TV Displays white lines in letterbox when viewing a DVD disc

•Some DVD Discs are encoded with as much as 30% more video information to give the best possible picture quality. With the DVD Player in the 16:9 picture format, the play- back of this type of disc with extra video information, can produce a number of small white lines in the upper portion of the black letterbox area. With some of these discs, this sit- uation is unavoidable and it does not require a service call.

CLEANING AND CARE

WARNING Concerning Stationary Images on the TV Screen:

Do not leave stationary or letterbox 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 pic- ture tubes. Sources of stationary images may be DVD disks, laser disks, video games, CD-i disks, videotapes, digital television boxes, broadcast channels, cable channels, satellite channels, and others. Here are some examples of stationary images (this is not an all-inclusive list; you may encounter others in your viewing):

•DVD menus—listings of DVD disk content

•Letterbox black bars—shown at the top and bottom of the TV screen when a wide screen (16:9) movie is viewed on a TV with standard (4:3) aspect ratio.

•Video-game images and scoreboards

•Television station logos—present a problem if they are bright and stationary; moving or low-contrast graphics are less likely 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.

Placement of the TV

•To avoid cabinet warping, cabinet color changes, and increased chance of set failure, do not place the TV where temperatures can become excessively hot; for example, in direct sunlight or near a heating appliance.

•Be sure to allow a free flow of air to and from the perforated back cover of the set.

Cleaning

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

•Regularly dust the TV with a dry, nonscratching duster to keep the TV clean.

•When cleaning the TV, take care not to scratch or damage the screen surface. Avoid wearing jewelry or using anything abra- sive. Do not use household cleaners. Wipe the front screen with a clean cloth dampened with water. Use even, easy, vertical strokes when cleaning.

•Gently wipe the cabinet surfaces with a clean cloth or sponge dampened in a solution of cool, clear water and a mild soap or detergent. Use a clean, dry cloth to dry the wiped surfaces.

•Occasionally vacuum the ventilation holes or slots in the back cover of the set.

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