Abnormal Display
• If the product feels cold to the touch, there may be a small "flicker"
when it is turned on. This is normal, there is nothing wrong with
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 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 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.
