Magnets are one of a crt tv's worst enemy. They gererally take weeks to do this damage. Then it is permanet. This is dependant on how powerful the magnet is. Newer sets automatically de magnitize the set each time the set is turned on and off. I'm sure you could bring the set in and have a service shop use their demag ring. If that don't do it---It's toast. As you probably know a set from '78 must have weak color;maybe it's time to "put it down". (The humain thing to do.)
Can magnets permanently damage CRTs?
I have a 1978 RCA XL-100 TV that I use in my main HT system. It's obviously a CRT and it's solid state. Without naming names, I'll just say that a demonstration of a magnet's effect on the picture tube was performed. Now the picture remains distorted even though the magnet is far away from the TV.
My question is whether the magnet just temporarily affected the CRT's stability or is the CRT ruined?
