Hello,I have an 12 yr old Mitsubishi 27" regular TV in the bedroom that I was watching maybe a year ago and all of a sudden the screen turned off color and there was a circular distortion taking up most of the screen, like looking through a 'fish eye' lens or through the bottom of a Coke bottle. I can turn the color and tint down and pretty much watch it in B/W and the circular doohickey is not a major issue.
However, last night, my big 36" Toshiba tubed Gateway computer monitor suddenly turned a nice pretty shade of light blue. The picture quality and TV function (All In Wonder Rage Pro 128) all seem to be perfectly in focus with no distortions that I can see. Since this has individual R/G/B adjustments, I really can't do black and white, but I was just wondering if this is the same problem, more or less?
Some have said a color gun could have gone out, others thought just a component or something has burned out. The Mitsu TV issue seems to be a focus thing to a degree, but with this monitor, it is like one of the color thingys went south. I did not hear any noise and I was just looking at a picture of a speaker when it suddenly happened.
I have tried reseating and cleaning the monitor cable at both ends, I have tried the degauss function and I have rebooted and even let it sit for six hours or so, off. One AA chatter said it could be a thermal/cold solder joint, but this monitor is on for the better part of most every day, so she has a lot of hours on her over the 6+ years I have had her.
Do these sound like catastrophic problems, or something that can be fixed with a little cash by a TV/Computer repair guy? The monitor is 185# and quite bulky, so it is not easy for me to move it around without the help of somebody else. What should I say that I think is the problem if I call some shops?
Sorry for all the questions, but I could have lived with the B.R. TV being on the fritz, but this monitor is the L.R. TV and its tough to get a fun picture to watch, obviously.
Thanks for any help that you can provide.

Chris, I'm not sure about the Mitsubishi but do you have another source (computer PC, laptop, etc) that you can hook up to the 36" Gateway tube? You might try to isolate the problem to either the 36" tube or the PC, if you can. If you're seeing all blue it seems that green and/or red may have gone out. Does the 36" tube have a HD15 "VGA" connector or just R G B? In addition to R G B, is there a separate composite sync connector or separate vertical and horizontal sync connectors. If its just R G B then I would guess that it's 'sync on green' and if this is the case, green is not out or your screen image wouldn't be stable. In any case, I'm rambling. First things first. Try isolating the problem to the 36" tube or the PC if you haven't already done so.
Also check around your monitors. Its easyly a possibility that all of a sudden you have purchaced a new appliance and your monitors which are CRT and being doused with a heavy dose of magnetic radiation. This can cause tubes to completely go out.
right after I wrote this post, I was reading on Gateway Destination website and another fellow with the same monitor had his in storage for a while and when he fired her up for the first time, he got a pinkish tint, similar to my blue. That monitor has less than 200 hours on it vs. thousands and thousands for mine.Since I can't display red as red, but only black, I'm assumming that there is a cold/broken solder joint on the 'red gun'. Blues and greens display as good as one can expect without any red being thrown into the mix.
I don't have another monitor and I was going to haul the computer down to BestBuy or CompUSA just to rule out the AIW video card, but after reading his post, I'm sure it's the monitor. It just uses a regular computer cable, so no individual R/G/B hook ups. It does .93 dot pitch at 75Hz refresh and 800x600 max.
Anyhow, I'm living with it for now.
Take care, Chris
