ok, you are talking about lines in the picture, it started where it would clear up after a few minutes but now it will slowly take longer?

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.
Thanks for using FixYa and for the great rating.
