
components) is used instead of fuse 1UA2. AMBI-POWER
should be available shortly (100 ms) after +12V starts if there
is no load on it. The over-current trigger level is around 4.1A.
Once triggered, it can be reset by removing the shortcircuit
cause and keeping it under no load condition for about 100 ms.
+V-LNB value is determined via software: around 13V for
vertical polarized satellite channels and around 18V for the
horizontal ones. Maximum current is limited in both cases to
400mA
Debugging
The best way to find a failure in the DC/DC converters is to
check their start-up sequence at power “on”, presuming that
the external supply is operational. Take the STANDBY signal
"high"-to-"low" transition as trigger reference and check the
power start-up sequence as described above.
Tips
•Behaviour comparison with a working Fusion platform can
be a fast way to locate failures.
•Check first the integrity of fuses 1UA0, 1UA1 and (if
present) 1UA2 and 1UP1.
•If a fuse is found interrupted: check the respective +12Va
(or +12Vb or +12V-DVBS) short circuit with all of the
derived supply voltages, for example: a +12Va ->+1V5
short circuit will probably be caused by a defective 7UB5
integrated circuit.
•Switching frequency should be around 400KHz for 12V to
+V-LNB switching voltage regulator, 500KHz for +12V to
+1V1-FD and 600KHz...700KHz for the others.
•When a short circuit to GND is found on one of the supply
voltage delivered by a switching voltage regulator, then try
first removing the power coil(s) from the output filter of the
converter, this to point the location of the short circuit (at
converter side or at load side).

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 to exit the
“Factory mode”.
5.8.6Logging
When something is wrong with the TV set (f.i. the set is
rebooting) you can check for more information via the logging
in Hyperterminal. The Hyperterminal is available in every
Windows application via Programs, Accessories,
Communications, Hyperterminal. Connect a “ComPair UART”cable (3138 188 75051) from the service connector in the TV to
the “multi function” jack at the front of ComPair II box.
Required settings in ComPair before starting to log:
- Start up the ComPair application.
- Select the correct database (open file “QFU1X.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 “display number xxx” 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 Fusion processor 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:
•No startup will end up in a blinking LED status: error
LAYER 1 = “2”, error LAYER 2 = “53” (startup with SDM
solder paths continuous 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.
•Some failures are indicated by error codes in the logging,
check with error codes table (see Table “5-2 Error code
overview”). e.g. => <<<ERROR>>>PLFPOW_MERR.C :
First Error (id=10,Layer_1=2,Layer_2=23).
2
C bus errors.
•I
•Not all failures or error messages should be interpreted as
fault. For instance root cause can be due to wrong option

In the Uart log startup script we can observe and check the

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 feedback can be found in the
logging.
Startup in Jett Mode:
Check Uart logging in Jet mode mentioned as : “JETT UART

5.8.8Loudspeakers
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!
5.8.9Power Supply
In case of no picture when CSM (test pattern) is activated and
backlight doesn’t light up, it’s recommended first to check the
LED drivers on the PSL(S) + wiring (LAYER 2 error = 17 is
displayed in SDM).
5.8.10 Display option code
Attention: In case the SSB is replaced, always check the
display option code number (group 2, first option number e.g.
“44855”) in SAM, even when picture is available. Performance
with the incorrect display option code can lead to unwanted
side-effects for certain conditions.
Also supported in this chassis:
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).

7Connect PSU and other connectors. Insert the optional WiFi module.Make sure that the connectors are correctly plugged-in and locked (click). Special attention 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 switching “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 programmi ng the new SSB, upgrade to latest softwa re. 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, a nd keys are present. S SBs with integra ted
TCON needs TCON alignment in SAM.
15Update to latest software (Standb y and main software). This step is necessary
to make sure that the (optional) 200Hz T-CON board has the latest software.
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.
For a more general overview of steps to follow, refer to figure
5-13 SSB replacement flowchart
.
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.
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!).

5.9.1Introduction
The set software and security keys are stored in a NANDFlash, which is connected to the Fusion processor.
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 numbers (see rearcover sticker).
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 Set type, MAC address are valid.
For the correct order number of a new SSB, always refer to the
Spare Parts list!
).
Figure 5-15 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. QF1EU_0.88.0.0.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 (attention : not supported
by use of RF4CE remote due to the fact this application is
not running yet at the time of the “OK” request). Keep the
“OK” button pressed while reconnecting the TV to the
Mains/AC Power.
3. The software upgrade application will start.
5.9.2Main Software Upgrade
•The “UpgradeAll.upg” file is only used in the factory.

Attention!
In case the download application has been started manually,
the “autorun.upg” will maybe not be recognized.
2012-Sep-14
EN 38QFU1.1E LA5.
What to do in this case:
1. Create a directory “UPGRADES” on the USB stick.
2. Rename the “autorun.upg” to something else, e.g. to
“software.upg”. Do not use long or complicated names,
keep it simple. Make sure that “AUTORUN.UPG” is no
longer present in the root of the USB stick.
3. Copy the renamed “upg” file into this directory.
4. Insert USB stick into the TV.
5. The renamed “upg” file will be visible and selectable in the
upgrade application.
Back-up Software Upgrade Application
If the default software upgrade application does not start (could
be due to a corrupted boot 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.(attention : not supported by use of RF4CE remote
due to the fact this application is not running yet at the time
of the “CURSOR-DOWN” request).
3. The back-up software upgrade application will start.
5.9.3Standby Software Upgrade via USB
Service Modes, Error Codes, and Fault Finding
In this chassis it is possible to upgrade the Standby software
via a USB stick. The method is similar as upgrading the main
software via USB.
Use the following steps:
1. Create a directory “UPGRADES” on the USB stick.
2. Copy the Standby software (one-zip file StandbyUpgrade,
e.g. StandbyFactory_61.0.0.00_13.00.00.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.

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.
Notes:
•After changing the option number(s), save them by
pressing the “OK” button on the RC before the cursor is
moved to the left, select “STORE” in the SAM root menu
and press “OK” on the RC.
•The new option setting is only active after the TV is
switched “off” / “stand-by” and “on” again with the mains
switch (the NVM is then read again).
6.4.2(Service) Options
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
.
6.4.3
6.4.3Opt. 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 the rearcover sticker from the TV set.
Example: The options sticker gives the following option
numbers:
•Group 1 : 08192 00133 01387 45160

•Group 2 : 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.
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.
6.4.4Option Code Overview
Refer to the rearcover 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 needs to be set. To set all this, you can use
the ComPair tool or use the “NVM editor” and “Setup => TV
settings => General settings => Reinstall TV” (virgin mode).
access to the Smart 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.
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 the correct “Service” SSB is the one
preceded by the letter “S” in case 2 or more ordering numbers
are present on the bar code sticker.
After a repaired SSB has been mounted in the set (set repair
on board level), the type number (CTN) and production code +
12NC’s (SSB, display and supply) of the TV has to be set
according the type plate of the set (no info on 12NC’s here). For
this, you can use the NVM editor in SAM. This action also
ensures the correct functioning of the “Smart TV” feature and

7.2.1Power Supply Unit
All power supplies are a black box for Service. When any of
these power supplies is 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.
