I BEFORE REPAIR AND ADJUSTMENT

Turn off the power supply and short-circuit both ends of power supply condensers (C601,C602,8200uF) at

resistance (about 1052, SW) in order to discharge the charged voltage. Avoid short-circuit with a screwdriver or the like,
otherwise the transistors or diodes may break down.
Before turning on the power supply after completion of repair, slowly apply the primary voltage by using a voltage
regulator to make sure that the current consumed is free of abnormality. The current consumed at 60H2/50Hz in no
signal mode is shown below with respect to supply voltage 110V/120V/220V/240V.
