I have fixed a couple of mine with the same symptoms. The issue with mine was corroded tracks under the LCD which detected by swelling of the solder mask where the tracks were damaged. I had to rerun some of the tracks to get them working again.

I have two units one with partial and one with a couple full columns out.. It would be nice if we could locate a replacement display to resolve the issue with a modern solution. The game machines have them... Greg
