I have a Wells Gardner 19K7901 that displays no RED color in my Tetris. I tried a different monitor and it works perfectly so it is definitely the monitor. I tried re soldering the video input posts, swapping some of the "red" parts on the neckboard...with no luck. I tried messing with the red pots on the neckboard and only if I crank the red cutoff all the way up do I see a tiny hint of red on the screen. Any thoughts?
