MAINTENANCE
Cleaning Your TV
Clean your TV regularly to keep the best
performance and to extend the product lifespan.
y y Make sure to turn the power off and
disconnect the power cord and all other
cables first.
y y When the TV is left unattended and unused
for a long time, disconnect the power cord
from the wall outlet to prevent possible
damage from lightning or power surges.
CAUTION
Screen, frame, cabinet and stand
To remove dust or light dirt, wipe the surface with
a dry, clean, and soft cloth.
To remove major dirt, wipe the surface with a
soft cloth dampened in clean water or a diluted
mild detergent. Then wipe immediately with a dry
cloth.
y y Do not push, rub, or hit the surface with
your fingernail or a sharp object, as this may
result in scratches on the screen and image
distortions.
y y Do not use any chemicals, such as waxes,
benzene, alcohol, thinners, insecticides,
air fresheners, lubricants, as these may
damage the screen’s finish and cause
discoloration.
y y Do not spray liquid onto the surface. If
water enters the TV, it may result in fire,
electric shock, or malfunction.
CAUTION
Power cord
Remove the accumulated dust or dirt on the
power cord regularly.
Preventing “Image burn” or
“Burn-in” on your TV screen
y y If a fixed image displays on the TV screen for
a long period of time, it will be imprinted and
become a permanent disfigurement on the
screen. This is “image burn” or “burn-in” and
not covered by the warranty.
y y If the aspect ratio of the TV is set to 4:3 for a
long period of time, image burn may occur on
the letterboxed area of the screen.
y y Avoid displaying a fixed image on the TV screen
for a long period of time (2 or more hours for
LCD, 1 or more hours for the Plasma TV) to
prevent image burn.
