1. Turn off the power supply. Using a 10 , 10 W resistor, connect both ends of power supply
capacitors (C822, C833) 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 respectto supply voltage 230/240 V.
