So I've recently got a dead nJoy 500W PSU. ERL39 transformer (real),2SC3220 transistors, sleeved cables and pretty thick heatsinks, all nice stuff (except caps which are ChengX but that's not the point for now). It even has a pretty beefy bridge rectifer. (although no heatsink on it)
It came to me with two bad Fhy 1000uF 200V caps. I replaced them with some 680uF 200V caps and bypassed the PFC connector, and temporarily replaced the glass fuse with a 100W lightbulb.
On powering on, I only get a flash of the light bulb and a quick click (about a split second) and no fan movement or nothing.
Is there anything I should remove? I have a feeling I haven't fully disabled the PFC circuitry.
I really wish to fix this PSU since it's pretty much full of parts. Of course, after fixing it (means when it will finally power on fine and voltages will be within range) it will probably get back some new 1000uF 200V caps (hope I can snatch some Pannies or Rubies for it to go with the black PCB) and a nice recap on the whole secondary.
Oh, and it has dual rails, and I'm not even kidding. The PCB literally has two separate 12v spots where the wires go.
