• Abnormal Display
- 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.
- This panel is an advanced product that contains
millions of 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.
- Displaying a still image for a prolonged period
of time may cause an image sticking. Avoid
displaying a fixed image on the TV screen for a
extended length of time.
• 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.
• When cleaning the product, be careful not
to allow any liquid or foreign objects to
enter the gap between the upper, left or
right side of the panel and the guide panel.
(Depending upon model)
• Make sure to wring any excess water or
cleaner from the cloth.
• Do not spray water or cleaner directly onto
the TV screen.
• Make sure to spray just enough of water or
cleaner onto a dry cloth to wipe the screen.
