Service Tools

ComPair
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 I
2
C 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 uP
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 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.
How to Connect
This is described in the chassis fault finding database in
ComPair.
Figure 5-5 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
damaged!
How to Order
