56FW-53H 66FW-53H 76FW-53H 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 2. SEMICONDUCTOR HEAT SINKS SHOULD BE noted. REGARDED AS POTENTIAL SHOCK HAZARDS 3. All capacitors are µF, unless otherwise noted (P= µµF). WHEN THE CHASSIS IS OPERATING. 4. The capacitor with Part No. RC-FZ9XXXBMNJ is designed to with stand IMPOTANT SAFETY NOTE: 63V. PARTS MARKED WITH « ! » ( ) ARE 5. The capacitor with Part No. IMPORTANT FOR MAINTAINING THE SAFETY RC-FZ4XXXBMNJ is designed to with stand OF THE SET. BE SURE TO REPLACE THESE 50V. SAFETY NOTE: 1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE REPLACING PARTS. PARTS WITH SPECIFIED ONES FOR MAINTAINING THE SAFETY AND PERFORMANCE 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.
