IMPORTANT SAFETY INSTRUCTIONS

Dot Defect
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
“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 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.

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
y
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
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, 1
or more hours for the Plasma TV) to prevent image
burn.
