Hello
For every standard televisions, there will have a degaussing posistor, to demagnatise the picture tube, each time it is switched ON. If thie degaussing posistor has damaged, there will be no degaussing action and color patches on screen will be the relsult.
Moreover, check whether there is any external speaker boxes have placed near the Tv. The magnetic effect from the magent of the speaker can also cause this.
Posistors sre of severel types, and the pictures of some of them are given here.

SOURCE: Toshiba TV colours wrong pink sky, blue clouds and green people??

Inside your TV there is like a loop of insulated wirings the loop around the screen. This is to demagnetized the tube. There is a varistor which looks like a thick coin with two leads on it, or sometimes it looks like a flat ceramic capacitor that control this loop of wire. When you first turn on your TV current goes through the loop of wires to demagnetize the TV then the varistor shuts off. Sometimes this varistor fails, causing smeard colors. You can also demagnetize the screen without opening the TV. Using a hand held demagnetizer. It can be purchased at some electronic parts store.

Laptop LCD/Display Problem, Green and Pink Tints???


Their are a couple things that could be causing this, My first thought is that the screen its self is damage. A LCD screen is composed of millions of tiny pixels so when some fails others will still work.
That other thought is that the GPU or video device on the laptop could be failing and creating video problems. Have you tried closing the laptop and opening it agian, this would help rule out a bad cable connection.

KP-61HS30 Sony TV turn pink and green text is bowed


Hi,

Check out CONVERGENCE GALLERY . If you see your symptoms you have a problem in your convergence amplifier circuits. Typical Sony Convergence repair requires disassembly for replacement of 2 ICs, sometimes a fuse or 2, then TV is like new.

It is much more complicated than changing batteries on your remote. Many consumers try unsuccessfully to do a convergence repair. I recommend finding someone competent to do it for a reasonable price. Typical repair shop charges may be from $400 to $650.

If you are in the Calgary area, call me. More reasonable rates.

Sudden pink hue to faces


It sounds like you lost your green, try turning down your color all the way and see if the screen is B&W, if it is then you have a problem in the ry-by-gy processor. If tthe screen is not B&W then I would suggest the Green video driver on the green CRT is bad or in that area>let me know!

PINK/GREEN SHADOWS, LINES


Here is what I was able to find out about your problem from sony: This issue is usually caused by some type of nearby magnetic interference, such as unshielded stereo speakers placed too close to the TV. These spots can be small or large and will normally be red, green or blue, but sometimes appear purple or pink. They normally occur on the sides or corners of the screen, but can also appear in the middle. To resolve this issue, move any stereo speakers or other electronic devices away from the TV; a minimum of 2-3 feet is recommended. If the situation is not remedied immediately, unplug the power cord of the TV from the electrical outlet for 20-30 minutes; repeat this process one more time if the issue is not resolved the first time. If the issue is still unresolved, service may be required. The Sony® eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer in your area. Hope this is helpful:)
