I did some work on a bad Off brand SNES power supply to see if I could get it working. I then plugged a SNES mini into it to see if it worked. Bad move now the SNES mini won’t power on. It’s been sitting around for years just recently I possessed the skill I think to be able to fix it. Just not sure where I should start. Wondering if anyone had a SNES mini schematics sheet? Or does anyone have any suggestions on what it could of blown?
