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.

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.
