y Displaying a still image (e.g., broadcasting channel logo, on-screen menu,
scene from a video game) for a prolonged time may cause damage to the
screen, resulting in retention of the image, which is known as image sticking.
The warranty does not cover the product for image sticking.
Avoid displaying a fixed image on your television's screen for a prolonged
period (2 or more hours for LCD, 1 or more hours for Plasma).
Also, if you watch the TV at a ratio of 4:3 (4:3 or 16:9 for 21:9 model) for a long
time, image sticking may occur on the borders of the panel. When watching the
TV for a long period of time, please use the default screen ratio.
This phenomenon also occurs in third-party products and is not subject to
exchange or refund.
y 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.
y Do not use high voltage electrical goods near the TV (e.g. electric mosquito-
swatter). This may result in product malfunction.
