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.
TRY USING A DEGAUSSING COIL TO FIX IT
The shadow mask in the picture tube has shifted from being dropped. The only way to fix the set is to replace the picture tube, which would cost more than buying a new set.

Here's a picture of what the screen looks like
Well, with everything I've seen about the TV basically being best off thrown away due to repair cost - as a last resort, I decided to simulate the TV being dropped the other direction to see what it would do. I banged on the side and watched the direction the distortions shifted and then hit it at different locations until I determined the direction it needed to shift. After a few firm hits, there was a light click sound and the picture was perfect. This may have been a fluke and may never work any other time but if it's going to be thrown away anyway it's worth a try. I figured I might get it a little better to use as a garage tv but it fixed perfect with no distortion, rainbow, or anything - Perfect picture. Probably just lucky this time.
I dropped my TV screen hit the floor, it works, but is it safe to use? I heard it could be a fire hazzard?

when plugging in some chords to the back of set, the sharp tv fell forward on its screen down about 3 feet onto carpet. the sound and picture are there but a rainbow of color (similar to other ?? pictures, not as thin, broader rainbow stripes) prevails on the picture.
