Hooked up a K7000 monitor and it seems very bright and has diagonal white lines showing. I have adjusted the pots but that doesn't seem like the problem. Also, when the chassis is rocked or vibrated when someone is playing the game, the entire screen flickers green. I checked to see if the remote adjustment board was rubbing against something and that wasn't it. PCB is a NBA Jam. Thoughts?

Thanks!

Try turning the SCREEN down on the flyback.

Check the video cable input header pins and the neckboard for bad solder joints.
 
also check the transistors on the neck board. make sure they don't have cold solder joints or have broke lose from the traces and are wobbling around and shorting to something.

and a cap kit would not hurt it any if it hasn't had one.
