I have recently received a broken PSU. I am posting on this forum to see if anyone has any suggestions as to what the best way to go about locating the problem would be. I would like to eventually convert the PSU to a bench power supply if I can get the PSU running. When I connect the PSU to the power cable and then connnect the PG through hole to a ground through hole, the PSU makes a very small whining noise however I do not receive any power from any of the outputs and the fan does not turn on. At the begging of this little project I removed the solder on all of the cables to the PCB because I did not think I’d need them for the project I was planning on doing but then I find out many people keep those cables for bench power supply conversions. In hind-sight this may have been a bad idea but I’m hoping that I can still get the PSU running anyways.
Hopefully this was enough info.
Thanks,
Joel
