SAFETY INSTRUCTIONS 8
ENG
ENGLISH y When moving the product, make sure you turn the power off first. Then, unplug the power
cables, antenna cables and all connecting cables.
The TV set or power cord may be damaged, which may create a fire hazard or cause
electric shock.
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 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 colour 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 depend-ing
on the product.
This generated sound does not affect the performance and reliability of the product.
