SCHEMATIC DIAGRAM
Description:
VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on exclusive AC adaptor and 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.
