![]() Hey Guys, I have problem with a power supply board which I think is not starting up since there is no 5V.
The board has a PWM Controller LD7576AGR (IC901) and might be bad according another post although there is 105V on the photocoupler pins. I changed the caps in the high voltage zone hoping for a quick fix but this is more complicated and not sure where go from her. Any thoughts appreciated.
