I have a 19K7901 which never looked right - had issues with brightness washing out all the colors, colors being weird, etc. and I could never adjust it to look correct. After plenty of reading I figured a new cap and fly kit would help. I finished the work last night, reassembled and it really hasn't changed much - now where it should display black it's blue, the whites are more yellow, slight diagonal lines. An hour of adjusting and that's the best it gets. So, any ideas as to what to look at? Could it be the neck board, tube, or chassis?
I don't have a lot of experience with arcade displays and the only other one I have is a 19k4901 - can I swap the chassis to that tube to see if it's a problem with the tube itself or at least confine the problem to the neck board or chassis? Can a tube have a problem?
If it matters, the 7901 is in a Road Blasters and the 4901 is in a Pole cockpit.
