2 Before Repair and Adjustment
TOP PREVIOUS NEXT
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
50/60 Hz in NO SIGNAL mode should be shown below withrespect to supply voltage 220 V-
240 V.
