Question about Mitsubishi WS-55819 55" Rear Projection Television

Horizontal color distortion on Mitsubishi WS-55819 rear projection HDTV

I've had my Mitsubishi WS-55819 rear projection HDTV since 2002 and in general it's been a great monitor. Just recently however, I've noticed a constant effect of a purplish horizontal band that keeps appearing at the bottom of the screen and moves upward and then repeats. I have several devices attached to the TV, including an Xbox 360, PS3, and DVD. I just recently bought an A/V switcher and the problem is just as pronounced (even more so) when I use these devices. But the effect was present even without the A/V switcher and I've isolated the problem to the TV itself. Any ideas on what this problem might be caused by? I'm dreading the possibility of having to get a new TV (as much as I wouldn't mind it) so any insight on what might be causing the problem would be great!

Mitsubishi Rear Projection TV Model WS-55311

Rear projection TVs are dinosaurs. Sell it if you can get anybody to buy it and get an HDtv they're pretty cheap now not to mention thinner, lighter and better for your eyes. Imagine the space you'll save if you mount it on the wall and the cost of electricity. Not trying to be a jerk but it's time to move into the 21st century. The picture is waaaaay better.

I have a Mitsubishi WS-55819 and the screen is curved and looks 3d. The colors are also blurry. When it warms up it looks better. Any suggestions?

It could just be the solder on the convergence ICs which needs to be reflowed. If that doesnt help then the ICs will need replacement. Your model uses 2 of the STK392-570 ICs. If you need further assistance please let me know.
