SCHEMATIC DIAGRAM
[1] DESCRIPTION OF SCHEMATIC DIAGRAM
1. VOLTAGE MEASUREMENT CONDITION:
1. Voltages at test points are measured at the supply voltage of AC
100V/CROSS 10V-240. 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. he unit of resistance “
Ω” is omitted.
(K=k
Ω=1000 Ω, M=MΩ).
2. All resistors are
± 5%, unless otherwise noted.
(J=
± 5%, F= ± 1%, D= ± 0.5%)
3. All resistors are 1/10W, unless otherwise noted.
4. All resistors are Carbon type, unless otherwise noted.
: Solid
: Cement
: Oxide Film
: Special
: Metal Coating
CAPACITOR
1. All capacitors are
µF, unless otherwise noted.
(P=pF=
µµF).
2. All capacitors are 50V, unless otherwise noted.
3. All capacitors are Ceramic type, unless otherwise noted.
(ML): Mylar (TA): Tantalum
(PF): Polypro Film (ST): Styrol
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.
