Hey, guys! Quick question, what's the deal here? (Video below)

The display just blinks the start up jargon (display version A5.00 etc...) when the game is turned on and it never leaves that screen. I can get into the Portals menu, and a full game can be played.

I have a Tommy and was curious if I could bring the display and display board over (The whole kit and caboodle) and put into The Simpsons, but I have limited knowledge of the Whitestar stuff. I understand if they were compatible you'd have to swap the roms and be careful of orientation, but both boards look fairly similar.

Thanks for any help or suggestions.

So, the display power boards are compatible between games? The displays are the same size. I'm just not trying to blow anything up hahaha

Rad, thanks. Any clue whats causing this? I'm at a loss.

Haven't done any work. On it. The big ribbon cable was used to troubleshoot a display issue on Tommy (found out the ribbon cable wasn't the issue on Tommy) Upon putting the ribbon back in TSPP the issue showed up. It was the only thing I unplugged from the board.

I know the Display rom has been reseated and that hasn't changed anything. I haven't tried the game roms yet.

Yeah, red is on 1. The DMD on Tommy still works it just looks like it has a visible refresh rate. We have tried that cable in TSPP and have gotten the exact same result. So I'm not convinced it's the cable to be honest.
