5.4 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.
