5.1
Life Timer
During the life time cycle of the TV set, a timer is kept (called
“Op. Hour”). It counts the normal operation hours (not the
Stand-by hours). The actual value of the timer is displayed in
SDM and SAM in a decimal value. Every two soft-resets
increase the hour by + 1. Stand-by hours are not counted.
Software Identification, Version, and Cluster
The software ID, version, and cluster will be shown in the main
menu display of SDM, SAM, and CSM.
The screen will show: “AAAAB-X.YYY”, where:
• AAAA is the chassis name: T913E x.yyy.
• B is the region indication: E = Europe, A = AP/China, U =
NAFTA, L = LATAM.
• X is the main version number: this is updated with a major
change of specification (incompatible with the previous
software version). Numbering will go from 1 - 99 and
AA - ZZ.
- If the main version number changes, the new version
number is written in the NVM.
- If the main version number changes, the default settings
are loaded.
• YYY is the sub version number: this is updated with a minor
change (backwards compatible with the previous
versions). Numbering will go from 000 - 999.
- If the sub version number changes, the new version
number is written in the NVM.
- If the NVM is refreshed, the software identification,
version, and cluster will also be written to NVM.
Test Points
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. However, several key
ICs are capable of generating test patterns, which can be
controlled via ComPair. In this way it is possible to determine
which part is defective.
Perform measurements under the following conditions:
• Service Default Mode.
• Video: Colour bar signal.
• Audio: 3 kHz left, 1 kHz right.
5.2
Service Modes
The Service Mode feature is split into five parts:
• Service Default Mode (SDM).
• Service Alignment Mode (SAM).
• Factory Mode.
• Customer Service Mode (CSM).
• Computer Aided Repair Mode (ComPair).
Display Option Code Selection
When after an SSB or display exchange, the display option
code is not set properly, it will result in a TV with “no display”.
Therefore, it is required to set this display option code after
such a repair.
To do so, press the following key sequence on a standard RC
transmitter: “062598” directly followed by MENU and “xxx”,
where “xxx” is a 3 digit decimal value of the panel type: see
column “Display Code” in Table 6-3. When the value is
accepted and stored in NVM, the set will switch to Stand-by, to
indicate that the process has been completed.
During this algorithm, the NVM-content must be filtered,
because several items in the NVM are TV-related and not SSB
related (e.g. Model and Prod. S/N). Therefore, “Model”
and “Prod. S/N” data is changed into “See Type Plate”. In case
a call centre or consumer reads “See Type Plate” in CSM
mode.
SDM, SAM and the Factory mode 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).
• Make alignments (e.g. White Tone), reset the error buffer
(SAM and Factory Mode).
• 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.
5.2.2
Purpose
Set the TV in SDM mode in order to be able to create a
predefined setting for measurements to be made. In this
platform, a simplified SDM is introduced (without protection
override and without tuning to a predefined frequency).
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
mP (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).
Specifications
• 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 favourite”, “Skipped” or
“Locked” presets/channels.
– Automatic storing of Personal Preset or Last Status
settings.
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).

How to Activate CSM
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).
After entering the Customer Service Mode, the following items
are displayed.
Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV’s operation settings.The call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set.This helps the call centre to
diagnose problems and failures in the TV set before making a
service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
Contents of CSM
• 1.1 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.
• 1.2 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.
Specifications
• Ignore “Service unfriendly modes”.
• Line number for every
line (to make CSM language independent).
• Set the screen mode to full
screen (all contents on screen is visible).
2012-Apr-27
After leaving the Customer Service Mode, the original
settings are restored.
Possibility to use “CH+” or “CH-” for channel surfing, or

ComPair
5.5.1
Description
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:
1. ComPair helps to quickly get an understanding on how to
repair the chassis in a short and effective way.
2. ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. No
knowledge on I2C or UART commands is necessary,
because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
micro processor is working) and all repair information is
directly available.
4. ComPair features TV software up possibilities.
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. A description on how to upgrade the main
software can be found in the DFU or on the Philips website.
5.5.2
Philips continuously tries to improve its products, and it’s
recommend that the TV software is updated when updates are
available. Software update files can be obtained from the
dealer or can be downloaded from the following websites:
http://www.philips.com/support
Preparing a portable memory for software upgrade
The following requirements have to be met:
1. A personal computer connected to the internet.
2. An archive utility that supports the ZIP-format (e.g. WinZip
for Windows or Stufflt for Mac OS).
3. A FAT formatted USB memory stick (preferably empty).
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.
Note:
1. Only FAT/DOS-formatted memory sticks are supported.
2. Only use software update files that can be found on the
http://www.philips.com/support web site.

Error Codes
5.6.1
Introduction
Error codes are required to indicate failures in the TV set. In
principle a unique error code is available for every:
• Activated (SW) protection.
• Failing I2C device.
• General I2C error.
The last five errors, stored in the NVM, are shown in the
Service menu’s. This is called the error buffer.
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is displayed at the left side and all other errors shift one
position to the right.
An error will be added to the buffer if this error differs from any
error in the buffer. The last found error is displayed on the left.
An error with a designated error code never leads to a
deadlock situation. It must always be diagnosable (e.g. error
buffer via OSD or blinking LED or via ComPair).
In case a failure identified by an error code automatically
results in other error codes (cause and effect), only the error
code of the MAIN failure is displayed.

Note:
• Do not remove the USB flash drive during the software
update.
• If a power failure occurs during the update, do not remove
the USB flash drive from the TV. The TV will continue the
software update as soon as the power comes up again.
• If an error occurs during the update retry the procedure or
contact the dealer.
• We do not recommend downgrading to an older version.
• Once the upgrade is finished, use the PC to remove the TV
software from the USB portable memory.

