Hello everyone, I am new to this forum and have a problem with a Nintendo Punch-out arcade. When I bought the machine it was not displaying at all, I pulled apart the PCB clean and re-seated all the roms. I plugged it back in and rejoice, it worked apart from the fact Glass Joe is a pile of Pixels. I suspected which could be a voltage issue so I have turned up the 5v and still no resolve. Any ideas ??
