I wanted to ask a quick display issue question on a GTB System 80. I looked at the pin repair guides and wiki and didn't see anything that was quite like the issue I have.
I don't have any issues with missing segments/digits, but I have a intermittent flickering with some extra numbers displaying on my credit and P3/P4 displays. Sometimes it's fine, other times it goes crazy for a few seconds flashing extra characters on those displays.
I've cleaned the edge contacts, reflowed/checked the display boards. Is it a connector related issue possibly?
