Your monitor has a degaussing coil around it (the black tube looking thing surrounding the screen). It needs to be wired to the chassis and to the degauss button, but I don't know how that's done on your cab so I'll let someone more familiar with it explain.
The other alternative is to buy an external degaussing coil, which is a handy tool to have anyway: https://www.arcadepartsandrepair.com/store/tools-supplies/tools/crt-13-degaussing-coil/
You plug it in and hold it in front of the screen while pressing the button and it will clear up the discoloration.

Your cab seems to have a degauss coil plugged in (the red cable).
You can confirm the coil is okay with a multi-meter.
Its just a loop of wire that goes around the back of the tube. A short pulse of AC current is driven through it and it does its woo woo magic with the tubes polarity or w/e.
So unplug the cabinet, unplug that cable and put your meter in continuity mode then put one probe on each side with the cables connector if it beeps the cable is fine (has continuity)
Also your chassis seems to have a PTC (the little black box next to the demag connector on the chassis) that automatically does the Degaussing? Someone with a tad more experiance can confirm that off hand from your photos.
If so these PTC's can sometimes die with age/hours because they run hot while the monitor is on. They only send current to the coil at the time the chassis gets AC power.
That was my understanding at least.
You can also manually wire the chassis up to run demag off that demag button on the front of the cab something to do with removing or bypassing the PTC. That goes outside my scope of experience though.

i got a snk26 too probably from same person because mine looks the same but its stuck at my friends warehouse atm till i can get it out.
I got the handheld degaussing ring - worked like a champ! thanks for the recommendation.Your cab seems to have a degauss coil plugged in (the red cable).

any idea what locks and keys were original to this cab

To further the subject on demag for these cabs if its using a MS8-26A chassis. There is a jumper link next to the PTC (J114) thats used in conjunction with the Demag's PTC and I think it gets removed sometimes if a manual demag switch is to be used (which I believe is attached to the points where the link goes). The board labels the jumper link as "J114" and the through holes for each side of the link "x" and "y".

I'm a little late here, but for the love of everything holy, do NOT chop the control panel connectors. I HAVE them and I MAKE replacement CP harnesses with Correct wire colors.
Please do not mangle these uncommon cabinets.

Yes quite uncommon and agreed
I been pointing everyone I sold mine to your way for CP harness's. All the ones we got from a batch in Japan were really uncommon dare I say rare medal redemption variants of the cab.
I did a video walkthrough on one recently since it was the last unit I had and will be getting a loving home.
I think OP's may have come from this same lot of cabs out of Japan originally but not 100% sure, though his isnt a redemption variant. The operator/owner of the cabs we got ours from did some work on them mostly on the CP honestly the work was already in progress when we found them outside that I dont know the full history.

(as a heads up- I have more scans I can send your way when we wrap up the swing stuff!)
