DESCRIPTION OF SCHEMATIC DIAGRAM
VOLTAGE MEASUREMENT CONDITION:
INDICATION OF RESISTOR & CAPACITOR:
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.
