My old Samsung 20" CRT analog TV in the bedroom has a weird issue. A lage, greenish blob appears on the right half of the screen whenever there is a lot of white on the program. 3 things are sure to cause this-
1. Hockey
2. Brian Griffin
3. The setup menu on the Channel Master 7000 CECB (which has a lot of white)
Is this anything to worry about? It goes away when the white colors do.

Do you have audio speakers or some other source of magnetism near the tv?

No, but I remember doing that when I was a kid. This issue doesn't alter the alignment of the cathode ray and distort the image, it's just the color. It's been going on for several years, even when the tv's location and surroundings have changed.

If the set has been apart the degaussing coil could have come un-hooked. If not, the thermister may have failed.
