Safety measures
• Some internal parts in this product contain high voltages
and are dangerous. Be sure to take safety measures dur-
ing servicing, such as wearing insulating gloves.
• Note that positions indicated below are dangerous even
after the power is turned off because an electric charge
remains and a high voltage continues to exist there.
Before starting any repair work, perform discharge by con-
necting a discharge resistor (5k-ohms/10W) between ter-
minals at following positions. The time required for dis-
charging is about 30 seconds.
1. C502 on INPUT (1) P.C.B..
2. C523 on INPUT (1) P.C.B..
Refer to “PRINTED CIRCUIT BOARDS: INPUT (1)
P.C.B.” .
