CRT dying?

[digitalpencil]

Hi, I'm wondering if anyone can tell me what's happening to my monitors.

For a while now, my Mitsubishi CRT has been shifing the proportion and location of its projected image. As i work in graphics and web, this is obviously very annoying as every time i sit down to work, I have to re-adjust everything, so it sits correctly on my screen. I have also begun to notice color shift. Towards the left hand edge of the image, there is some seperation and blurring and all across the image, you can see slight red shadows dropped behind anything dark. There has also been some periodical bouncing of horizontal bars, (similar to wireless intererance) this comes and goes. This has been fairly annoying, although i've put up with it as I love my monitor and couldn't bare to part with it in preference of a nasty cheap TFT.
Now, however, i'm sat in work and my monitor here is doing the same bouncy/flickery thing with the horizontal bars..
Are all my monitors dying!?! Do CRT have a shelf-life and wear themselves out? or is just that I have bad monitor karma after dropping one a couple of years back?

Any thoughts/advice would be much appreciated, thanks!

Yes, CRTs wear out like everything else. Usually the high-voltage supply will give out long before the tube does.

The horizontal flicker could be caused by the refresh rate. If the monitor is set to 60hz refresh then it will "strobe" when viewed under flourescent lights (which are also 60hz). When this happens, I set the refresh rate to 72hz or higher.

No it's not the refresh rate, i think it's the tube. I just really don't wish to replace, guess i'm going to have to.. apparently soon it's going to make a 'popping' sound and that.. will be that.
*sob*

Replace it with an LCD. No distortion issues there!

Yeh, think I'm going to have to as there's not many CRTs left, but would really rather not. Can't afford a top-end LCD/TFT and the rest are crap.. never as sharp or bright as a good CRT, plus many of the models i've used have had poor color accuracy in comparison.
On the plus side though, i guess it'll be easier on my eyes, you do seem to get blinded by prolonged CRT use.
