I picked up a Neo Geo - 4 slot the other day with 4 games and a 111-1. It's in good condition with a perfect monitor. The only problem is the sound during gameplay has static and screeching over the sounds of the game. The Neo Geo intro screen sounds perfect. I cleaned the slots with contact cleaner and a toothbrush and I cleaned the games, same problem. I ordered a cap kit from Ian today, besides that is there anything else that would cause that problem?
