My screen is likely the issue, I swapped with another WOZ and narrowed it down to the screen (swapped SD cards, etc). I have a new screen but it seems like there is some firmware that might need to be deployed on it? Maybe I need one of their USB connection kits so I can do that? I swapped the SD card in to the new screen but I just get the screen "diag report" and nothing else.
LTG Pinballomatic is there a trick to getting a new screen to work?
