Step 1:
Replace the front panel control PCB.
Step 1:
Set the multimeter to diode test setting, test the voltage drop
of four secondary diodes on the output rectifier board.
If it is over 0.2V, it is normal.
If it is lower than 0.1 V, the secondary diode is defect.
Replace the secondary PCB/Module.
Step 2:
If the main relay on the main control panel is not working,
and the driving is abnormal, the power source will not work.
Replace the main control PCB.
