Maintenance

Cleaning your TV
Clean your TV regularly to keep the best performance and to extend
the product lifespan.
y Make sure to turn the power off and disconnect the power cord and
all other cables first.
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.
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 Avoid touching the screen at all times, as this may result in damage
to the screen.
y Do not push, rub, or hit the screen surface with your fingernail or a
sharp object, as this may result in scratches and image distortions.
y Do not use any chemicals as this may damage the product.
y Do not spray liquid onto the surface. If water enters the TV, it may
result in fire, electric shock, or malfunction.
Power cord
Remove the accumulated dust or dirt on the power cord regularly.
Preventing "Image burn" or "Burn-in"
on your TV screen
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 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 Avoid displaying a fixed image on the TV screen for a long period of
time (2 or more hours for LCD) to prevent image burn.
