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 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.
•
When cleaning the product, be careful not to allow any liquid or foreign objects to
enter the gap between the upper, left or right side of the panel and the guide panel.
(Depending on model)
•
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.
