1. Here’s a great way to keep the dust off your 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 you turn on your TV.
To remove dirt or dust, wipe the cabinet with a soft, dry, lint-free cloth.
Please do not use a wet cloth.
If you expect to leave your TV dormant for a long time (such as a vacation), it’s a good idea to
unplug the power cord to protect against possible damage from lightning or power surges.
- Early malfunctions can be prevented. Careful and regular cleaning can extend the amount of time you will have
your new TV. Be sure to turn the power off and unplug the power cord before you begin any cleaning.
