My husband dropped our Sony Tv and now there is a rainbow vertical stripe on the screen but the picture behind it is fine. Is this fixable or not worth it for the cost??

Re: 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.

My screen turned into all colors after i dropped the tv


If the colours on the screen are like a "rainbow" then I'm afraid your tube is damaged - probable cause is the shadow mask in the tube itself has slipped. Dropping a CRT TV set is not good and all sorts of things can happen to the tube.

Carrying monster TV's like this you should always have TWO people carrying it - put it down to experience - you have learned the hard way!

Looks like you'll be buying a new TV!

I dropped my 27in phillps magnavox

if this is a distorted kind of rainbow aura affecting the colour, you need to de-gauss the screen - a good tv repair man will have the mains powered magnet to fix this - and shouldn't charge alot.

Sony Wega 29" TV screen cracked

Definitely this is due to thunder. Apart from rarely following type of problem occurs through vertical section also. Before you got the screen cracked past month or past week days you observe any rainbow color screen or single horizontal line in the center of the screen means there is a chances to crack. Unless otherwise any physical damage by any other person or the above mentions symptom there is no chances to crack the tv screen. Since it is not designed like that moreover this is SONY

Line across top of screen

If the picture is ok otherwise then only thing that probably needs to be done is a vertical height adjustment. That is if the lines never changes position from cold to hot.

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.

Sony FD Trinitron WEGA KV-36HS500 36" TV - Bowed Picture

it sounds like a convergence adjustment problem. If you hava book on the tv still read it, and it will tell you what to do, other wise, look for a convergence button on the front of your tv, and take the remote and push menu to bring up setup, and go convergence adjustment click it and hit the conv. button on the front of the screen. there should be to lines going vertical and horizontal, these are the limes you adjust with your remote, you have to adjust the red and blue, the tv should blink to let you know which color you are on. when you have them lined up right the line will be perfectly white. hope this helps

Rainbow on the tv

The only time I have seen that symptom is when the shadow mask of the picture tube gets loose,What that means is you might be looking at a bad crt,color splashes could be a purity problem but rainbow lines are not.Sometimes that happens by itself or by being drop.Good luck
