SCHEMATIC DIAGRAM
IMPORTANT SAFETY NOTICE:
BE SURE TO USE GENUINE PARTS FOR SE-
CURING THE SAFETY AND RELIABILITY OF
THE SET.
PARTS MARKED WITH "
å
" AND PARTS
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 HAZ-
ARDS 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
AC230V~240V/50Hz 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.
