I have a williams teachers pet that no matter how much i try i can NOT figure out how to get the game working?! I press the left flipper upon startup the backglass lights up it says ball 1 on the backglass & all the score reels reset to zero BUT the only thing that works on the playfield is the eject holes not even the outhole works. I have cleaned all jones plugs & made sure they were all seeded correctly. What am i missing?. The only time the game comes to life is if i hold together the tilt switch on the bottom left of the cabinet (next to the score motor) then the left flipper will trigger and the game will turn off on but that is it. Please help. This game worked before it was moved for 2 years
