VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on 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 & CAPACI-
TOR:
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=
10
-6
µ
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 HAZ-
ARDS WHEN THE CHASSIS IS OPERATING.
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH “ Α ” ( ) A R E
