Preventing “Image burn” or “Burn-in” on your TV screen

If a fixed image displays on the TV screen for a long period of time, it will be imprinted and become 
a permanent disfigurement on the screen. This is “image burn” or “burn-in” and not covered by the 
warranty.

If the aspect ratio of the TV is set to 4:3 for a long period of time, image burn may occur on the 
letterboxed area of the screen.

Avoid displaying a fixed image on the TV screen for a long period of time (2 or more hours for LCD,  
1 or more hours for the Plasma TV) to prevent image burn.
