Problems and Solving Tips (related to CSM)
Note: Below described problems are all related to the TV
settings. The procedures to change the value (or status) of the
different settings are described above. New value(s) are
automatically stored.
5.3.1
Picture Problems
Picture too dark
1. Press SMART PICTURE several times on the RC. In case
the picture improves, increase the "Brightness" or the
"Contrast" value.
2. Check in CSM lines BRIGHTNESS and/or CONTRAST. If
the value of line BRIGHTNESS is low (< 10) or the value of
line CONTRAST is low (< 10), increase them. The new
value(s) are automatically stored (in "personal" pre-set) for
all TV channels.
Picture too bright
1. Press SMART PICTURE several times on the RC. In case
the picture improves, decrease the "Brightness" or the
"Contrast" value.
2. Check in CSM lines BRIGHTNESS and/or CONTRAST. If
the value of line BRIGHTNESS is high (> 40) or the value
of line CONTRAST is high (> 50), decrease the
"Brightness" or the "Contrast" value. The new value(s) are
automatically stored (in "personal" pre-set) for all TV
channels.
White line around picture elements and text
1. Press SMART PICTURE several times on the RC. In case
the picture improves, decrease the "Sharpness" value.
2. Check in CSM line SHARPNESS. Decrease the
"Sharpness" value. The new value is automatically stored

ComPair

5.4.1
Introduction
ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote control),
which allows faster and more accurate diagnostics. ComPair
has three big advantages:
ComPair helps you to quickly get an understanding on how to
repair the chassis in a short time by guiding you systematically
through the repair procedures.
ComPair allows very detailed diagnostics (on I2C level) and is
therefore capable of accurately indicating problem areas. You
do not have to know anything about I2C commands yourself
because ComPair takes care of this.
ComPair speeds up the repair time since it can automatically
communicate with the chassis (when the microprocessor is
working) and all repair information is directly available. When
ComPair is installed together with the SearchMan electronic
manual of the defective chassis, schematics and PWBs are
only a mouse click away.
5.4.2
Specifications
ComPair consists of a Windows based faultfinding program
and an interface box between PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
(or RS232) cable.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector.
The ComPair faultfinding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:
•
Automatic (by communication with the television):
ComPair can automatically read out the contents of the
entire error buffer. Diagnosis is done on I2C level. ComPair
