Up until recently I had been putting up with some strange display issues on my Doctor Who (Bally, 1992) and Judge Dredd (Bally, 1993). Each game worked well enough but there were artifacts on the display that should not normally be present. Since I was about to sell the Doctor Who, I decided to finally figure out the issues with both display driver boards. I also figured it would be a good opportunity to write a general instructional post about integrated circuit replacement on a circuit board.
