Procedure 3 Connector Check and Cable Check

The LCD module is connected to the system board by an LCD/FL cable. The FL inverter board is also connected to the system board by an LCD/FL cable. And the FL is connected to the FL inverter board by the HV cable. The connectors may be disconnected from the system board or the FL inverter, or they may be damaged. Disassemble the computer following the steps described in Chapter 4, Replacement Procedures.

If the connection is loose, reconnect firmly and restart the computer. If there is still an error, go to Procedure 4.
