2. Before Repair and Adjustment
1. Turn off the power supply. Using a 10
, 10W resistor, connect both ends of power
supply capacitors (C102-105, 127) in order to discharge the voltage.
2. Before turning the power supply on, after completion of repair, slowly apply the
primary voltage by using a power supply voltage controller to make sure that the
consumed current at 50 Hz in NO SIGNAL mode should be shown below with
respect to supply voltage 230 V.
