Care and Cleaning
CAUTION: Turn OFF your TV before cleaning.
You can clean the TV as required, using a soft lint-free cloth. Be sure to occasionally dust the ventilation slots
in the cabinet to help assure adequate ventilation.
The TV’s screen may be cleaned with a soft, lint-free cloth as well. Take care not to scratch or mar the screen. If
necessary, you may use a cloth dampened with warm water.
Never use strong cleaning agents, such as ammonia-based cleaners, or abrasive powder. These types of
cleaners will damage the TV.
While cleaning do not spray liquid directly on the screen, or allow liquid to run down the screen and inside the
TV. Also, avoid placing drinks or vases with water on top of the TV. This could increase the risk of fire or shock
hazard or damage to the TV.
Caution: If fixed (non-moving) images are left on the screen for long periods, they may be permanently imprinted on the
screen. Such images include network logos, phone numbers, and video games. This damage is not covered by your
warranty. Extended viewing of channels displaying these images should be avoided.
