I own a Capcom Flipper Football that has a couple of rows and one column out for as long as I have owned it. After the game has been running for a while, usually one of the rows comes to life.
This game uses an extra large DMD (256x64) and I have searched for a replacement for several years and never found one - NOS or used.
Does anyone out there do DMD repair? I think this one could be helped if placed in the right hands.
