Plasma TV Video Troubleshooting
Your plasma TV will shut itself off if it has blocked vents. (Plasma panel image by Nikolay Okhitin from

The leading manufacturer of plasma displays, Fujitsu, along with inventors of the plasma television, Donald Blitzer, Gene Slottow and Robert Wilson of the University of Illinois, received a 2002 Emmy award for technological achievement. They combined excellent high resolution with a display thin enough to hang on the wall. Watching your plasma TV can make you feel you are in a movie-theatre as you view strong colours and deep black levels. You can watch your plasma TV from any angle and still see the same picture. Troubleshooting and caring for your plasma TV properly allows you to enjoy your TV for 10 years or more.

    Erase a temporary burn-in by playing a monotone, grey static image. Run this program after the first 100 hours of viewing as a preventive measure. Your plasma TV may have installed an anti-burn setting which eliminates ghosting by recalibrating the pixel intensity levels evenly.

  2. 2

    Move your plasma television away from lights or any electrical appliances if you notice interference on the display.

  3. 3

    Change the picture mode of your plasma TV to a lower one to help reduce a buzzing noise. What you hear comes from electrical charges making images on your plasma TV screen. Lowering the picture mode means the image will be less bright from less electrical charges used, resulting in a lower buzzing noise. Relocate your plasma TV away from hard wall surfaces if you hear buzzing sounds from your TV. The wall reflects the buzzing noise your plasma TV normally makes.

  4. 4

    Remove all objects you find which may be blocking the vents of your plasma TV if the TV power turns off suddenly. Anything blocking the vents makes your plasma TV overheat, and your TV will turn itself off automatically to avoid internal damage.

Tips and warnings

  • Prevent burn-in on your plasma television display by turning off your television when you have finished watching it. Do not leave still images on your plasma television for over an hour. For example, you do not want video game still pictures or computer images to remain on your plasma television display for a period of time.
  • Use the power management settings and automatic screensaver when displaying video games, which have still images. These features protect your plasma television, keeping it from burn-in.
  • Watch most of your television programs in full screen mode, which is the same as widescreen. This prevents black bars from displaying on your television screen for long periods of time, which can cause burn-in. The crucial time period to avoid displaying black bars on your television screen occurs during the first 200 hours of use.
  • Before purchasing a plasma TV, check the manufacturer's warranty to read its policy on dead pixels. Although uncommon, dead pixels may appear on the plasma screen. They look like a white area or an area of one bright colour or a black spot. Your warranty may not cover dead pixels since some manufacturers do not see this as a defect, although manufacturers may be changing their pixel policies.
