Abnormal Display
• If the product feels cold to the touch, there may be a small “icker”

product.
• 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 1ppm on the panel. This does not indicate a
malfunction and does not aect 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 nd dierent brightness and color of the panel depending
on your viewing position(left/right/top/down).

image sticking. Avoid displaying a xed image on the TV screen for

Generated Sound
• “Cracking” noise: A cracking noise that occurs when watching or
turning o 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 aect the
performance and reliability of the product.
