My cousins own a Mortal Kombat II arcade machine. One day after attempting to use a special modification to connect a computer monitor to it, they turned it on and found that the screen was distorted. They thought the colors needed to be calibrated but this did not help at all. it turns out that when the machine tries to display red, it displays green, when it tries to display green it is blue, and when it tries to display blue, it displays red (I think). After reading other posts and the service manual, I believe that the graphics controller (JAMMA?) connector is broken/connected wrong. I also think that if this isn't the problem, we can swap the red signal output to go to blue, the green signal to go to red, and blue to go to green. Does this all sound about right?
update: when I said the picture is distorted, I actually meant the picture is fine but the colors are wrong.
update: they put everything back the way it was originally after trying the modification
