I just picked up and old NBA Jam Cabinet that I am wanting to restore. The main board appears to be working but there is no game sound just some beeps. The cabinet is in overall decent shape. The problem I think I should tackle first is the monitor. The picture is very, very dim and appears to be no color at all. I'm thinking of doing a cap kit on it, but I don't know what or where to buy from. The monitor is a WG I believe and measures 27" diag. Any pointers on where to start would be appreciated. Thanks!!!
