1. Turn off the power supply. Using a 109, 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 respectto supply voltage 230/240 V.
Power supply voltage AC 230 V AC 240 V
Consumed current 50 Hz 70 ~ 250 mA
