Battery Damage
Small spot of acid damage from batteries that leaked at some point. The components in this area will be removed the board cleaned and protected from further damage. The batteries were removed and no other signs of acid damage were found. NVRAM (non-volitale RAM) from Pinball Electronics was installed that no longer needs the batteries to hold settings. This will prevent damage to the board from leaking batteries.
Display Issue
The Alpha-numeric portions of the display were turning on segments that should not be displayed. It appeared that segments B and D were always being displayed when there was a character being displayed. On closer inspection some letters did not have the issue such as K, pointing towards a short.
With all the harnesses removed from the display driver board the lines for segments B and D were found to be shorted together. No visible short could be found on the board so Chip U14 was pulled to test out of the board. Under U14 a tiny solder bridge was found which fixed the display problem
