LG UB85 Series Owner's Manual page 9

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.
SAFETY INSTRUCTIONS
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.
