Having analyzed the work of some plasma TVs, it’s high time now to draw attention to one of the most common and frequent problem - that is burning out pixels on the plasma screen. For a start, let’s clarify some terms:

- Afterimage: after long-term administration of high contrasts of the image (white color) there stay the charge of pixels for some time on plasma TV. But the main is that this effect is temporary and it can always be “washed off” with another dynamic image or by turning the TV off at night.

- Burning out pixels on the screen. It’s known, that heating of phosphorus leads to a temporary blinking as a consequence of change of the properties of the phosphorus. We show this on the example. For lighting up of every pixel on plasma, the gas must be converted into a noble gas, which in its turn increases the amount of phosphoric particles. During every magnetization, pixels lose their brightness. Usually, plasma TV loses half of their brightness after 60,000 hours of use (this is 21 year, if you watch TV 8 hours a day). Imagine a plasma panel, where a long period of time (let us say 6 months) is shown one and the same image.

Pixels in white color in a greater degree increase the amount of phosphorus that leads to a greater fall of brightness than on the black color. After 6 months of use, there can appeared such phrase “Screen burn” (“Burning out pixels on the screen”) as some pixels can be more dim than another that demonstrates burning out pixels. It’s just a simple example; in life burning out pixels on the screen is the cause of appearance of logotypes of channels.

Frankly speaking, the problem of burning out pixels on plasma TV is getting less important, as the producers develop new technology to solve this problem. The producers test thoroughly their product at factories before sending them to the consumer, use new technology that the movement of pixels wasn’t noticeable and it’s enough for preventing of burning out pixels on screens. The producers of the most new models, particularly, plasma TVs Panasonic and plasma 3d TVs Pioneer offer protective screen for the channels with the proportion of 4:3.

All this points to the fact that it’s better to prevent magnetization during the first 200 hours of work of plasma 3d HD TV, while the emission of phosphorus is unstable, otherwise, plasma is in a big danger. The most correct method of preventing of burning out pixels is selection to the mode “cinema”, decreasing of brightness and contrast and using plasma HD TV in normal mode, trying not to select another image for 30 minutes. Also try to use the zoom mode, filling plasma screen to the size of 16:9 when viewing channels 4:3 or 2,85:1 for DVD the first 100-200 hours of use.

But after all, if you want to hasten a process, here is a step-by-step description of quick method:

1. Make accurate adjustment of brightness and contrast of you plasma TV. Without the line of marking, set it up till the level of slightly less than half of maximum possible.
2. Display a paper-white image on the whole area of plasma 3D TV. Make sure that you also don’t push the pause button.
3. Gradually increase the periods of turning on and off the device (for example, when it works 2 hours, than turn it off for 1 hour, 4 hours of work – turn it off on 2 hours, 5 hours work – turn it off for 2 hours etc.) In that case, phosphoric particles will be able to be stabilized in time, and you will be able to prevent the problem.
4. The work of TV from 50 to 100 hours will lead to decreasing of emission of phosphoric particles that leads to minimizing of the risk of burning out pixels on plasma.

This method works owing to the fact that phosphoric particles are burning out regularly, showing one and the same transmission activity on the whole plasma TV.

You can also use Pixel Protector (Protection of image’s elements). This is a special DVD disk, which helps to prevent burning out pixels on plasma.
