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.
