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 MΩ and 12 MΩ.
4. Switch “off” the set, and remove the wire between the
two pins of the Mains/AC Power plug.
•Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
•Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.
3.3.2Schematic Notes
•All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kΩ).
•Resistor values with no multiplier may be indicated with
either an “E” or an “R” (e.g. 220E or 220R indicates 220 Ω).
•All capacitor values are given in micro-farads (μ=× 10
nano-farads (n =× 10
•Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
•An “asterisk” (*) indicates component usage varies. Refer
to the diversity tables for the correct values.
•The correct component values are listed on the Philips
Spare Parts Web Portal.

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.

. Select

),
).
3.2Warnings
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this same potential.
•Be careful during measurements in the high voltage
section.
•Never replace modules or other components while the unit
is switched “on”.
•When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.
3.3Notes
3.3.1 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).
3.3.5Lead-free Soldering
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin. If lead-free solder paste is
required, please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
•Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able:
– To reach a solder-tip temperature of at least 400°C.
– To stabilize the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.
•Adjust your solder tool so that a temperature of around
360°C - 380°C is reached and stabilized at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
•Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
3.3.6Alternative BOM identification
It should be noted that on the European Service website,
“Alternative BOM” is referred to as “Design variant”.

Precautions, Notes, and Abbreviation List
The third digit in the serial number (example:
AG2B0335000001) indicates the number of the alternative
B.O.M. (Bill Of Materials) that has been used for producing the
specific TV set. In general, it is possible that the same TV
model on the market is produced with e.g. two different types
of displays, coming from two different suppliers. This will then
result in sets which have the same CTN (Commercial Type
Number; e.g. 28PW9515/12) but which have a different B.O.M.
number.
By looking at the third digit of the serial number, one can
identify which B.O.M. is used for the TV set he is working with.
If the third digit of the serial number contains the number “1”
(example: AG1B033500001), then the TV set has been
manufactured according to B.O.M. number 1. If the third digit is
a “2” (example: AG2B0335000001), then the set has been
produced according to B.O.M. no. 2. This is important for
ordering the correct spare parts!
For the third digit, the numbers 1...9 and the characters A...Z
can be used, so in total: 9 plus 26= 35 different B.O.M.s can be
indicated by the third digit of the serial number.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 1 and 2 refer to the production centre (e.g.
AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers
to the Service version change code, digits 5 and 6 refer to the
production year, and digits 7 and 8 refer to production week (in
example below it is 2006 week 17). The 6 last digits contain the
serial number.

3.3.7 Board 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.

5.1 Test Points
5.2 Service Modes
5.3 Service Tools
5.4 Error Codes
5.5 The Blinking LED Procedure
5.6 Fault Finding and Repair Tips
5.7 Software Upgrading
5.1Test Points
In the chassis schematics and layout overviews, the test points
are mentioned. In the schematics, test points are indicated with
“Fxxx” or “Ixxx”, in the layout overviews with a “half-moon” sign.
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. Several key ICs are
capable of generating test patterns, which can be controlled via
ComPair. In this way it is possible to determine which part is
defective.
Perform measurements under the following conditions:
•Service Default Mode.
•Video: Color bar signal.
•Audio: 3 kHz left, 1 kHz right.
5.2Service Modes
The Service Mode feature is split into four parts:
•Service Default Mode (SDM).
•Service Alignment Mode (SAM).
•Customer Service Mode (CSM).
•Computer Aided Repair Mode (ComPair).
SDM and SAM offer features, which can be used by the Service
engineer to repair/align a TV set. Some features are:
•A pre-defined situation to ensure measurements can be
made under uniform conditions (SDM).
•Activates the blinking LED procedure for error identification
when no picture is available (SDM).
•The possibility to overrule software protections when SDM
is entered via the Service pins.
•Make alignments (e.g. White Tone), (de)select options,
enter options codes, reset the error buffer (SAM).
•Display information (“SDM” or “SAM” indication in upper
right corner of screen, error buffer, software version,
operating hours, options and option codes, sub menus).
The CSM is a Service Mode that can be enabled by the
consumer. The CSM displays diagnosis information, which the
customer can forward to the dealer or call centre. In CSM
mode, “CSM”, is displayed in the top right corner of the screen.
The information provided in CSM and the purpose of CSM is to:
•Increase the home repair hit rate.
•Decrease the number of nuisance calls.
•Solved customers' problem without home visit.
ComPair Mode is used for communication between a computer
and a TV on I2C /UART level and can be used by a Service
engineer to quickly diagnose the TV set by reading out error
codes, read and write in NVMs, communicate with ICs and the
uP (PWM, registers, etc.), and by making use of a fault finding
database. It will also be possible to up and download the
software of the TV set via I2C with help of ComPair. To do this,
ComPair has to be connected to the TV set via the ComPair
connector, which will be accessible through the rear of the set
(without removing the rear cover).
5.2.1Service Default Mode (SDM)
Purpose
Set the TV in SDM mode in order to be able to:
•Create a pre-defined setting for measurements to be
made.
•Override software protections.
•Start the blinking LED procedure.
•Read the error buffer.
•Check the life timer.

