Hello all. I have a tested good tkg3 pcb that I bought recently, and put a mikes arcade pin to edge connector on. I got it to work once, and then when I transferred it to another cabinet it put a green screen. It now does this in every single machine it's in. (One with a Nintendo to Jamma adapter it gives a white screen) the board has a braze high score kit on it. I'm not sure where to proceed. My monitors are good, power supplies are good, so I'd hate to think my board was ruined by a product from mikes arcade. I really don't want to spend hundreds more paying for a repair. Also it doesn't play blind, the only thing I can get is the boot jump sound on one of my cabinets.
