How does a plasma TV screen work?
The way plasma displays work is similar to how a florescent light bulb works, gas is used to excited phosphors which produce visible light. In plasma displays a voltage is given to the gas within the cells and the gas becomes ionized, creating plasma.
How are plasma screens made?
Plasma screens are made of two sheets of glass with two gases stored between the sheets. The gases are xenon and neon and they fill thousands of tiny chambers, or spaces. Behind each space are a series of red, blue and green phosphors that give off light when struck by radiation.
What is the picture on a plasma display made of?
Each pixel in a plasma display is made up of three cells comprising the primary colors of visible light. Varying the voltage of the signals to the cells thus allows different perceived colors.
Are plasma TVs worth fixing?
Plasma Screen is not repairable. In my humble opinion a Plasma Screen TV is not worth the effort in finding parts to repair. They are heavy, power hungry and prone to picture burn in a way that the new extremely light weight LCDs are not. Write it off and look for a LCD replacement.
Do plasma TVs give off alot of heat?

Is plasma TV dangerous for health?
While plasma TVs do not produce x-rays, they do emit very small amounts of UV radiation. UV radiation increases a person’s risk for skin cancer. Plasma TVs emit such miniscule levels of UV radiation that it probably won’t harm you, but you can use UV-blocking sheets if you are concerned.
Do plasma TVs overheat?
Overheating. Plasma televisions produce a considerable amount of heat when in use. Although most include a built in fan or other form of cooling system to prevent overheating, excessive strain placed on plasma’s cooling system can significantly shorten its lifespan and may damage electrical components within the unit.
How much electricity does a plasma TV use?
Electricity Use By Type A 42-inch model often sucks up 200 to 500 watts, and a 60-plus-inch plasma screen can consume 500 to 600 watts, depending on the model and programming, according to the Environmental Protection Agency.
