Picked up a LW3 a while back and I've been trying to figure out a DMD issue. Whenever the DMD is on the main score-keeping screen it shows distortion or some kind of partial mirroring on the bottom few rows. However, other screens that use the same bottom rows of dots display just fine. The issue is not constant but reoccurring, sometimes switching between working properly and not within the same game. Oddly, this only occurs on the scoring screen and never during any of the other screens or animations.

Things I've tried:
- Checked DMD in diagnostic mode, looks fine in test pattern.
- swapped the DMD ribbon cable with a spare one - no change.

I don't have a spare DMD so I haven't been able try swapping it out.

Suggestions, thoughts, ideas, conspiracy theories?

chadh is working on a game code rewrite that will require new CPU and Display roms, so if you can wait a bit longer for new ROMs I'd wait for those.

I've also read about an issue in Freeplay mode by my machine has never done it.
