that contain constantly moving and changing images that fill the
screen. Be careful no
t 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 screen. Sources of stationary images may be DVD
disks, laser disks, video games, cd-i disks, videotapes, digital
television boxes, br
oadcast channels, cable channels, satellite
channels, and o
thers. Here are some examples of stationary

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.

bright and stationary; moving or low-contrast graphics are
less likely to cause uneven aging of the picture tube.

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 c hanges, 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.

To avoid possible shock hazard, unplug the TV 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 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.

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
