LG 40UH61 Series Owner's Manual page 9

This panel is an advanced product that contains
millions of pixels. You may see tiny black dots
and/or brightly coloured dots (red, blue or
green) at a size of 1 ppm on the panel. This does
not indicate a malfunction and does not affect
the performance and reliability of the product.
This phenomenon also occurs in third-party
products and is not subject to exchange or
refund.
You may find different brightness and color
of the panel depending on your viewing
position(left/right/top/down).
This phenomenon occurs due to the
characteristic of the panel. It is not related
with the product performance, and it is not
malfunction.
Displaying a still image for a prolonged period
of time may cause image sticking. Avoid
displaying a fixed image on the TV screen for a
long period 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 tempera-ture 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.
Do not use high voltage electrical goods near
the TV (e.g. electric mosquito-swatter). This
may result in product malfunction.
