Liquid crystal display televisions offer attractive viewing capabilities in vibrant colours. However, the downside to LCD screens is that after a period of time they can experience burn-ins. A burn-in is a shadow of an image that was left for too long on the screen. The image's shadow is faint but can still be seen with a naked eye. Before you consider sending back your LCD TV or shipping it off to be repaired, try reversing the burn-in from home.

Turn off the power to your LCD television and look for the DVI connector. The majority of LCD TVs come with DVI cables. Move your computer or laptop to where the television is and connect the DVI cable to the output video spot on your computer or laptop. Use a DVI-to-VGA adaptor if your computer has a VGA output, so that the graphics card on your PC can communicate with your LCD TV.
Turn on the power of your LCD television, leaving the power of the computer off. Press the "video input" button on your television or the TV's remote and identify the type of connection made between the television and the computer. Power up the computer or laptop and wait for the PC to identify the LCD television as the monitor.
Open the program on your PC for graphics creation and editing, such as Photoshop or Apple's Aperture (for Macs). Create an all-white solid colour image and save it as a picture file (JPEG) on the computer. Select the image document and open it into a full-sized image. Make sure the image fills the entire LCD television screen.
Locate the burn-in image on the LCD screen while the white graphic image is displayed. Adjust the brightness settings to the highest capacity on the LCD screen. Allow the screen to remain bright until the shadow of the burn-in begins to fade and become all white. Set the brightness setting back to its original resolution.
Close the image document and shut down the computer and television. Unplug the DVI connector between the LCD TV and the PC. Allow the television to resume its usual input settings and turn the television on. Look to see if the burn-in is still visible on the LCD screen. If the image persists, try the steps again.
Tips and warnings
- Disable all other activity on your computer, such as automated screen savers or sleep mode, before allowing the white image to appear on the LCD screen.
