I recently acquired a Williams System 7 machine with display issues. I purchased a X Pin display board with LEDs and although improved, I still have these problems:
1. Player 1 and 2 displays always have small number “7” in the lower left corner of all positions.
2. The center (horizontal) segment of the balls remaining display is always on.
I’ve switched LEDs and that’s not the issue.
I’d appreciate any help
