ENGLISH

7

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.

Some horizontal lines may appear when the Clear Panel Noise feature is 
performed. It is normal and there is no need to be concerned.

Generated Sound 

“Cracking” noise: A cracking noise that occurs when watching or turning 
off the TV is generated by plastic thermal contraction due to tempera-
ture 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.

Do not use high voltage electrical goods near the TV(e.g. electric 
mosquito-swatter). This may result in product malfunction.
