WARNING Concerning Stationary
Images on the TV Screen:
Do not leave stationary or letterbox
images on screen for extended peri-
ods 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 score-
boards
• 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 pric-
ing 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 exam-
ple, 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 abrasive. Do not
use household cleaners. Wipe the
front screen with a clean cloth
dampened with water. Use even,
easy, vertical strokes when clean-
ing.
• Gently wipe the cabinet surfaces
with a clean cloth or sponge damp-
ened 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 ventila-
tion 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.
