I adjusted the potentiometers and can modify the color saturation and brightness. However when I get the image crisp, the brightness is really low.

I'll go ahead and install the Caps and see what happens.

Thanks for your help

Got what I thought was a good on a Marvels Superheros Cabinet.
Inside of it I found this mystery monitor. The 25K7121

The issue I'm having seem to be with colors & brightness.
Will a Cap Kit fix these issues?

Is the same as a  K7000?
If so my hope is that I can replace the Caps and Voila the monitor will be brighter and colors more defined.

Is this a realistic expectation. Or should I pitch it? Start over with another monitor

The image on my chasis is the only clue I have found to the boards Identity.

Getting to the point I need a support group to help troubleshoot some of these peskie little glitches that come about.

Been listening to the show for awhile now. Have a small pinball arcade of my own. And a few video machines.

Shout out from St. Louis.
