Quoted from DumbAss:Check the fuses on the AV board.
Don’t just check, replace it. I have had fuses that check ok but do that on DMD’s. Not fully blown. Replace and it maybe fixed. Then I would swap DMD’s with another machine that you know works. (Put the mm dmd in another machine) Then swap the ribbon cables. If not that then swap the AV Board with another WPC95 game if you have one (SS and CV in your profile). Put the MM AV board in the machine that works so if you have voltage issues in mm won’t damage good board. If board does not work in other machine that is your issue. You will find what your issue is if you go through that. The WPC95 AV board you can buy from rotten dog as they just got them again. Last year impossible to find. Have someone fix your original AV board as the WB originals have a premium. Then use the rottendog as your spare board once you get the original back. Having a spare is key for WPC 95 games. I believe you a have bad a AV board but most expensive fix. Let us know! FYI color DMD’s take stress off of that board as they use 12v power supply instead of high voltage. Let someone with experience fix that board. Some great guys that specialize on them on pinside.
