5.4 Service Tools
5.4.1 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 I
2
C 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 μP
is working) and all repair information is directly available.
4. ComPair features TV software upgrade 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.
Figure 5-6 ComPair II interface connection
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!