•Set linear video and audio settings to 50%, but volume to
25%. Stored user settings are not affected.
•All service-unfriendly modes (if present) are disabled, since
they interfere with diagnosing/repairing a set. These
service unfriendly modes are:
– (Sleep) timer.
– Blue mute/Wall paper.
– Auto switch “off” (when there is no “ident” signal).
– Hotel or hospital mode.
– Child lock or parental lock (manual or via V-chip).
– Skipping, blanking of “Not favorite”, “Skipped” or
“Locked” presets/channels.
– Automatic storing of Personal Preset or Last Status
settings.
– Automatic user menu time-out (menu switches back/
OFF automatically.
– Auto Volume levelling (AVL).
How to Activate SDM
For this chassis there are two kinds of SDM: an analog SDM
and a digital SDM. Tuning will happen according Table 5-1
•AnalogSDM: use the standard RC-transmitter and key in
the code “062596”, directly followed by the “MENU” (or
HOME) button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it “off”, push the “MENU” (or
HOME) button again.
•DigitalSDM: use the standard RC-transmitter and key in
the code “062593”, directly followed by the “MENU” (or
HOME) button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it “off”, push the “MENU” (or
HOME) button again.
•AnalogSDM can also be activated by grounding for a
moment the solder pad on the SSB, with the indication
“SDM” (see figure Service mode pad
475.25PAL B/G
).

more info regarding option codes, see chapter .
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.
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.
5.2.2 Service Alignment Mode (SAM)
Purpose
•To perform (software) alignments.
•To change option settings.
•To easily identify the used software version.
•To view operation hours.
•To display (or clear) the error code buffer.
How to Activate SAM
Via a standard RC transmitter: Key in the code “062596”
directly followed by the “INFO” button. After activating SAM
with this method a service warning will appear on the screen,
continue by pressing the “OK” button on the RC.
Contents of SAM (see also Table 6-4

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.
)
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. To adapt this option bit, it is advised to use
ComPair (the correct values for the options can be found in
Table 6-3
) or a method via a standard RC (described below).
Changing the display option via a standard RC: Key in the
code “062598” directly followed by the “MENU” (or HOME)
button and “XXX” (where XXX is the 3 digit decimal display
code as mentioned in Table 6-3
). Make sure to key in all three
digits, also the leading zero’s. If the above action is successful,
the front LED will go out as an indication that the RC sequence
was correct. After the display option is changed in the NVM, the
TV will go to the Stand-by mode. If the NVM was corrupted or
empty before this action, it will be initialized first (loaded with
default values). This initializing can take up to 20 seconds.

•Store - go right. All options and alignments are stored
when pressing “cursor right” (or the “OK” button) and then
the “OK”-button.
•SW Maintenance.
– SW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
– HW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
•Operation hours display. Displays the accumulated total
of display operation hours. So, this one keeps up the
lifetime of the display itself, mainly to compensate the
degeneration behavior.

