SCHEMATIC DIAGRAMS

Description:
VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on the stable supply voltage of AC 230V. 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
(K=k=1000 , M=M).
1. The unit of resistance "" is omitted.
2. All resistors are ± 5%, unless otherwise noted. (J= ± 5%, F= ± 1%, D= ± 0.5%)
3. All resistors are 1/16W, unless otherwise noted.
4. All resistors are Carbon type, unless otherwise noted.
