When moving or unpacking the product, work in pairs because the product
is heavy.
Otherwise, this may result in injury.
Contact the service centre once a year to clean the internal parts of the
product.
Accumulated dust can cause mechanical failure.
Refer all servicing to qualified service personnel. Servicing is required
when the apparatus has been damaged in any way, such as power supply
cord or plug is damaged, liquid has been spilled or objects have fallen into
the apparatus, the apparatus has been exposed to rain or moisture, does
not operate normally, or has been dropped.
If the product feels cold to the touch, there may be a small "flicker" when it
is turned on. This is normal, there is nothing wrong with product.
The panel is a high technology display product with resolution of two
million to six million 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 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 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.
