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.
In 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 can access the I2C bus of the television. ComPair can send and
receive I2C commands to the micro controller of the television. In this way, it is
possible for ComPair to communicate (read and write) to devices on the I2C
busses of the TV-set.
•
Manually
(by asking questions to you): Automatic diagnosis is only possible if the
micro controller of the television is working correctly and only to a certain extend.
When this is not the case, ComPair will guide you through the faultfinding tree by
asking you questions (e.g.
Does the screen give a picture? Click on the correct
answer: YES / NO
) and showing you examples (e.g.
Measure test-point I7 and
click on the correct waveform you see on the oscilloscope
). You can answer by
clicking on a link (e.g. text or a waveform picture) that will bring you to the next
step in the faultfinding process.
By a combination of automatic diagnostics and an interactive question / answer
procedure, ComPair will enable you to find most problems in a fast and effective way.
