Create a CSM dump on an USB stick
There will be CSM dump to a plugged in USB-stick upon
entering CSM-mode. An extended CSM dump will be created
when the "OK" button on RC is pressed in CSM while a USB
stick is plugged in. A direct CSM flash dump will be created
when the buttons "red + 2679" on the remote control are
pressed in CSM while a USB stick is plugged in.
How to Exit
To exit CSM, use one of the following methods:
• Press the MENU/HOME button on the remote control
transmitter.
• Press the POWER button on the remote control
transmitter.
• Press the POWER button on the television set.
5.3 Service Tools
5.3.1 ComPair
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics 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).
How to Connect
This is described in the ComPair chassis fault finding database.

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 will be
blown!
How to Order
ComPair II order codes:
• ComPair II interface: 3122 785 91020.
• ComPair UART interface cable: 3138 188 75051.
• Program software can be downloaded from the Philips
Service web portal.
Note: For this chassis, "Pgammar" and "T-con NVM"
programming (VCOM alignment) are added to ComPair.

Error Codes
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.
2
• Failing I C device.
2
• General I C 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.
