Maintenance

Early malfunctions can be prevented. Please read pages 2, 3, and 4 in the front of the manual and follow the recommendations provided. Careful and regular cleaning can enhance the appearance of your new TV. Be sure to turn the power off and pull the plug out of the power outlet before you begin any cleaning.

SCREEN CLEANING

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.

CABINET CLEANING

1.Use a soft cloth with a mild soap solution to wipe the cabinet.

2.Rinse the cloth and wipe the cabinet again.

3.Let the cabinet air-dry before turning the TV on.

WOOD CABINETS

Use a quality wood cleaner and polish. This will protect the TV from dirt and dust, as well as keep the cabinet looking new.

EXTENDED ABSENCE

If you intend 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. If you use an off-air antenna, you may also want to disconnect it from the back of your TV before leaving.
