Hints: Most of the surface mount electroyltics have leaked out on the
boards. Might not be worth fixing as the boards are no longer
available and were multi-layer and no Canon support any longer on the
unit. Only hope is to take it apart and start checking.
That model does not come up in my database as us ever having a service
manual for it as a Canon authorized servicer in the 90's. It is
possible it is one of the models towards the end of Canon's attempt to
stay in the Camcorder market that they kept as factory depot only,
which means little chance for a service manual.
