NOTE : 1. Since a voltage is applied to the

Main Power PCB and PFC PCB
heat sinks while the set is
operating, do not touch the heat
sinks.

2. If the PFC PCB insulation sheet

is not installed when assembling,
the PFC PCB fuse will blow.

3. After the power cord plug was

pulled out , do not pull out the
connector on the Main Power
PCB until the Green LED (D531:
Discharge check LED) turns off.
