SCHEMATIC DIAGRAM

[1] DESCRIPTION OF SCHEMATIC DIAGRAM
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 purpose 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=kΩ=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.
