Well hi I had no +5 so I bought another PS and had no +5 either so then I did then re flow on the solider joints every thing else looked good new capacitor for +5 seemed to pull up the +5 but when the board was plugged in the +5 would drop off to like 1 volt then the led would go out. I'm wondering about the iso. Well now I was testing the fuse leds with it on and touched something lol and now it just blows a fuse and pretty sure that is one of the +5 fuses thats why ready to put in an 8 liner.
 
Did you replace the BR1 bridge rectifier (the large square component on the board). If you did, you may need to resolder the top pads to the legs. Because the pads are so large it is difficult to get the solder to flow to the top pads.

Which fuse is blowing? That will give you a clue which part of the circuit is bad.

Thanks guys no I didn't do the bridge rectifier that is the problem pretty sure, the +5 fuse is blowing 2nd one in on the board runs right to the bridge rectifier. I just put a switcher in for now found a schematic online.