•Test settings. For development purposes only.
•Development file versions. Not useful for Service
purposes, this information is only used by the development
department.
•Upload to USB. To upload several settings from the TV to
an USB stick, which is connected to the SSB. The items are
“Channel list”, “Personal settings”, “Option codes”,
“Display-related alignments” and “History list”. First a
directory “repair\” has to be created in the root of the
USB stick. To upload the settings select each item
separately, press “cursor right” (or the “OK” button),
confirm with “OK” and wait until “Done” appears. In case
the download to the USB stick was not successful “Failure”
will appear. In this case, check if the USB stick is
connected properly and if the directory “repair” is present in
the root of the USB stick. Now the settings are stored onto
the USB stick and can be used to download onto another
TV or other SSB. Uploading is of course only possible if the
software is running and if a picture is available. This
method is created to be able to save the customer’s TV
settings and to store them into another SSB.
•Download to USB. To download several settings from the
USB stick to the TV, same way of working needs to be
followed as with uploading. To make sure that the
download of the channel list from USB to the TV is
executed properly, it is necessary to restart the TV and
tune to a valid preset if necessary.
Note: The “History list item” can not be downloaded from
USB to the TV. This is a “read-only” item. In case of
specific problems, the development department can ask
for this info.
How to Navigate
•In SAM, the menu items can be selected with the
“CURSOR UP/DOWN” key on the RC-transmitter. The
selected item will be highlighted. When not all menu items
fit on the screen, move the “CURSOR UP/DOWN” key to
display the next/previous menu items.
•With the “CURSOR LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected sub menu.
•With the “OK” key, it is possible to activate the selected
action.
How to Exit SAM
Use one of the following methods:
•Switch the TV set to STAND-BY via the RC-transmitter.
•Via a standard RC-transmitter, key in “00” sequence, or
select the “BACK” key.
5.2.3 Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV’s operation settings. A call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set. This helps them to diagnose
problems and failures in the TV before making a service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.
How to Activate
To activate CSM, press the following key sequence on a
standard remote control transmitter: “123654” (do not allow the
display to time out between entries while keying the sequence).
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.
•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 a in possibility to
do this.

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 supply.
Software versions
•Current main SW. Displays the built-in main software

5.3Service Tools
5.3.1 ComPair
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Lifestyle products. and offers the following:
1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short and effective way.
2. ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. You do not
have to know anything about I2C or UART commands
yourself, because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the uP
is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The (new) 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).

5.4Error Codes
5.4.1Introduction
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 are displayed:
•There is a simple blinking LED procedure for board level
repair (home repair) so called LAYER 1 errors, next to the
existing errors which are LAYER 2 errors (see Table 5-3
– LAYER 1 errors are one digit errors (via CSM).
– LAYER 2 errors are 2 digit errors (via SAM/SDM).
•In protection mode:
– From consumer mode: LAYER 1.
– From SDM mode: LAYER 2.
•In CSM mode: When entering CSM: error LAYER 1 will be
displayed by blinking LED. Only the latest error is shown.
•In SDM mode: When SDM is entered via Remote Control
code or the hardware pins, LAYER 2 is displayed via
blinking LED.
•In the “ON” state: with the RC commands “mute_06250X
_OK”, LAYER 2 errors are displayed via blinking LED.
•Error display on screen:
– In CSM no error codes are displayed on screen.
– In SAM the complete error list is shown.

Service portal.
Note: If you encounter any problems, contact your local
support desk.
5.4.2How 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
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 5.4.3 How to
Clear the Error Buffer.
•Via ComPair.
5.4.3How to Clear the Error Buffer
Use one of the following methods:
•By activation of the “Reset error buffer” command in the
SAM menu.
•With a normal RC, key in sequence “MUTE” followed by
“062599” and “OK”.
•If the content of the error buffer has not changed for 50+
hours, it resets automatically.
2010-Jul-01

5.4.4 Error Buffer
Service Modes, Error Codes, and Fault Finding
EN 25LC9.2L LA5.
In case of non-intermittent faults, clear the error buffer before
Table 5-2 Layer 1 error codes
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).
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.

•(*) 12V is necessary to start up the ARM, the ARM boots
the Stand-by processor.
– If 12V fails during normal operation or in stand-by, the
protection can be displayed via the “blinking LED”.
5.5The Blinking LED Procedure
5.5.1 Introduction
The software is capable of identifying different kinds of errors.
Because it is possible that more than one error can occur over
time, an error buffer is available, which is capable of storing the
last five errors that occurred. This is useful if the OSD is not
working properly.
Errors can also be displayed by the blinking LED procedure.
The method is to repeatedly let the front LED pulse with as
many pulses as the error code number, followed by a period of
1.5 seconds in which the LED is “off”. Then this sequence is
repeated.
Example (1): error code 4 will result in four times the sequence
LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After
this sequence, the LED will be “off” for 1.5 seconds. Any RC5
command terminates the sequence. Error code LED blinking is
in red color.
Example (2): the content of the error buffer is “129600”
After entering SDM, the following occurs:
•1 long blink of 5 seconds to start the sequence,
•12 short blinks followed by a pause of 1.5 seconds,
•9 short blinks followed by a pause of 1.5 seconds,
•6 short blinks followed by a pause of 1.5 seconds,
•1 long blink of 1.5 seconds to finish the sequence,
•The sequence starts again with 12 short blinks.
– If the mains cord is disconnected and reconnected
again, the ARM and Stand-by processor are not
booted, 12V can not be detected, and no indication is
possible.
5.5.2Displaying the Entire Error Buffer
Additionally, the entire error buffer is displayed when Service
Mode “SDM” is entered. In case the TV set is in protection or
Stand-by: The blinking LED procedure sequence (as in SDMmode in normal operation) must be triggered by the following
RC sequence: “MUTE” “062500” “OK”.
In order to avoid confusion with RC5 signal reception blinking,
this blinking procedure is terminated when a RC5 command is

