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 "Ω" is omitted.
(K = kΩ = 1000 Ω, M = MΩ).
2. All resistors are 1/8 watt, unless otherwise noted.
3. The unit of capacitance "F" is omitted.
(µ = µF, P = µµF).
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 110 ~ 240V, 50/60Hz supplied to unit
and all controls are set to normal viewing picture unless otherwise
noted.
2, Voltages are measured with 10000µV B&W or coloour signal.
WAVEFORM MEASUREMENT CONDITIONS:
10000µV, 87.5% modulated colour bar signal is fed into tuner.
