Maintenance

Routine TV Cabinet and Screen Cleaning
Careful and regular cleaning can extend the the useful service life of the TV. Be sure to turn the power off and pull out the
power cord before you begin any cleaning.
Screen Cleaning
1. Here's a great way to keep the dust off the screen for a while. 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 it to wipe the screen.
2. Make sure the excess water is off the screen, and then let it air-dry before turning it on.
Cabinet Cleaning
1. Use a soft cloth with a mild soap solution to wipe the cabinet. (Avoid using any harsh, industrial strength variety of
cleaner.)
2. Rinse the cloth and wipe the cabinet again.
3. Let the cabinet air-dry before turning the TV on.
Extended Absence
If the TV will be dormant for a long time, it's a good idea to unplug the power to protect against possible damage from
lightning or power surges. If you use an off-air antenna, you may also want to disconnect it from the back of the TV.
If you unplug the TV, you may have to reset the clock using the Clock Set menu described earlier. See page 28.
