Electrical Adjustments

1. BEFORE MAKING ELECTRICAL ADJUST-
MENTS

Read and perform these adjustments when
repairing the circuits or replacing electrical parts
or PCB assemblies.

CAUTION
•  Use an isolation transformer when performing

any service on this chassis.

•  Before removing the anode cap, discharge

electricity because it contains high voltage.

•  When removing a PCB or related component,

after unfastening or changing a wire, be sure
to put the wire back in its original position.
Inferior silicon grease can damage IC’s and
transistors.

•  When replacing IC’s and transistors, use only

specified silicon grease (YG6260M). Remove
all old silicon before applying new silicon.
