Hello pinside, I need your help once more.
Last weekend we went and bought a working batman forever. It was in very nice condition, nice playfield, everything working, snappy flippers. About everything you need when buying a pinball machine.
However, today luck changed. A colleague turned the machine on, and instead of the normal display, it showed up all garbled like in the attached picture.
It was not blanking out or resetting or had any problems whatsoever before today, so something must have failed. I've tried reseating all connectors and ribbon cables without luck. What could it be?
