Thanks, the 1st pic somehow got deleted so it should show up now.
You have discoloration?
I think degaussing coils are like $40 at Fry's Electronics. Got a used one on ebay for $20. Not sure if it's a good investment since I only used it for about 15 seconds and I'm not sure if I'll ever need it again.
If you have an electric drill try that first. A lot slower than using a coil but the drill method got rid of like 95% of my discoloration. Unfortunately it couldn't fix the edges. Might have worked if I took off the case/bezel to get the drill closer to the tube edges.
I was able to get it all out by making some adjustments, but now the screen isn't quite centered. The only issue was a little redness in the top right corner.
