(8pins)
There are two power supply as the second power supply of the transformer.
One is a power supply for power IC(3pin), and another is a power supply for the control(8pin).
Please connect first of all and confirm the power supply for the control when you do the energizing examination after it completes of
the repair.
For power IC(3pins)
Please never do the energizing examination in a power supply of power IC alone.
Moreover, when the control system breaks down, power IC is occasionally damaged.
