y Contact the service centre
y
once a year to clean the
internal parts of the product.
Accumulated dust can cause
mechanical failure.
y Refer all servicing to
y
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
y
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
y
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
y
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.
SAFETY INSTRUCTIONS
y Displaying a still image (e.g., broadcasting
y
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
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 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.
