Usually when a tv is dropped the phospher screen inside the picture tube will detatch making the rainbow color This cannot be fixed as it requires changing the picture tube. Only other thing is demagnatize it with a demagnitizing coil (used by tv techs) but not likely to fix it since it was dropped. You have a bad picture tube.

sounds like a degaussing (magnetizing) problem.could be that the posistor inside the TV set got loose when the tv fell down. If you have experience soldering electronic components, you should be able to fix it by re-soldering. Otherwise, call a tv tech to do it.

I just had a rainbow of colors on my tv screen...i thought it was a problem with my TV...however the screen went the "sign off" screen (verticle lines-red/blue/green) Then all of a sudden the picture came back and all was back to normal again.
So I say it's nto your TV it is a station problem!

In some cases this is due to the fact the internal degausser stayed on too long and magnetized the CRT causing the rainbow effect. The only way you will know if the set can be repaired without replacing the picture tube itself is to have a technician use an external degausser to see if they can remove the magnetism on the tube and return the set back to normal. If that works then the internal degassing circuit will have to be repaired otherwise it will happen again when you turn it on the next time. If it doesn't work then the tube was damaged by the internal degausser and at that point you will spend over 300 dollars just in parts to repair it.
