CRT Phosphor maintenance

[old_tv_nut]

I have not heard of problems with CRT (especially the phosphors) that could be helped by running them occasionally. On the other hand, TV camera tubes were generally said to need running occasionally to prevent problems with low level gas buildup. I don't know if a similar problem could occur in a CRT, but I suspect it would be very minor, since the camera tubes that were most susceptible had very small cathodes.

Maybe some of the folks who have brought old sets back to life can speak about the possible deterioration of cathodes and how frequent use might help or not.

Regarding CRT phosphors, they are always in "wear-out mode" when in use, hence the problem of burn-in of stationary images. Obviously there is no burn in occurring when they are not in use.
