I recently returned from holiday, and found that my TV had suddenly decided to show pictures in Pink and Green!?
I have a scout through some other issues on this page, and noticed that magnets and amplifiers could possibly be the problem. I have since checked that these are not in the vicinity, and am still no the wiser ?
Hi there your problem is a component called a degause thermistor its a part the demagnetizes the crt. They are very common for just dying but it will need to go to a repair shop to fix it myself i charge about £30 for this repair but i dont know what others charge All the best Bob

Picture goes to high green with retrace lines that shows picture tube is defective and requires replacement. Usually in above symptom, TV goes to standby mode and standby light blinks when green raster problem occurred. New TV is better option because picture tube of KV-34XBR960 would not be available any more. Thanks.
hello.... do you have any speakers near your television? what color is the circle your talking about? Do the green,pink colors are scattered all over the screen and specially on the corners? If you have or had speakers near your tv? then do this try to get a magnet.a magnet on a speaker would do.what you have to do is to place the magnet near the screen of the tv approx. above the green,pink color (turn it on first).you will notice the that the color will react with the magnet try to pull it on the side you will notice that the green,pink color is moving on the same direction do it until its gone.NOTE make sure youll not scratch the screen ok.email me what happened. email@example.com GOODLUCK
May be that the colour Amp is at fault or the tube is busy failing. Commonly it would be the colour Amp (Dry joints or faulty drivers). The Green is dead. I have had cases where power surge can magnetise the tube to such an extend that the whole picture will show one colour. In your case I doubt it very much. Good Luck,JUS004
Are you getting Green or purple or pink patches all over the screen? This could be a problem of Degaussing. Have you placed any Magnetic source near the TV recently? Some Tape recorder or walkie talkie or a Speaker, etc? The Magnetic field created by any of the above sources can cause coloured patches over a colour TV screen. It also happens if you shift the TV from one location to another.
The third possibility is that the Picture Tube's Red Output stage gone faulty. Unless you are a trained Solid state Electronics Technician, there is nothing you can do. Better go for a trade in.
I would suggest check the the secondary side of the power supply for around 130VDC if that voltage is found to be lower than 120VDC I would suggest to replace CP80 with a 100 mfd@250 vdc. Part # 218374 Check Globalsemi.com for these parts.
The solder joints on the degaussing thermistor have cracked or the thermistor itself has opened, and the CRT is heavily gaussed. You can degauss (demagnetize) the picture tube and the colors should return to normal, but the thermister should be resoldered or replaced.
