Preventing "Image Burn" Or "Burn-In" On Your Tv Screen - LG 43LF540T Manual

• Do not use high voltage electrical equipment
near the TV, (e.g., a bug zapper.)
This may result in product malfunction.
• Dot Defect
The 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
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.
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
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 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 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.
