LC-13B4U-S
LC-13B4U-B
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 & CAPACI-
TOR:
