Area 51 Site 4 color issues

[petsematary125]

I'm still in Lewisville for a few days and have another Site 4 board that I would like to unload. I don't recall it having graphic issues. I capped the motherboard on it.

Hey, thanks! It's seeming more like this is a board+monitor issue as opposed to just the PCB (it looks OK on one of my other arcade monitors), so I'm going to try to resolve it with the resistor workaround like that other user. I noticed that even when the screen is adjusted to total black, the distorted color parts STILL show up. Very odd.

That said, if you happen to have any other JAMMA gun game PCBs (original A51, Lethal Enforcers, Maximum Force, etc) that you're looking to sell, maybe shoot me a message since I'm interested in getting some other games for this cab.

I do have an Area 51 dual board, but I think it was just standard Area 51, not the dual game, and it's old school hard drive. also I'd have to see what your Site 4 issue is, I'm not familiar with it. I wish I could unload both of these boat anchors finally. LOL

I resolved this issue by building a pass through board with a 10kohm pot on each color signal (effectively the same method that Kino used). Cleared up the problem completely. Still wonder what's the root cause because the Site 4 PCB displays fine as-is on one of my other monitors.
