Initially I would have told you to replace the convergence ICs but after reading your post carefully I think you could have a problem with the convergence box. The lines can only be bent/curved for two reasons. One - the yokes are bad causing an undue strain on the power supply and not being able to correct the problem. Two - the convergence box/board is bad and is not holding the settings causing the curve you see. I cannot tell you which problem you have. You wil have to determine this. I do have a tip at http://www.fixya.com/support/r4273935-replace_digital_convergence_box which may be helpful.
Alot of rear projection t.v.'s have a convergence option in the menu on the t.v. There you can set the try to set the colors back how their supposed to. Mine has a cross in the middle of the screen and you just have to try to get all 3 colors to line up. Unfortunately, the actual lens inside mine has to be aligned so it doesnt work. Just something to try though, hope it helps.
Absolutely! if the consumer control has failed to rectify the problem you need expert help. There are two control boards near the power supply 1 or both are involved and more than 90% of the time both of the boards have to be replace otherwise the problem will occur again in a short time. It is not a DIY project for the unskilled as it has to be tuned correctly when it is installed. Better to leave it to the professional
