1. Turn off the power supply. Using a 10Ω , 10W resistor, connect both ends of power supply capacitors (C537, C538, C707, C717, C718, C765, C768, C769, C770, C771, C776, C894, C907) 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 60 Hz in NO SIGNAL mode should be shown below with respectto supplyvoltage 120 V.

   Power supply voltage	AC 120V
   Consumed current	60 Hz	400~1200 mA
