Dot Defect
y 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 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
y 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.
Do not install this product on a wall if it
y y
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
y y
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.
IMPORTANT SAFETY INSTRUCTIONS
Preventing Image burn or Burn-in on
your TV screen
If a fixed image displays on the TV screen
y 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.
Watching the TV for a long period of time
y y
with the screen ratio of 4:3 (for the 21:9
model, 4:3 and 16:9) may cause image
burn-in on the letterboxed area of the
screen. When watching the TV for a long
period of time, please use the default
screen ratio of 16:9 or 21:9 depending
upon the product.
Avoid displaying a fixed image on the TV
y 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.