Service Modes, Error Codes, and Fault Finding
5.6Fault Finding and Repair Tips
Notes:
•It is assumed that the components are mounted correctly
with correct values and no bad solder joints.
•Before any fault finding actions, check if the correct
options are set.
5.6.1 Software Protections
Most of the protections and errors use either the stand-by or the
micro processor as detection device. Since in these cases,
checking of observers, polling of ADCs, and filtering of input
values are all heavily software based, these protections are
referred to as software protections.
There are several types of software related protections, solving
a variety of fault conditions:
•Protections related to supplies: check of the 12V.
•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.
5. Stop bits = 1
6. Flow control = none
During the start-up of the TV set, the logging will be displayed.
This is also the case during rebooting of the TV set (the same
logging appears time after time). Also available in the logging
is the “Display Option Code” (useful when there is no picture),
look for item “DisplayRawNumber” in the beginning of the
logging. Tip: when there is no picture available during
rebooting you are able to check for “error devices” in the
logging (LAYER 2 error) which can be very helpful to determine
the failure cause of the reboot. For protection state, there is no
logging.
5.6.4Display option code
Caution: In case you have replaced the SSB, always check the
display option code in SAM, even if you have picture. With a
wrong display option code it is possible that you have picture,
but that in certain conditions you have unwanted side-effects.
5.6.5Trouble Shooting Tuner section
When there is no picture in analog RF mode:
1. Check whether picture is present in AV mode. If not, tuner
section is okay. Check video processing section.
2. Check if option settings are correct.
3. Check if 5 V supply is available at test points F256, F228,
F229 and F219, and if 33 V is available at test point F257.
4. Check if the I
5. Manually store a known channel and check if there is IF
output at tuner pin 11. If not, tuner is faulty.
6. Feed in 105 dBuV at tuner pin 11 and check whether there
is CVBS output from IF demodulator IC. If not, IF
demodulator might be faulty. Check components in this
area.
2
C lines are working correctly (3.3 V).
5.6.2 Hardware Protections
The only real hardware protection in this chassis is (in case of
an audio problem) the audio protection circuit that will trigger
the uP to switch “off” the TV.
Repair Tip
•It is also possible that you have an audio DC protection
because of an interruption in one or both speakers (the DC
voltage that is still on the circuit cannot disappear through
the speakers).
Caution: (dis)connecting the speaker wires during the ON
state of the TV at high volume can damage the audio
amplifier.
5.6.3Logging
When something is wrong with the TV set (f.i.the set is
rebooting) you can check for more information via the logging
in Hyperterminal. The Hyperterminal is available in every
Windows application via Programs, Accessories,
Communications, Hyperterminal. Connect a “ComPair UART”cable (3138 188 75051) from the service connector in the TV to
the “multi function” jack at the front of ComPair II box.
Required settings in ComPair before starting to log:
- Start up the ComPair application.
- Select the correct database (open file “Q549.3E LA”, this will
set the ComPair interface in the appropriate mode).
- Close ComPair
After start-up of the Hyperterminal, fill in a name (f.i. “logging”)
in the “Connection Description” box, then apply the following
settings:
1. COMx
2. Bits per second = 115200
3. Data bits = 8
4. Parity = none

