Good evening all,
I am trying to repair an ATX power supply out of a Dell XPS ONE A2010. This is an all in one desktop computer. The power supply is a Delta DPS-200PP-164. I have been unable to find a schematic or anything helpful online. Repairing PCB boards is a hobby and I am slowly teaching myself. I can use a DMM and have an ESR meter, but no other test equipment.
I am looking for any advice on where to further investigate.
Here is what I've determined so far:
-5v output is OK
-12v output jumps around between 1v – 4v
-There is a “whining” or “hissing” noise when the power supply is turned on.
-There is an audible “clicking” noise coming from the PSU. It sounds like possibly a relay clicking on and off every few seconds.
I am not familiar or experienced enough with ATX power supplies to know where to investigate futher without a schematic. Any help would be appreciated.
Thanks,
Amos
