So I picked up a Batman forever today and it has some dmd issues. Most of the time the screen is half lit and dim like in the pic. Some of the screens light the bottom half and it’s bright like it’s supposed to be. Sometimes it just works altogether but never for long.
I’m just looking for a little advice on where to begin. I’ve not worked on many sega pins. Is this most likely a power supply issue?
Any help will be greatly appreciated. Thanks
