Preventing "Image burn" or "Burn-in" on your TV screen
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 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 Avoid displaying a fixed image on the TV screen for a long period of time (2 or more hours for LCD)
to prevent image burn.
