, to ).
No image display and no sound is produced.
• Check if the product is turned on.

• Check if there is a problem in the wall outlet by connecting other
products.
The TV turns off suddenly.
• Check the power control settings. The power supply may be
interrupted.

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 1ppm 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 colour 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.
• 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.
