Top row of display has the top right segment of every character stuck on. It's random when it happens. And sometimes they aren't all on. Just some faintly lit. Seems very random.
When they are stuck on, you can remove the ribbon cable to the sound board and the display acts as it should. Plug it back in, and the stuck segments are back.
I have swapped out the ribbon cables. I have swapped displays with a Pinscore LED. I'm thinking it's probably the CPU, but unplugging the sound board to correct the issue is throwing me off.
Anyway, any help would be awesome!!
