5.2Error 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.

Figure 5-1 Extension cable kit ALiS PDP

• 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.
