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 OPERATING.
IMPORTANT SAFETY NOTICE:
BE SURE TO USE GENUINE PARTS FOR SECURING THE
SAFETY AND RELIABILITY OF THE SET.
PARTS MARKED WITH  "
å
" (                      ) ARE
IMPORTANT FOR MAINTAINING THE SAFETY OF THE
SET.  BE SURE TO REPLACE THESE 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 ACMAINS VOLTAGE.
WHEN SERVICING THE AREA, CONNECT AN
ISOLATING TRANSFORMER BETWEEN TV RECEIVER
AC LINE TO ELIMINATE HAZARD OF ELECTRIC SHOCK.
CAUTION:
This circuit diagram is original one,  therefore there may
be a slight difference from yours.
NOTES:
1. The unit of resistance "
" is omitted.
(K = k
 = 1000 
,  M = M
).
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 indicated and
chassis ground by VTVM, with AC 220 ~ 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 coloour
signal.
WAVEFORM MEASUREMENT CONDITIONS:
10000
µ
V, 87.5% modulated colour bar signal is fed into
tuner.

BLACK) ARE ESPECIALLY IMPORTANT FOR
MAINTAINING THE SAFETY AND PROTECTING
ABILITY OF THE SET.
BE SURE TO REPLACE THEM WITH PARTS OF
SPECIFIED PART NUMBER.
