SERVICE PRECAUTION:
THE AREA ENCLOSED BY THIS LINE ( )
IS DIRECTLY CONNECTED WITH AC MAINS
VOLTAGE.
WHEN SERVICING THE AREA, CONNECT AN
ISOLATING TRANSFORMER BETWEEN TV
RECEIVER AND AC LINE TO ELIMINATE HAZ-
ARD OF ELECTRIC SHOCK.
DESCRIPTION OF SCHEMATIC DIAGRAM
NOTE:
1. The unit of resistance «ohm»is omitted (K=1000
ohms. M= Megaohm).
2. All resistors are 1/8 watt. unless otherwise noted.
3. All capacitors are mF, unless otherwise noted
(P= mmF).
4. The capacitor with Part No. RC-FZ9XXXBMNJ
is designed to with stand 63V.
5. The capacitor with Part No. RC-FZ4XXXBMNJ
is designed to with stand 50V.
SAFETY NOTE:
1. DISCONNECT THE AC PLUG FROM THE AC
OUTLET BEFORE REPLACING PARTS.
2. SEMICONDUCTOR HEAT SINKS SHOULD BE
REGARDED AS POTENTIAL SHOCK HAZARDS
WHEN THE CHASSIS IS OPERATING.
IMPORTANT SAFETY NOTE:
PARTS MARKED WITH «
