CARE AND CLEANING OF THE TV

WARNING Concerning Stationary Images on the TV Screen:

Do not leave picture border bars or stationary images on screen for extended periods of time.This can cause uneven picture tube aging.

Normal use of the TV should involve the showing of pictures that contain constantly moving and changing images that fill the screen. Be careful not to leave nonmoving images on screen for extended periods of time, or to display the same images on screen too frequently, because subtle ghost images can be left on the picture tubes. Avoid showing pictures with border bars or the same stationary images more than 15 percent of your total viewing in any one week. Sources of stationary images may be broadcast channels, cable channels, satellite channels, digital television boxes, DVD discs, laser discs, video games, CD-i discs, videotapes, and others. Here are some examples of stationary images (this is not an all-inclu-

sive list; you may encounter others in your viewing): Border bars—solid bars shown when viewing a standard (4:3) picture and some widescreen movies on your widescreen (16:9) TV; DVD menus—listings of DVD disc content; Video-game images and score- boards; Television station logos—present a problem if they are bright and stationary; moving or low-contrast graphics are less like- ly to cause uneven aging of the picture tube; Stock-markettickers—presented at the bottom of the TV screen; Shopping channel logos and pricing displays—bright and shown constantly or repeatedly in the same location on the TV screen.

All picture tubes age with use, with their light output diminishing over time. But by maintaining normal use—mixing television picture types—you will create conditions in the tubes age at an even rate. The result will be a TV picture that is evenly bright over the entire screen.

WARNING

To avoid possible shock hazard, be sure the TV is unplugged from the electrical outlet before cleaning.

Be sure the TV is unplugged before cleaning it.

Cleaning the Cabinet

•Regularly dust the TV cabinet with a dry, nonscratching duster.

•Gently wipe the cabinet surfaces with a soft, clean cloth. Even if the surfaces are very dirty, do not apply cleaner to them directly. Soak the cloth in a solution of cool, clean water and mild soap or deter- gent. Wring out the cloth and wipe the cab- inet surfaces clean. Then use a clean, dry cloth to dry the wiped surfaces.

•Occasionally vacuum the ventilation slots on the back cover of the set. See the next section on “Cleaning or Replacing the Filters.”

•Never use thinners, insecticide sprays, or other chemicals on or near the cabinet, as they might cause permanent marring of the cabinet finish.
