DESCRIPTION OF SCHEMATIC DIAGRAM
SAFETY NOTE:
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 OPER-
ATING.
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH "A" ( )
ARE IMPORTANT FOR MAINTAINING THE
SAFETY OF THE SET. BE SURE TO REPLACE
THESE PARTS WITH SPECIFIED ONES FOR
MAINTAINING THE SAFETY AND PERFORM-
ANCE OF THE SET.
NOTE:
1 . The unit of resistance "ohm" is omitted
(K=1000 ohms, M=Magaohm).
2. All resistors are 1/8 watt, unless otherwise
noted.
3. All capacitors are U.F, unless otherwise noted
(P=^F).
4. The capacitor with Part No. RC-FZ9XXXBMNJ
is designed to withstand 63V.
WAVEFORM MEASUREMENT
CONDITIONS:
Colour bar generator signal of 70 dB from RF
input.
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.
CAUTION:
This circuit diagram is original one, therefore
there may be a slight difference from yours.
