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 could be a fault in the degausing circuit or do you possibly have speakers that you recently put near the set that aren't magnetically shielded? Or did you possibly move the set to a different location or angle?

Rainbow colors in top corners of tv

Hi

in this issue you have defective crystal color carrier or you have defective Jungle IC. But the best is to diagnose first.

Thanks!

Picture Falling with arch

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

The picture on my 2 yr old Toshiba 42hm66 DLP tv starts flickering and with alot of rainbow looking distortion after an hour of veiwing. I replaced the lamp, but it sill has the probelm. Any idea what...

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.

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.
