It knocked the inside color wheel or tubes out of alignment. Check menus for "convergence" and try to readjust. You may need to call in a pro to fix it, but search your model number on trhe net and see if you can find the service manual.

The tv problems is call a convergence picture problems,it is just starting to developing.This problems when it is fully developing into a convergence picture problems to the tv eventually.Tv will develope into a colors lines R,G,B mis alignments,have a colors shadow pictures or into a picture 3D look alike.Eventually the tv convergence board will dies,have to have it parts replaced like 2 STK convergence ICS and some or all of it resistors too.This problems the tvs shops will cost u like $300-350 for parts and lobors.

Bullseye rainbow of colors


This is either a purity fault which is caused by magnetism affecting the screen. You would need to call a service engineer to remedy this as a special tool is required called a de-gauss coil. However there is also the posssibility that it could also be a fault with the shadowmask which is caused by the CRT itself, if this is the case then the CRT will need replaced & this would probably not be economical.

I have a rainbow of color about the screen. The TV fell out of the stand and now the color pattern is messed up. It fell face down.


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.

your convergence IC;s are out, they cost about $40, if you know how to solder, you can do it your self, if not , I would try to find somone that can, service centers charge about 4 or 5 hundred, after you get the new ones, there easy to find on the board in the back of the tv

Sony Trinitron Color Rainbow


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.

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.
