I just picked up a Maverick and certain scenes on the DMD get jumpy or shaky and other scenes display perfectly. In test mode it shows perfect and doesnt shake. Any ideas where to start?
I did notice that the cpu rom is version 4.04 and the display roms are 4.00, not sure if that matters.

I reseated both cables and nothing changed. Here is a quick video I took of the issue.

The previous owner did mention something about a latch chip. I will have to download the schematics and see what chips those are.

I'm going to send the driver board to coinop cauldron to get tested just to make sure it isnt the issue. I sent him a video and he said it looks like the high voltage of the dmd might be the cause. If I have to replace the dmd I may pick up the one from pinballsp. It's brand new and if I took the time I could color it like colordmd, and it's only 300. Dr Pinball is or was working on a direct non color replacement but doesnt look like they are for sale yet. At least I have some options now.

I have a friend that has the dmdextender in his Frankenstein and it looks great. I thought about going that route as well but looks like its sold out right now.

It's a bit far of a drive. I'm fine sending it out because if it is not working he can fix it.

I had a very similar issue. Had the controller board tested and it was fine so the issue was with the plasma screen. I finished building a dmd extender last night to replace the plasma display. It came out really nice.

I think it was around $260 for everything.

This is the one I used.

I used almost the same colors but went with black instead of brown. It was just too much brown.
