You may find different brightness and colour of the panel de-
y
pending 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 (e.g., broadcasting channel logo, on-screen menu,
y
scene from a video game or computer screen) for a prolonged time may
cause damage to the screen, resulting in retention of the image, which is
known as image sticking. It can remain for long time or never disappear.
The warranty does not cover the product for image sticking. Avoid display-
ing a fixed image on your television's screen for a prolonged period (1 or
more hours for OLED).
Also, if you watch the TV at a ratio of 4:3 for a long time, image sticking
may occur on the borders of the panel.
This phenomenon also occurs in third-party products and is not subject to
exchange or refund.
Generated Sound
y
"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 gen-
erated 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 mosqui-
y
to-swatter). This may result in product malfunction.
