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 fre-
quently, because subtle ghost images can be left on the picture
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-market tickers—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.
P LACEMENT 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.
C LEANING
• 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.
