• You may find different brightness and color 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 (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 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
"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 depend-ing on the product.
This generated sound does not affect the performance and reliability of the product.
