WARNING Concerning Stationary Images on the TV
Screen:
Do not leave stationary or letterbox images on the
screen for extended periods of time. This can cause
uneven picture tube aging.
Normal use of the TV should involve showing pictures that con-
tain constantly moving and changing images that fill the screen.
Do not leave non-moving images on the screen for extended
periods of time or display the same images on the screen too
frequently. Subtle ghost images can be left on the picture tube.
Sources of stationary images may be DVDs, laser discs, video
games, CD-i discs, videotapes, digital television boxes, broad-
cast 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 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 a 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
•

—
presented at the bottom of the TV
screen
•
Shopping channel logos and pricing displays
—
bright
and show constantly or repeatedly in the same location on the

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, non-scratching 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
abrasive. 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.
No Power
• Check the TV power cord. Unplug the power cord, wait 10
seconds, then reinsert the plug into the outlet and push the
POWER button again.
• Check that the outlet is not on a wall switch.

being used.
No Picture
