CAUTION:
This circuit diagram is original one, therefore there may be a
slight difference from yours.
SAFETY NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC
OUTLET BEFORE REPLACEING PARTS.
2. SEMICONDUCTOR HEAT SINKS SHOULD BE
REGARDED AS POTENTIAL SHOCK HAZARDS
WHEN THE CHASSIS IS OPERATING.
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH “
å
” ( ) ARE
IMPORTANT FOR MAINTAINING THE SAFETY OF
THE SET. BE SURE TO REPLACE THESE PARTS
WITH SPECIFIED ONES FOR MAINTAINING THE
SAFETY AND PERFORMANCE OF THE SET.
VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on
exclusive AC adaptor and the stable supply voltage
of AC 120V. Signals are fed by a color bar signal
generator for servicing purpose and the above
voltages are measured with a 20k ohm/V tester.
INDICATION OF RESISTOR & CAPACI-
TOR:
