DESCRIPTION OF SCHEMATIC DIAGRAM
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.
IMPOTANT SAFETY NOTE:
PARTS MARKED WITH «
IMPORTANT FOR MAINTAINING THE SAFETY
OF THE SET. BE SURE TO REPLACE THESE

MAINTAINING THE SAFETY AND PERFORMAN-
CE OF THE SET.
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
HAZARD OF ELECTRIC SHOCK.
NOTE:
