Error codes
When an error causes the PDP to switch “OFF”, an error code
is put into an EEPROM on the Logic Board. You can read out
the contents of the error code memory with the ComPair tool.
5.2.1
How to Connect the ComPair Tool
•
Carefully disconnect the LVDS cable from CN01 on the
Logic Board.
•
If necessary connect a PSU with a voltage of 3.3V to drive
the LOGIC board.
•
Connect the cable from the ComPair tool to connector
CN01 of the LOGIC board.
•
Turn on the ComPair tool.
•
Launch the ComPair software.
•
Read out the error buffer.
