Yes, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:

When was the unit repaired last? If it is doing the same thing and is only 5 years old, it sound like a bigger problem than just what was repaired. I own a 56" projection TV and mine is 6 years old and I have yet to have a problem with it...(I shouldn't have said that...) If I were you, I'd call Toshiba and explain the situation and that it has been repaired once already under warranty. Chances are, they'll be able to help you to your satisfaction. I once purchased a JVC stereo receiver from Circuit City and had to take it in to be repaired 5 times and the warranty had expired after my second trip up there, but they were nice enough to repair it - free of charge - the other 3 times. Toshiba seems to be a company that stands behind their product. Good luck! Hope this was helpful...

You need to replace both convergence ICs they are STK392-110 you can get new replacements at the following link and they provide free instalation instructions with pictures so you can do the repair yourself in about a half an hour. You need to replace both ICs same numbers STK392-110. Heres the link.

This is a convergence problem. Try resoldering the pins on the convergence ICs. These are large black ICs attached to a heatsink. They should have about 15 pins and be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs. These should cost about $15-$25 each.
