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

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.
