A plasma television has a screen of at least 32 inches and contains a mixture of gases in between two pieces of glass. These gases are then turned into a plasma mixture that emits light. Although an LCD-screen TV may look similar to a plasma TV, they use very different technology. One drawback to a plasma-screen TV is that the plasma is very sensitive; if the glass protecting the plasma breaks, you will most likely need to buy a new television. If you are having screen problems other than broken glass, such as a burnt-out screen or pixels, you likely can fix your broken plasma TV screen at home.
Connect your DVD player to the plasma TV. Turn both on.
Place a pixel-correcting DVD in the DVD player. You can purchase a pixel-correcting DVD at most electronics stores or on the Internet (see Resources).
Select the highest screen resolution possible on your television's menu. Keep your TV in this mode for the remainder of the steps.
Access the menu on your pixel-correcting DVD by pressing the "Play" button on your DVD remote. Run pixel correction tests until the pixel-correcting program has accessed your television's problem areas.
Tap your plasma television screen. If you experience no improvement using the pixel-correcting disk, the plasma may have become pressed against the glass and is out of place. Tap gently around the glass until the stuck pixels are released.
If you experience no improvement after following these steps, your television may have external damage.
Do not hit the television with any hard object when trying to release stuck pixels.
