My 2002 model Sony KP65WV600 appears to be terminally ill. It has served well for almost 7 years without any problem. and has always had a good picture. However, yesterday morning when I turned it on, the picture was distorted, as though looking through a telescpoe, and the colors were all out of allignment on the sides. Horizontal lines along the bottom curve down on each end and along the top they curve up, as though the screen were concave in shape, like a funhouse mirror. I went into the menu and looked at the convergence. The + signs in the very middle were okay, but from there out they got progressively worse, until at the edges the colors were 2-3 inches apart. I tried to adjust but they would not move at all. I unplugged it for several minutes but that did not help. My extended warranty expired a couple of years ago. Any suggestions? Is it worth trying to fix it or time to get a new set? Plasma or LCD? Thanks.
