Discoloration on the left side of the CRT, migrates sometime

Post by Roboplodicus »

So I have a Sony 20v80 and it has some discoloration on the left side of the screen. It been there no matter where I place the TV so I'm pretty sure its not a magnetic interference issue. The disoloration also seems to move around the left side of the screen from top to bottom. I have been told it might be a purity issue but I haven't been told how to fix it if it is a purity issue. The screen also has some geometry problems along the edges. Here are a couple pictures I took to hopefully help get a diagnosis. The geometry issues are a little more wonky than the picture makes them look. https://imgur.com/a/lpdxMC2

Edit: I also was told it might be an issue with the degaussing coil. The intensity of the discoloration also changes when I rotate the screen, facing south its the most intense, facing west seems to be the least intense.
