I took out the Lethal Enforcers board, top mounted the monitor, plugged in CPS2 with SSF2X and the screen looks good enough, but all the white are almost a deep yellow now.
What can I do to help fix this? This is the back of my monitor, and I’ve tried messing with the pots I do see, but I don’t see any color/etc pots. It has a little controller that has pots for depth/width/etc but none for color.
Based on RGB values, yellow is a product of full Red and Green (#FFFF00)… So since white requires full blue, I’d say that the either the blue signal is deficient from the board, or the monitor is not receiving it. How are your Blues?
The pot that controls them, or that I assume controls them, doesn’t seem to have any effect on the monitor. I can crank the reds up (it can go complete red almost) but the green is more subtle, and then the pot on the board by itself on the right has no effect on color at all (or anything). I guess my blue is shot? Thats a bummer considering it was working perfectly on the game previous to this… maybe I knocked something and messed it up. Here is a screen shot.

I’ll probably end up living with it as arcade monitors are ridiculously overpriced. I also get blue horizontal lines when I crank up the brightness (which turns everything blue, but not in a good way.)
Check the wiring. There may be a loose or bad contact or bad wire in the blue line.
Thats what I’m thinking. This brand of monitor uses a “controller”, and the vertical sync pot is insanely sensitive. I’ll check the wiring tomorrow, thanks for the heads up!
I checked the wires and everything looks ok, but hopefully it might be a bad JAMMA connection. What are the chances it’s the A/B board doing this? I turn the pot on the back for blue and… nothing happens. I get faint blue lines horizontally in the image.
Isolate. Test the monitor with another board first if you have any handy (does that Kethal Enforcers board still work?).
It could be a bad pin on the A/B connection. (I don’t know the pinout.)
Have you tried the color test screen from the service menu?
Boy I feel stupid.
The molex connector is broken and the covering someone put on it to “hold” the blue wire in place was flopping all about.
What is this part called so I can get another one?
Dunno (Pics might help…). It may be easier to replace the entire connector.
