SCHEMATIC DIAGRAM
IMPORTANT SAFETY NOTICE:
BE SURE TO USE GENUINE PARTS FOR SE-
CURING THE SAFETY AND RELIABILITY OF THE
SET.
PARTS MARKED WITH "
SHADED (IN BLACK) ARE ESPECIALLY IMPOR-
TANT FOR MAINTAINING THE SAFETY AND
PROTECTING ABILITY OF THE SET.
BE SURE TO REPLACE THEM WITH PARTS OF
SPECIFIED PART NUMBER.
SAFETY NOTES:
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.
NOTES:
1. The unit of resistance "ohm" is omitted (k=1000
ohm, M=1 Meg ohm).
2. All resistors are 1/8 watt, unless otherwise noted.
3. The unit of capacitance "F" is omitted ( µ = µ F, p= µµ F).
4. The values in parentheses are the ones in the PB
mode; the values without parentheses are the ones
in the REC mode.
VOLTAGE MEASUREMENT CONDITIONS:
1. DC voltages are measured between points indi-
cated and chassis ground by VTVM, with
AC110~240V, 50/60Hz supplied to unit and all
controls are set to normal viewing picture unless
otherwise noted.
2. Voltages are measured with 10000 µ V B & W or
colour noted.
WAVEFORM MEASUREMENT CONDITIONS:
10000 µ V 87.5 percent modulated colour bar signal is
fed into tuner.
CAUTION:
This circuit diagram is original one. Therefore there
may be a slight difference from yours.
