All I have is this picture to go on - as it is from the person whom is restoring the game for me. There appears to be a line or two of horizontal DMD fade. It doesn't appear to be a huge issue. But I have a couple of questions as possible options: is it repairable and what would it take? If I get a color dmd for this WH20, will the fade still show up? and what's the approximate cost to replace this Williams DMD?
