A plasma screen uses tiny cells of low pressure gas to generate an image. Once the cell is filled with the gas during manufacture, there is no way to repair the cell. If the gas composition is disturbed by damage to the screen, the only repair is a screen replacement.

Why is TV plasma the most common phase of matter in the universe?
Television plasma is not the most common phase of matter in the universe. It is merely a superior means of showing high definition television.
How many watts does a plasma tv used when it is turned off?
It obviously varies from TV to TV, but between 0.3 and 10 watts, with newer ones taking less.
A 42 Vizio Plasma TV makes a crackling noise when set is on can you tell me why?
If tv is new call engineer this is not normal.
Difference between lcd monitor and lcd tv?
A. The next answer has nothing to do with this question. I will return when I have a more complete answer, but to begin with an LCD TV has a tuner in it while an LCD Monitor does not. LCD TVs are designed for use in higher light situations such as a bright room, LCD monitors are designed for use in controlled light environments such as offices. There are other differences, but you need to compare them directly which is hard since most Web sites don't allow cross category comparison. The best way to compare is to go to a big box retailer and compare them. But of course TVs and Monitors are in different departments. If you ask nicely maybe they'll let you set them up side by side. A. Outward appearances are definitely deceiving when it comes to LCD and Plasma televisions. Although both types of televisions are flat and thin, they employ different technology in an attempt to deliver similar results. Plasma TV Overview Plasma television technology is based loosely on the fluorescent light bulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel (picture element). Although Plasma television technology eliminate the need for the bulky picture tube and electron beam scanning of traditional televisions, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images. LCD TV Overview LCD televisions, on the other hand, use a different technology (see also question #1 for this same explanation). Basically, LCD panels are made of two layers of transparent material, which are polarized, and are "glued" together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Current is then passed through individual crystals, which allow the crystals to pass or block light to create images. LCD crystals do not produce their own light, so an external light source, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer. Unlike standard CRT and Plasma televisions, since there are no phosphors that light up, less power is need for operation and the light source in an LCD television generates less heat than a Plasma or traditional television. Also, because of the nature of LCD technology, there is no radiation emitted from the screen itself. Plasma vs LCD The ADVANTAGES of Plasma over LCD are: 1. Larger screen size availability. 2. Better contrast ratio and ability to render deeper blacks. 3. Better color accuracy and saturation. 4. Better motion tracking (little or no motion lag in fast moving images). The DISADVANTAGES of Plasma vs LCD include: 1. Plasma TVs are more susceptible to burn-in of static images. 2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images. 3. Does not perform as well at higher altitudes. 4. Shorter display life span (about 30,000 hours or 8 hrs of viewing a day for 9 years) than LCD. However, screen life span is improving to as high as 60,000 hours. due to technology improvements. LCD television ADVANTAGES over Plasma include: 1. No burn-in of static images. 2. Cooler running temperature. 3. No high altitude use issues. 4. Increased image brightness over Plasma. 5. Longer display life (about 60,000 hours - at which time all you may need to do is replace the light source, not the entire set). This can vary according other environmental and use factors. 6. Lighter weight (when comparing same screen sizes) than Plasma counterparts. DISADVANTAGES of LCD vs Plasma televisions include: 1. Lower contrast ratio, not as good rendering deep blacks. 2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts) - However, this is improving. 3. Not as common in large screen sizes above 42-inches as Plasma. However, the number is growing fast, with some LCD sets having a screen size as large as 65-inches now available to the general public. 4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you. 5. LCD televisions are typically more expensive than equivalent-sized Plasma televisions (although this is changing), especially when comparing EDTV Plasmas to HDTV-LCD Televisions.
Does a plasma TV have a color gun that displays the picture?
By screen name Chris -- Plasma TVs use thousands of sealed, low pressure glass chambers filled with a mixture of neon and xenon. Behind these chambers are colored phosphors, one red, one blue, and one green for each chamber. When energized, these chambers of "plasma" emit invisible UV light. The UV light strikes the red, green and blue phosphors on the back glass of the display making them produce visible light By clinnin Plasma TV's do not have a color gun, only tube TV's do.
Do plasma TVs need degaussing?
No!
Do you need a plasma tv for HD pvr?
No, but you need a T.V that has a component input.
What is the differene between plasma and HDTV?
Plasma and HDTV are not comparable since Plasma is a type of screen and HDTV is a type of video. Meaning that a Plasma TV can run HDTV on it, so there is no need to compare the two.
I'm interested in buying a plasma tv..but I need to make sure this is what they call a HDTV..Is it?

When buying a tv stand for a plasma tv do you need to know the plasma screen size?
Most TV stands are suitable for plasma TVs of any size, and therefore the screen size is not important. Of course, if the screen is very heavy, then a solid stand is needed.
What is the difference between plasma the state of matter and plasma tv?
There is no difference the only thing is plasma is in a TV in plasma screen TV and plasma is outside of the TV in the state or matter.
Why you need ahd cnverter box if you have anew plasma tv?
