Hey Guys,
I bought a Donkey Kong Cab to restore I got it fairly cheap beause it was not working. I cleaned it up and all then tried plugging it in to see what the problem was. As soon as I plug it in I get this loud hum noise out of the speaker and the video on the monitor is all scrambled. Do you think this is a PCB issue? I am not handy with soldering and what not on boards so I was just going to get a working used PCB to swap the other board with. Do you think this is the correct action???
