SCHEMATIC DIAGRAM
[1] DESCRIPTION OF SCHEMATIC DIA-
GRAM
VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on exclusive AC adaptor
and the stable supply voltage of AC 230V.
Signals are fed by a colour bar signal generator for servicing pur-
pose and the above voltages are measured with a 20k ohm/V
tester.
INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
1. The unit of resistance “
Ω” is omitted.
    (K=k
Ω=1000 Ω, M=MΩ).
2. All resistors are 
± 5%, unless otherwise noted.
    (K= 
± 10%, F= ± 1%, D= ± 0.5%)
3. All resistors are 1/16W, unless otherwise noted.
CAPACITOR
1. All capacitors are 
µF, unless otherwise noted.
    (P=pF=
µµF).
2. All capacitors are 50V, unless otherwise noted.
CAUTION:
This circuit diagram is original one, therefore there may be a
slight difference from yours.
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.
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH “
” (
) 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.
