I have no clue if anyone here can help. but I recently picked up a power supply for a tattoo machine and when I plugged in in DOH! I had it set to 110V not 220V (I live in Korea)

All I get is a loud hum from the machine, and nothing at all once I switched it back to 220V (there's a digital screen and it does not turn on)

It will be a MAJOR problem to replace the unit and I'm at a loss as to what happened or if I can fix it. THere was no you-can't-miss-it burning transformer smell and upon tearing the unit apart no noticeable burns, or any damage at all.

It's a simple setup using a tranformer, a curcuit board with a couple of resistors and capacitors, and all is attached to some switches and dials and the digital screen.

Any suggestions? I would be much appreciated!!

If you are *very* lucky, then there will be a thermal fuse which may have saved the PSU. Otherwise you may need to replace the transformer and possibly other circuitry
