TROUBLE SHOOTING TABLE
No power supply (Front LED is not ON)
Is power cable properly connected to the main unit?
Is F701 normal?
Is F702 normal?
Reconnect the wire harness, FFC, etc. in the set, and repeat
the check.
Connect the power cable properly, and turn on the power.
Replace F701, and turn on the power. If the fuse is still
blown, replace VA701, D701, Q705 and Q706, and repeat
Replace F702, and turn on the power. If the fuse is still
blown, replace D701 and IC701, and repeat the check.
Remove the faulty part or short-circuit, and repeat the check.
Check IC902 and its peripheral
