background, horizontal noise
and incorrect position

Maintenance
Early malfunction can be prevented. Careful and regular cleaning can extend
the amount of time you will have with your new TV. Be sure to turn the power off
and unplug the power cord before you begin any cleaning.
Clean the screen
A great tip to dust off your screen: wet a soft cloth in a mixture of lukewarm
water and a little fabric softener or dish washing detergent. Wring the cloth until
it's almost dry, and then use to wipe the screen.
Make sure the excess water is off the screen, then let air-dry before you turn on
the TV.
Cleaning the cabinet
To remove dirt or dust, wipe the cabinet with a soft, dry, line-free cloth. Please
be sure not to use a wet cloth.
