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.
