CHAPTER 5. SCHEMATIC DIAGRAM
[1] DESCRIPTION OF SCHEMATIC DIAGRAM
1. 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 gener-
ator for servicing purpose and the above voltages are measured with a 20k ohm/V tester.
2. 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 MAIN-
TAINING THE SAFETY AND PERFORMANCE OF THE SET.
