We have a Toshiba tv and when we turned it on the picture has a yellow-green tint to the whole picture. We tried to correct it using the tint and other features but it still stays the same. We have also unplugged the tv from the wall hoping it would reset itself. Any suggestions?
I recently had a focus block replaced on my Sony KP-57HW40.After getting it back the picture had a green tint to it. I called my repair guy and he said it would adjust itself and it did for about a month and a half. Now I turn it on and a good picture lasts for 5-45 minutes and then it goes to the green tint. I called the repairman back and he said me problem was unrelated to the focus block replacement.PLEASE HELP ME.

Re: picture has a green shade
This problem is called the gauss' effect. Its caused by the prescence of magnetic materials near the tv. If anything please move them away from the tv. If your tv has the degauss option just degauss it when it happens. IF none of this works then its probably a problem with your convergence IC. Please let us know so that we can assist you further.

TV has 3 CRTs, red, blue, green. Its possible that you have a bad blue or green crt. If that were the case the red would be prevalent and the pic would be reddish. The tv has a picture "level" adjustment that if done correctly could get it looking correct. Its probably best to have a tech. do it since you can make it worse if you do not know what you are doing, also there are high voltages present. Good luck
On/off switch is a normally-open,momentary hold binary switcvh- is burned out or dust/contaminants in the switch. First try spray-air keyboard cleaner on and around the switch. Otherwise, replace )professional svc.)

Sounds like your red picture tube is not emitting enough brightness to balance the colors. A temporary solution could be to slightly increase the screen voltage of the red CRT to give a good black and white picture when the color control is turned all the way down. If the set has not been serviced in the last 5 years or so, and you're not ready for a new HDTV set, it may be worthwhile to get a technican to look at it and clean the dust off the lenses and mirror and evaluate whether a picture tube rejuvination might work along with the gray scale tracking adjustments.