5.6.8Start-up/Shut-down Flowcharts
On the next pages you will find start-up and shut-down
flowcharts, which might be helpful during fault finding.
POWER STATES
In this chassis, there are six possible power states as follows:
•Power OFF
•Power ON
•STANDBY
•SEMI-STANDBY
•Special Panel Mode
•PROTECTION
Figure 5-6 Power States
POWER OFF
In “Power OFF” mode, the system is completely switched “off”
from AC mains. When AC power is applied, the system checks
for last status. Depending on the last standby status stored in
the system EEPROM, this mode can then transit to “ON” or
“STANDBY” mode.
ON
This is the normal operating mode, indicated by the “on” LED.
All the power supply lines are available and depending on the
sub-mode, all the circuits in the system may be active. From
this mode it shall be possible to transit to “STANDBY” and
“PROTECTION” mode, or to “Power OFF” mode if AC mains
are switched “off”. The sub-modes are:
•Active Mode (Normal Consumer Mode)
•Service Modes
•Panel Modes
•Factory Modes
SPECIAL PANEL MODE
The Special Panel Mode is only used during manufacturing
process to program the system EEPROM. In this mode, the
SDA0 and SCL0 ports of MT5392 are set to high impedance
after SDM and PANEL pins are both detected as “low” during
start-up. This mode can be exited using a power recycle.
PROTECTION
This state is entered when an error has been detected at startup or in the “ACTIVE” mode. All switched power supply lines
are turned “off” with only +3V3stby remaining “on”; similar to
“STANDBY” mode. This state is indicated by the blinking red
front LED with the blinking sequence denoting the type of error
detected.
When the system enters the protection mode due to a critical
error, it should be turned “off” and the failure cause needs to be
resolved. The system will function normally again after
performing a power recycling once all protection causing
failures have been resolved.
START-UP SEQUENCE
There are two cases of start-up sequences, namely:
•AC On and
•Standby Wake-up.
See also Figure 5-7
.
AC ON
In the case of start-up from AC mains, all PSU voltages start to
turn “on” as the hardware default of the active “low” STANDBY
(controlled by Standby Controller STANDBY signal) signal to
the PSU is pulled “low” with respect to ground.
The MT5392 starts running boot loader once the hardware
reset circuit is released. The system will then check the last
standby status from the system EEPROM to determine
whether to complete the system start-up (load image, turn on
the audio, display etc) or proceed to standby and wait for wakeup command from user. The Standby Controller then proceeds
to verify the power status of the +12V and sends the system to
protection in case of any failures. Special Panel, SDM, and
PANEL modes are detected as well.
STANDBY WAKEUP
When the system receives a command to wake-up from
standby, the Standby Controller sets the STANDBY signal
“low” to turn “on” the switched power, and similarly detects for
the presence of +12V. The MT5392 waits for +3V3_SW to be
available before loading its image. The significance of this
voltage detection is due to the flash is also being powered by
the same mentioned voltage.
The following figure shows the start-up flowchart for both “AC
On” and “Standby Wake-up”:
STANDBY
The total power consumption of the system in this mode shall
be equal or less than 150 mW. This state is indicated by white
LED when AC mains is switched “on”. Only the standby
controller is operational in this state, where only +3V3stby
power supply is available. From this mode it shall be possible
to transit to the “ACTIVE” or “Power OFF” mode if AC mains are
switched “off”.
SEMI-STANDBY
The semi-standby state is required to perform the following
tasks:
•AmbiLight wakeup control
•PBS SemiStandby.

DC PROTECTION
The following figure shows the DC_PROT interrupt flowchart:
Figure 5-9 DC Protection flowchart
POWERDOWN SEQUENCE
The following figure shows the power-down sequence
flowchart:
•Upon detection, the power detection circuitry should switch
the low power DC/DC converters “off” and/or switch the
MT5392 in reset.
•The SW detection is done on the T8032 (built-in stand-by
microprocessor). The T8032 is fed by the stand-by voltage
and is less critical to power drops than the +12V and
derivatives.
•If T8032 detects a power drop, it shuts down the supplies
immediately (enter HW stand-by mode), waits for 5
seconds and restarts the system.
•If the power drop is caused by a mains voltage drop, the
system performs a cold boot which prevents a HW hangup
due to the power drop. At the restart, if power is readily
available again, the set will resume its function.
•If the power drop is caused by a failing supply, the failure
will be detected during the restart and the appropriate error
logging will be given.
•If the power drop is caused by mains voltage removal by
the customer, the set will restart but will ‘die’ during the 5s
wait time (specification of the power supplies).
Figure 5-10 Power-down flowchart
•Power detection circuitry should be quick enough to rapidly
detect any powerdip which is large enough to jeopardize

the functionality of the set.

