Preventing “Image burn” or 

“Burn-in” on your TV screen

y

y

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.

y

y

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.

y

y

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.