How to Read the Error Buffer
You can read the error buffer in three ways:
• On screen via the SAM/SDM/CSM (if you have a picture).
Example:
– ERROR: 000 000 000 000 000: No errors detected
– ERROR: 013 000 000 000 000: Error code 13 is the
last and only detected error
Content and Usage of the One-Zip Software File
Below you find a content explanation of the One-Zip file, and
instructions on how and when to use it. Only files that are
relevant for Service are mentioned here.
• EDID_clustername.zip: Contains the EDID content of the
different EDID NVMs. See ComPair for further instructions.

Error codes
Caution:
• Do not change these, without understanding the function of
each setting, because incorrect NVM settings may
seriously hamper the correct functioning of the TV set!
• Always write down the existing NVM settings, before
changing the settings. This will enable you to return to the
original settings, if the new settings turn out to be incorrect.

The error code buffer is cleared in the following cases:
• By using the CLEAR command in the SAM menu
• By using the CLEAR command in the Factory mode:
• By using the following key sequence on the remote control
transmitter: “062599” directly followed by the OK button.
• If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.

Audio Amplifier
The Class D-IC U6002 has a powerpad for cooling. When the
IC is replaced it must be ensured that the powerpad is very well
pushed to the PWB while the solder is still liquid. This is needed
to insure that the cooling is guaranteed, otherwise the Class
D-IC could break down in short time.
5.8.8
CSM
When CSM is activated and there is a USB memory stick
connected to the TV, the software will dump the complete CSM
content to the USB memory stick. The file (Csm.txt) will be
saved in the root of the USB memory stick.
Displaying the Entire Error Buffer

Loudspeakers
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!
Fault Finding and Repair Tips
Note:
2012-Apr-27
No Picture via HDMI input
Check if HDCP key is valid. This can be done in CSM.
Additionally, the entire error buffer is displayed when Service
Mode “SDM” is entered.
5.8
Unstable Picture via HDMI input
Check (via ComPair or factory mode) if HDMI EDID data is
properly programmed.
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 RC
command terminates the sequence. Error code LED blinking is
in red color.
Example (2): the content of the error buffer is “12 9 6 0 0” 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.
5.7.2
No Picture
When you have no picture, first make sure you have entered
the correct display code. See paragraph 6.4 Option Settings for
the instructions. See also Table 6-3.
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.
The Blinking LED Procedure
Load Default NVM Values
It is possible to upload the default values to the NVM with
ComPair in case the SW is changed, the NVM is replaced with
a new (empty) one, or when the NVM content is corrupted.
After replacing an EEPROM (or with a defective/no EEPROM),
default settings should be used to enable the set to start-up and
allow the Service Default Mode and Service Alignment Mode to
be accessed.
How to Clear the Error Buffer
5.7
NVM Editor
In some cases, it can be convenient if one directly can change
the NVM contents. This can be done with the “NVM Editor” in
SAM mode. With this option, single bytes can be changed.
In this chassis only “layer 2” error codes are available and point
to problems on the SSB. They are triggered by LED blinking
when CSM is activated. Only the following layer 2 errors are
defined:
Layer-2 error code
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.

Attention: In case the SSB is replaced, always check the Panel
Code in CSM, even when picture is available. Performance
with the incorrect display option code can lead to unwanted
side-effects for certain conditions.

In case you have a colour analyser:
• Measure with a calibrated (phosphor- independent) color
analyser (e.g. Minolta CA-210) in the centre of the screen.
Consequently, the measurement needs to be done in a
dark environment.
• Adjust the correct x,y coordinates (while holding one of the
White point registers R, G or B on max. value) by means of
decreasing the value of one or two other white points to the
correct x, y coordinates (see Table 6-1 White D alignment
values). Tolerance: dx:  0.010, dy:  0.010.
• Repeat this step for the other colour Temperatures that
need to be aligned.
• When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
• Power supply voltage: 90 - 264 VAC, 50/ 60  3 Hz.
• 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 heat sinks as ground.
• Test probe: Ri > 10 M, Ci < 20 pF.
• Use an isolated trimmer/screwdriver to perform
alignments.

Introduction
6.5.1
SSB’s of this chassis are identified by a “715” code on the SSB.
715Axxxx-Nnn-MMM-OOOO
• 715 main category, Printed Wiring Board
• Axxxx sub category, sequential coding number
• Nnn Version code
• N Development number
• nn Production number
• MMM Mounting variation code
• OOOO Optional variation code
Make sure when replacing an SSB the SSB identification codes
match the replacement board.
The microprocessor communicates with a large number of I2C
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
MT5366 ICs is made known by the option codes.
Notes:
• After changing the option(s), save them by pressing the OK
button on the RC before the cursor is moved to the left,
select STORE 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).

Reset of Repaired SSB
A very important issue towards a repaired SSB from a Service
repair shop (SSB repair on component level) implies the reset
of the NVM on the SSB.
A repaired SSB in Service should get the service Set type
“00PF0000000000” and Production code “00000000000000”.
Also the virgin bit is to be set. To set all this, you can use the
ComPair tool or use the “NVM editor” and “Dealer options”
items in SAM (do not forget to “store”).
After a repaired SSB has been mounted in the set (set repair
on board level), the type number (CTN) and production code of
the TV has to be set according to the type plate of the set. For
this, you can use the NVM editor in SAM. The loading of the
CTN and production code can also be done via ComPair
(Model number programming).
In case of a display replacement, reset the “Operation hours
display” to “0”, or to the operation hours of the replacement
display.
