WARNING concerning stationary images on the TV
screen: Do not leave fixed images on the screen for
extended periods of time.This can cause uneven aging
of the picture tube.
Normal use of the TV should involve viewing of programs that
have constantly moving or changing images. Do not leave non-
moving images on screen for extended periods of time. Do not
display the same images too frequently; if you do, subtle “ghost”
images can be left on the picture tube. Sources of stationary
images may be Laser discs, video games, Compact Discs
Interactive (CD-i), or paused Digital Video Discs (DVDs) or
videotapes.
Here are some common examples of stationary images:
• DVD menus list DVD content.
• Letterbox black bars appear 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. This is available
with some DVDs.
• Video game images and scoreboards
• Television station logos cause a problem if they are
bright and stationary. Moving or low-contrast graphics are
less likely to damage the picture tube.
• Stock market tickers may appear at the bottom of the
TV screen if the TV programming covers this news.
• Shopping channel logos, pricing displays may be
bright and may appear constantly during the show.These
are usually in the same location on the TV screen.
TV Location
•
To avoid cabinet warping, cabinet color changes, and an
increased chance of TV failure, do not place the TV where
temperatures can become excessively hot (for example, in
direct sunlight or near a heating appliance).

To avoid possible shock hazard, remove the TV’s power
cord from the electrical outlet before cleaning.

with a clean cloth dampened with water. Use even, easy,

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.
