Part IV: Operation
IMPORTANT NOTES #2
Warning: Do not leave stationary or letterbox images on-screen for
extended periods of time. Mix the types of pictures shown.
Uneven picture tube aging is NOT covered by your warranty.
The normal use of a TV should include
a mixture of TV picture types. The most
frequently used picture types should ll
the screen with constantly moving images
rather than stationary images or patterns.
Displaying the same stationary patterns
over extended periods of time, or display-
ing the same stationary pattern frequently
can leave a subtle but permanent ghost
image. To avoid this, mix your viewing
pattern. Do not show the same stationary
image for more than 15% of your total TV
viewing in any one week. Display con-
stantly moving and changing images that
ll the scr een wh enever possi bl e.
This projection TV uses picture tubes to
project the image to the screen. All
picture tubes age with use. As they
age, their light output is gradually reduced.
Normal TV pictures ll the scr een wi th
constantly changing images. Under these
conditions, picture tubes age at an even
rate across the entire screen. This main-
tains a TV picture that is evenly bright over
the whole screen. Stationary images or
images that only partially ll the scr een
(leaving black or colored bars to ll the
screen), when used over extended periods
of time or when viewed repeatedly, can
cause uneven aging of the phosphors
and leave subtle ghosts of the stationary
images in the picture.
Still or stationary images may be received
from broadcasters, cable channels, sat-
ellite channels, DVD discs, video tapes,
laser discs, on-line services, web/internet
searching devices, video games, and digi-
tal TV tuner/converter boxes. Examples of
these types of images can be, but are not
limited to the following:
Letterbox top/bottom black bars:
shown at the top and bottom of the TV
screen when you watch a widescreen
(16:9) movie on a standard (4:3) TV.
Side bar images: solid bars shown
on each side of an image when watch-
ing a standard (4:3) program on a wi-
descreen (16:9) TV.
Stock-market report bars: ticker run-
ning at the bottom of the TV screen.
Shopping channel logos & pricing dis-
plays: bright graphics that are shown con-
stantly or repeatedly in the same location.
Video game patterns and scoreboards
Bright station logos: moving or low-
contrast graphics are less likely to cause
uneven aging of the picture tubes.
On-line (internet) web sites: or any
other stationary or repetitive computer style
images.
