Toshiba 43A10 projection television

I have a toshiba 43A10 projection tv, I can no longer line up the convergance as well as before, red and blue still off now matter how much I try to line up, lower portion of screen image cutoff and as tv warms up screen image moves lower, also red and blue moves more out of alinement, almost looks like a 3d comic book that you would have to wear the 3d glasses to see, I'm trying to decide wether to repair it or trash it. Thank you

Picture appears to be 3d

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
•Screen looks 3D
•Colors don't line up
•One or more colors can't be adjusted when using the convergence menu.
•Screen is bowed or warped.
•TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems

Have a model 43A10 toshiba tv, has a purple color at very bottom of screen about inch tall. When i go into the menu, looks like writing is not lined up on the lower options of the menu. and partly up...

you either have a color purity problem or a convergence problem. purity can be effected by electro magnets in power supplys of audio amps and subwoofers too close to the tv

Convergence is the ability of the red green blue to drop on top of each other. can usally be adjusted via remote control. Please claify and repost.
