Preventing "Image Burn" Or "Burn-In" On Your Tv Screen - LG 55LB5800 Owner's Manual

Dot Defect
y
The Plasma or LCD panel is a high technology
product with resolution of two million to six million
pixels. In a very few cases, you could see fine dots
on the screen while you're viewing the TV. Those
dots are deactivated pixels and do not affect the
performance and reliability of the TV.
Generated Sound
y
Cracking noise A cracking noise that occurs when
watching or turning off the TV is generated by plastic
thermal contraction due to temperature and humidity.
This noise is common for products where thermal
deformation is required.
Electrical circuit humming/panel buzzing A low level
noise is generated from a high-speed switching
circuit, which supplies a large amount of current
to operate a product. It varies depending upon the
product. This generated sound does not affect the
performance and reliability of the product.
Take care not to touch the ventilation openings.
y
When watching the TV for a long period, the
ventilation openings may become hot. This does
not affect the performance of the product or cause
defects in the product.
Do not install this product on a wall if it could be
y
exposed to oil or oil mist. This may damage the
product and cause it to fall.
If the TV feels cold to the touch, there may be a small
y
"flicker" when it is turned on. This is normal, there
is nothing wrong with TV. Some minute dot defects
may be visible on the screen, appearing as tiny red,
green, or blue spots. However, they have no adverse
effect on the TV's performance. Avoid touching the
LCD screen or holding your finger(s) against it for
long periods of time. Doing so may produce some
temporary distortion effects on the screen.
Preventing "Image burn" or "Burn-in" on
your TV screen
If a fixed image displays on the TV screen for a long
y
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
y
of time, image burn may occur on the letterboxed area
of the screen.
Avoid displaying a fixed image on the TV screen for a
y
long period of time (2 or more hours for LCD, 1 or more
hours for the Plasma TV) to prevent image burn.
