Just unfolded my Shadow - it has been folded since April as I was renovating parts of my basement to create a home office. It worked perfect when I folded it but now the display is all garbled and the start button flashed but won't start a game when it is pushed. It did start one game with a grabled display before I turned it off due to the garbled display - now it won't start a game. The CPU LEDs (WPC-S) don't indicate a problem and I reseated all the cables. I get the single sound "nong". Not sure where to start here. A few solenoid's fire at at startup (which I think is normal), however, the mini-playfield paddle doesn't move (which I think it should) and the mini playfield drop targets (solenoid) attempt to reset multiple times (which I don't think it did before).
Any help would be greatly appreciated. Diagnosing board issues isn't my strong point. Thanks.
