SAFETY INSTRUCTIONS
y
When moving or unpacking the product, work in pairs because the product is
heavy.
Otherwise, this may result in injury.
y
Contact the service centre once a year to clean the internal parts of the product.
Accumulated dust can cause mechanical failure.
y
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.
y
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.
y
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.
y
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.
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 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.
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.
