I think it may be the rings on the neck. After all the arcade machine did take a nasty tumble! I used the back of a soldering iron (which I see has the same effect as a drill as I've read). I was able to get a small amount of purple removed from the corner. But it looks like the issue is more serious than a degauss can fix.
I guess I would have to adjust the neck. I do not want to do this myself due to the obvious risk of shock. There are a few TV repair places near by, but of course the arcade isn't exactly portable. Unless they made house calls. Is adjusting the neck simple? I'd assume it's something delicate.
The center of the screen looks pretty perfect. However the edges are worse. There seems to be a gain or loss of color. The 'Parental Advisory Warning' screen I believe is supposed to be black (I think), shows large red and green rings (with only a bit of blue ring). On a white screen you surprisingly see not much at all, just the lower right corner.
You can see my images attached below: arcade-colors.png = Parental Advisory screen, arcade-colors2.png = Sega screen, arcade-colors3.png = Level Screen, sega-compare.png = Before and after my attempted degaussing. It only helped a bit.
Any help would be greatly appreciated, thanks for your help so far!

Update: At first I only saw 'focus' and 'brightness' on the back of the monitor. But then I looked at the side and there are about 14 little white switches/knobs and 5 bigger black knobs. Maybe these will help? Looks like only 2 screws hold the board into place, it has a ribbon cable. I'd be happy if I could drag the board outward so I can take a look at the knobs easily. As of now they are facing the wood of the cabinet and not easily accessible at all. Maybe these will help adjust things?
Some items say normal things like 'R cut off' and 'G cut off' etc, but then there are things that say 'Sub Cont', 'ABL', 'H. H. 24', 'H. H. 15', 'PIRA', etc. Not sure if any of this is useful.
