Safety Measures
• Some internal parts in this product contain high voltages and are dangerous. Be sure to take safety measures during servicing, such as
wearing insulating gloves.
• C971 on the SMPS (2) P.C.B. is 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 connecting a discharge resistor (5k-ohms/10 W) between terminals of the capaci-
tor. The time required for discharging is about 30 seconds.
After the repair work, also perform discharge in the same manner.
