I got a TV from a friend who's son had dropped it. The TV turns on and the sound is fine. The picture comes up with about 1/4" wide stripes of red green and blue in a wavy pattern over the picture. You can see the picture OK but have the bands of color over it. When it would normally have white text (say menus) they show up as rainbow colores letters. Is there something simple to fix it or is there some particular damage I should be looking for that would reflect these symtoms. I'm a mechanical engineer who likes to tinker and should be able to track down any components you can describe to me.

I had the same problem with my tv, same make and model. I first continuously turn on and off my tv manually until I could get some kind of picture. This procedure took maybe five minutes. I was able to get a fine picture and sound, as if it was brand new! Other things to keep in mind, try to eliminate dust build up as much as possible.. Hope this helps out...
Chances are is that the actual screen inside is broke, so that the laser cannot display the correct colors in the right spots. First talk to
a TV repair guy, but he will probably just say to
buy a new tv.
