Update on 8ball. Well I had the j4 pins replaced on the MPU board.Turned it on ..... 7 flashes, game powers up all good. Played four or five games, playing good....until the credit knocker went thump as normal. Lost power to displays and ball wouldnt kick out. This kept on happening, until finally it would lose power during a game, as previously discussed earlier in this thread. What do i do now?
