I bought NIB Ghostbusters Premium in June. Around November/December started noticing intermittent flipper issues where during a game flippers would just stop working. Both at same time always. Would go into service menu, test them, they would always work on test, then would return to game and they would work. Sometimes they would work for rest of the time I played while other times this would happen over and over and over. Problems have just worsened over time. Now game is almost unplayable as happens so regularly as to make it more frustrating than it is worth. Called Stern tech support and they could only offer possible solutions. The game was 5 months old and not cheap! I am not versed in the tech of pinball machines and cannot diagnose this issue myself. Even the local guy who repairs pinball machines in my area is at a loss. Anybody else have this issue? Help!!!!!!!! First pinball purchase ever and maybe last. Thanks.
