How to Fix Image Persistence on LCD TVs
LCD panels separate the colouring of pixels from their lighting, preventing permanent burn-in. (full hd lcd tv image by mattmatt73 from

Image persistence or "screen burn-in" has troubled television owners for generations. Thankfully, the design of LCD TVs prevents the permanent destruction of the screen possible with older CRT TVs. On those sets, ghostly images would remain due to uneven wear in the lighting elements. Because LCDs backlight their image with a fluorescent bulb, this does not occur. Instead, image persistence on an LCD happens when pixels become stuck on a certain colour. Several methods of repair for this problem offer a simple fix.

Skill level:


  1. 1

    Use your LCD TV as normal. In many cases, stuck pixels will simply work themselves out over time as they attempt to shift between colours with no intervention required.

  2. 2

    Display bright images on the screen. Try to get the stuck area to show white. White images force the TV to light all its primary colour pixels, which in turn can work out the stuck ones.

  3. 3

    Watch fast-moving images on the LCD. If your normal television viewing contains primarily slow action, it will take longer for the stuck area to work itself out. Video games or action movies offer easy ways to generate rapidly changing images.

  4. 4

    Attach your LCD TV to a computer. Create an image on your computer of pure white. You can do this in any image editing software or simply by displaying the white background of a blank web page or text document. Leave this white field on screen for an extended period of time to attempt to reset the stuck pixels.

  5. 5

    Create another image on your computer of pure black. Cycle through this and the white image manually or using any applicable software such as a slide show program. This may offer the stuck pixels a better workout than regular television use.

  6. 6

    Use specialised software on your computer to repair the stuck image. Several programs exist which make use of the same basic principles to fix your screen. They display a rapidly shifting pattern of lights and colours over the stuck area, working it out far faster than possible with natural use.

Tips and warnings

  • Simply turning off your TV and waiting for the image persistence to fade will not work. Fixing the problem requires exercising the stuck pixels through use.
  • While displaying a white image on your computer to fix persistence, make sure to have the image showing full screen, so no other static images will cause new persistence.