5.7Software Upgrading
5.7.1 Introduction
It is possible for the user to upgrade the main software via the
USB port. This allows replacement of a software image in a
stand alone set, without the need of an E-JTAG debugger. A
description on how to upgrade the main software can be found
in the DFU.
Important: When the NAND-Flash must be replaced, a new
SSB must be ordered, due to the presence of the security keys!
(copy protection keys, MAC address, ...).
Perform the following actions after SSB replacement:
1. Set the correct option codes (see sticker inside the TV).
2. Update the TV software => see the DFU for instructions.
3. Perform the alignments as described in chapter 6.
4. Check in CSM if the HDMI key, MAC address.. are valid.
For the correct order number of a new SSB, always refer to the
Spare Parts list on the Philips Service web portal!
5.7.2 Software Upgrade
SW versions can be divided in three types:
•SW that can not crash the working of the set.
– EDID NVM. If the download fails, the set is still running
and the download can start again.
– Main NVM: If the download fails the default NVM value

Note: Figures below can deviate slightly from the actual
situation, due to the different set executions.
General: The Service Default Mode (SDM) and Service
Alignment Mode (SAM) are described in chapter 5. Menu
navigation is done with the CURSOR UP, DOWN, LEFT or
RIGHT keys of the remote control transmitter.
6.1General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
•Power supply voltage: 120 - 230 V
•Connect the set to the mains via an isolation transformer
with low internal resistance.
•Allow the set to warm up for approximately 15 minutes.
•Measure voltages and waveforms in relation to correct
ground (e.g. measure audio signals in relation to
AUDIO_GND).
Caution: It is not allowed to use heatsinks as ground.
•Test probe: Ri > 10 Mohm, Ci < 20 pF.
•Use an isolated trimmer/screwdriver to perform
alignments.

•Go to the SAM and select “Alignments”-> “White point”.
White point alignment LCD screens:
•Use a 100% white screen as input signal and set the
following values (in SAM mode):
– “Color temperature” to “Cool”.
– “Whitepoint red”, “Whitepoint green”, and “Whitepoint
blue” values to “127”.
– “Red BL offset” and “Green BL offset” values to “8”.
With a color analyzer:
•Measure with a calibrated, contactless (max. 25 mm
distance) color analyzer in the centre of the screen.
Consequently, the measurement needs to be done in a
dark environment.
•Adjust one or two registers (so holding one of the White
point registers R, G or B on 127) to obtain the “Cool” x,y
values (see Table 6-1
). Tolerance: dx: ± 0.004, dy: ± 0.004.
•Repeat this step for the “Normal” and “Warm” color
temperatures.
•When finished press “OK” on the RC and then press
“Store” (in the SAM root menu) to store the aligned values
into the NVM.
•Restore the initial picture settings after the alignments.

Not applicable.
6.3Software Alignments
Put the set in SAM mode (see chapter 5. Service Modes, Error
Codes, and Fault Finding). The SAM menu will now appear on
the screen. Select ALIGNMENTS and go to one of the sub
menus. The alignments are explained below.
The following item can be aligned:
•Whitepoint.
To store the data:
•Press OK on the RC before the cursor is moved to the left.
•In main menu select “Store” and press OK on the RC.
•Press MENU on the RC to switch back to the main menu.
•Switch the set to stand-by mode.
For the next alignments, supply the following test signals via a
video generator to the RF input:
•LATAM models: an NTSC M TV-signal with a signal
strength of at least 1 mV and a frequency of 61.25 MHz
(channel 3).
6.3.1 White Point
•Set “Active control” to “Off”.
•Choose “TV menu”, “TV Settings” and then “Picture” and
set picture settings as follows:

Dynamic backlight Off
Dynamic ContrastOff
Colour EnhancementOff

y0.2780.2910.319
Without a color analyzer, you can use below default values.
This is the next best solution. The default values are average
values coming from production (statistics).
•Select a “Color Temperature” (e.g. “Cool”, “Normal”, or
“Warm”).
•Set the “Whitepoint Red”, “- Green” and “- Blue” default
values according to the values in the “Tint settings” table.
•When finished press “OK” on the RC, then press “Store” (in
the SAM root menu) to store the aligned values into the
NVM.
•Restore the initial picture settings after the alignments.

