2 Before Repair and Adjustment

1. Turn off the power supply. Using a 10Ω , 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 50/60 Hz in NO SIGNAL mode should be shown below with respect to
supply voltage 220 V-240 V.
