it was working fine in my tekken cab, i took it out and put it in another cab the picture was grainy and had some lines. i put the tekken board in and same thing. so i pulled the chassis and put another one in and it wouldn't power on no neck glow, i checked the power going in and the fuse both are good. i tried a second chassis and same thing no power. i then put the original back in and it now has no power also. what else would make it not power on? 3 different chassis don't work so it has to be something else.
