Burn-In
bkenobi:
My mp3 player has burn in where the song's progress bar is located. LCD's can burn in too...

In practice, doing so is impossible: you'll just end up with an even more objectionable pattern since you won't get it lined up perfectly, and it would take forever anyway. Either live with it, replace the monitor, or swap tubes.

Absolute rubbish...
If you are planning to throw it out, then I would say to try the reverse image for the sake of experimenting.

First he can't find the "New" icon and now he's lost his quote-fu. Just look at what KLOV (or perhaps age) has done to Frizz. :'(

If you want to try the reverse burn trick, here's the only way I can think of to do it that could even remotely possibly yield useful results. You'll need the original source for exactly what was on the screen, and DO NOT MESS WITH THE CONTROLS. Grab a video inverter and hook it inline. Run the monitor for about as long as it took to burn things in. You can attempt to accelerate the process some by cranking up the contrast, but that will make it bloom which would ruin the "reverse" effect. If you're really, really lucky, you'll end up with a substantially dimmer tube that has little in the way of burn.
Note it will still be dim. Effectively, you're burning the whole thing in equally. It will also take a LONG time. It still probably won't work very well since the spot sizes will be different due to the higher average brightness and component aging. You'll probably just end up accentuating the edges of the burn artifacts. This might work a little better on a Plasma since it has discrete pixels.
