Screen burn is an image ghosting effect that is caused by keeping a static image on the plasma screen for an extended period of time. An example would be the logo of a TV station or the menu of a DVD. This issue is unique to plasma TVs. The resulting screen burn is seen as a residual ghosting of the static image once the original image has been removed. The easiest way to remedy screen burn is to utilize a combination of Samsungs built in screen burn protection utilities such as All White or Signal Pattern and allow some time for the ghost image to dissipate. It should be noted that as your plasma ages, it will become more difficult to remove residual screen burn images. Another malady common to plasma TVs are stuck pixels. This is where a red, green or blue pixel will fail to reset and remains conspicuously on the screen in the midst of the new images being displayed.

To utilize this program, you will need to run it off of a laptop that is hooked up to your plasma television.
