Abnormal Display
•

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.
