Hello, I'm quite new to all this arcade building and need a bit of help with a problem i have encountered. A couple of months ago I bought a SF2 game board and set about re-wiring an old cabinet. The monitor in the cabinet was burnt in and the motherboard was faulty so i decided to use a Mitsubishi computer monitor I had aquired, it has BNC connectors and will accept a composite sync or h&v. Having finished it all works apart from I'm getting some sort of interference /wavey pattern running through the picture! has anyone got any thoughts as to what might cause this? could it be caps on the game board or is it more likely mains hum? any suggestions are welcome.
Thanks
