Re: Problem with picture
Did you hear the familar HUMMM when you turned on the TV? This hum is the internal degauser and if it's not comming on then there is your problem. On most TV brands you can use an external degauser ring o take care of the issue until repaired but, DO NOT do this on a Sony as it will actully damage the CRT.

It is your convergence IC's going out, they cost about 40 $ for both, if you know someone that can solder, i would have them do it, once you see the new parts it is prity easy to find them on the board in your tv, repair shops usually charge 4 to 5 hundred
I hope this helps you but you might wanna look into some other posts too cause it goes farther then the lamps and color wheels. Basically it's a bad product and the consumer should be fixing it. But your problem seems to be the color wheel. Or just a good cleaning. We replaced the lamb in ours and still had a color problem. We're gonna do an exstensive cleaning and dusting of our unit and if it don't work. We're going straight to the manufactor. This is enough with this product! It's costly to repair and still don't have the quality picture it should. It's more then a simple fix and too costly for ppl to just fix and move on. For how old these products are this all should not be happening.
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.
