If you leave your television screen on a single image for an extended period of time, it may result in the image being "burnt" into your LCD screen. Screen burning occurs when the stagnant image becomes imprinted on the liquid crystals of the LCD screen. To correct the problem, you will need to flash a series of alternating black and white colours to remove the traces of colour from the screen.

Turn on your computer and create a folder labelled "Screen Burn" on your desktop.
Open the "Paint" application on your computer by clicking on the "Start" menu in the bottom-left corner of the desktop screen and clicking on the "All Programs" option. Scroll over the "Accessories" option with your mouse and click on "Paint" from the slide-out menu.
Save the blank, white canvas as a JPEG image file into your "Screen Burn" folder by clicking on the "File" tab across the top and selecting the "Save As" option from the slide-down menu. Set your destination for the file within the "Screen Burn" folder and click the "OK" button to save.
Create a black canvas in the "Paint" application by selecting the "Fill" icon in the left toolbar and choosing black from the colour palette. Left-click one time on the canvas to make the entire canvas black. Save the black canvas as a JPEG image file into the "Screen Burn" folder as well.
Connect your computer to your LCD television set using the appropriate video connection cable. If your LCD television has a VGA port, you can use the same VGA cable that you use to connect your PC to a monitor. It does not matter what type of video connection cable you use as long as there are compatible ports on both the TV and computer.
Change the playback display settings on your computer so that the LCD television syncs up with what the computer is displaying. Since each computer uses a different operating system, consult your computer manual to find out how to display it on an external LCD monitor. For Windows 7, go to the "Control Panel" option in the "Start" menu and click on the "Appearance and Personalization" icon. Select "Change Display Settings" and choose the "Display" option. Click on the "Detect" monitors button and wait for your computer to detect the external LCD television. In the drop-down box next to the "Detect" button, choose your detected LCD television as the secondary display. Press the "Apply" button to save and confirm the changes.
Right-click on the desktop screen on your computer and select the "Properties" option from the drop-down menu. Navigate to the "Screen saver" tab across the top of the window.
Choose the option to import a photo slide show as the screensaver. Click on the "folder" icon and select the "Screen Burn" folder where your black and white screen images are saved.
Wait for your computer to idle out, which will activate the screensaver mode. Allow the screensaver to play for at least 30 minutes, alternating between the black and white images. If the screen burn has decreased in intensity, but is still visible, run the screensaver for another 30 minutes or until the screen burn is completely fixed.
