I am looking for some help on my MCR Tron machine. I recently did the high score saves satans hollow upgrade. While doing it I decided to replace all of the original ribbon cables. Now two of the games have strange color patterns. It is most obvious with the light cycle game. I have blue lines across the screen in a grid pattern. All of the games and sounds work perfectly other than the lines in the light cycle and a few missing colors in the IO Game.

I reseated all of the new parts and ribbon cables with no changes. I contacted High score saves and they think it may be something with the new ribbon cables. I did a continuity test on the back of each board to confirm that the cables were connected. Everything was about .5 ohms. Does anyone have any ideas on what I can check next? I know enough to get myself in trouble, but I figure that is the only way to learn. Thanks in advance.
