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 120V.
Signals are fed by a color 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=k
Ω
=1000
Ω
, M=M
Ω
).
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
µ
F, unless otherwise noted.
(P=pF=
µµ
F).
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.
AVIS DE SECURITE IMPORTANT:
