Trying to repare O2 PWR supply. APS-90(SONY).
When i turn ON it's power, it becomes on and again OFF. I confirmed that PWM control PCB is faulty. I replaced all ICs with new but problem is same. Any Help please.... does any one have it's Schematic pls.
Thanks in advance.

Dear Joshi, sounds like a capacitor problem but please also check the power control drivers like transistors
