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 on the product.
This generated sound does not affect the
performance and reliability of the product.
Take care not to touch the ventilation
y
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.
IMPORTANT SAFETY INSTRUCTIONS
Preventing "Image burn" or "Burn-in" on your
TV screen
If a fixed image displays on the TV screen
y
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
y
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
y
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.