6.4Option Settings
6.4.1 Introduction
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 specific
ICs (or functions) is made known by the option codes.
Notes:
•After changing the option(s), save them with the STORE
command.
•The new option setting becomes active after the TV is
switched “off” and “on” again with the mains switch (the
EAROM is then read again).
6.4.2 Dealer Options
For dealer options, in SAM select “Dealer options”.
See Table 6-4
6.4.3 (Service) Options
Select the sub menu's to set the initialisation codes (options) of
the model number via text menus.
See Table 6-4
.

“Option code overview”.
Example: The options sticker gives the following option

C
numbers:
•25604 00386 00235 56068
•08395 05120 00000 00000
The first line (group 1) indicates hardware options 1 to 4.
Example: option no. “2” contains the “cabinet type”.
The second line (group 2) indicates software options 5 to 8.
Example: option no. “5” contains the “display code”.
Every 5-digit number represents 16 bits (so the maximum value
will be 65536 if all options are set).
When all the correct options are set, the sum of the decimal
values of each Option Byte (OB) will give the option number.
See Table 6-3
for the options. Always refer to the sticker in the
TV-set as leading.
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. This results in another Display Code thus in
another Option code. Refer to chapter 3. Precautions, Notes,
and Abbreviation List.
6.4.4 Opt. No. (Option numbers)
Select this sub menu to set all options at once (expressed in
two long strings of numbers).
An option number (or “option byte”) represents a number of
different options. When you change these numbers directly,
you can set all options very quickly. All options are controlled
via eight option numbers.
When the NVM is replaced, all options will require resetting. To
be certain that the factory settings are reproduced exactly, you
must set both option number lines. You can find the correct

SSB: SRP List Explanation
1 . 1 . Introduction
Example
SRP (Service Re ference Protocol) is asoftw are too l that creates a list w i th all refer e n c es to signal lines. The list contains
references to the signals w i thin all schemat ics of a PWB. It replaces the text refe r ences currentl y p r inted next t o the signal
names in the s
chematics. These printed refe rences are created man ually an d are t h e r efore n o t guar an teed to be 100 %
correct. In additio n , in the current crowded schema t ics there is often none or ver y little pl ace for these references.
Either there will be an SRP
reference list for a schematic, or there will be printed references in the schematic.
1.2. Non-SRP Schematics
There are several different signals available in a schematic:
1.2.1.Power Supply Lines
All power supply lines are available in the supply line overview (see chapter 9). In the schematics (see chapter 10) is not
indicated where supplies are coming from or going to.
It is however indicated if a supply is incoming (created elsewhere), or outgoing (created or adapted in the current schematic).
+5V+5V
Outgoing Incoming
1.2.2. Normal Signals
For normal signals, a schematic reference (e.g. B14b) is placed next to the signals.
signal_name
B14b
1.2.3. Grounds
For normal and special grounds (e.g. GNDHOT or GND3V3 etc.), nothing is indicated.
1.3. SRP Schematics
SRP isa tool, which automatically createsa list with signal references, indicating on which schematic the signalsare used.
A reference is created for all signals indicated with an SRP symbol, these symbols are:
+5V+5V
Power supply line.
namename
Stand alone signal or switching line (used as lessas possible).
namename
Signal line into a wire tree.
namename
Switching line into a wire tree.
name
Bi-directional line (e.g. SDA) into a wire tree.
name
Signal line into a wire tree, its direction depends on the circuit (e.g. ingoing for PDP, outgoing for LCD sets).
Remarks:
• When there is a black dot on the “signal direction arrow” it is an SRP symbol, so there will be a reference to the signal
name in the SRP list.
• All references to normal grounds (Ground symbols without additional text) are not listed in the reference list, this to keep
it concise.
•
Signals that are not used in multiple schematics, but only once or several times in the same schematic, are included
in the SRP reference list, but only with one reference.
Additional Tip:
When using the PDF service manual file, you can very easily search for signal names and follow the signal over all the
schematics. In Adobe PDF reader:
• Select the signal name you
want to search for, with the “Select text” tool.
• Copy and paste the signal name in the “Search PDF” tool.
• Search for all occurrences of the signal name.
• Now you can quickly jump between the different occurrences and follow the signal over all schematics. It is advised to
“zoom in” to e.g. 150% to see clearly, which text isselected. Then you can zoom out, to get a
n overview of the complete
schematic.
PS. It is recommended to use at least Adobe PDF (reader) version 6.x, due to better search possibilities in this version.
