picked up this machine, cleaned the track ball. Played it for days and all of a sudden I have a scrambled screen. The sound and everything else works.
Please help... I'm broken hearted

That just looks like you need to adjust the horizontal hold on the monitor. What monitor is it?

You have a sync problem. If the horizontal H-freq isn't working try pulling out the video wires and blowing them off and plugging them back in.

Thanks so much for the images. I unplugged and reconnected them but only blew them out with my mouth. I have to get air in a can tomorrow.

I made a quick youtube video because you shouldn't need a can of air maybe a wire is broke? You did try adjusting the horizontal H-freq on the chassis all the way back and forth first right?

Thanks for the vid...I thought I almost had it with more H Freq adjustments. I was starting to make out some graphics... like the high scores and missile command graphics.

You have two! lol I found the PDF for that monitor http://pdf.textfiles.com/manuals/ARCADE/A-J/Electrohome%20G07%2013in%20&%2019in%20Color%20Raster%20[Service%20&%20Ops]%20[English].pdf

You have vertical and horizontal sync so you should try the v-hold pot too.
