1. Before Repairs
1. Turn off the power supply. Using a 10 , 10 W resistor, connect
both ends of power supply capacitors (C701, C703 and C702,
C704) 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 respecttosupply
voltage 230/240 V.
