Important
Notes
Warning:
Don't leave stationary
or letterboxed
images on-screen
for extended
periods of time.
Mix the types of pictures
shown.
The normal use of aTV should include a mixture of television picture types. The most used
pictures types should fill the screen with constantly moving images rather than stationary images
or patterns. Displaying the same stationary patterns over extended periods of time, or displaying
the same stationary pattern frequently can leave a subtle but permanent ghost image in your
picture.
Note that moving images with stationary black bars can also 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 constantly moving and changing
images that fill the screen whenever possible.
This projection
television 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 television pictures fill the
screen with constantly changing images. In these conditions, the picture tubes age at an even rate
across the entire screen. This maintains aTV picture that is evenly bright over the whole screen.
Stationary images or images that only partially fill the screen (leaving black or colored bars to fill
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.
Uneven
picture tube aging is not covered
by the warranty.
Still or stationary images may be received from broadcasters, cable channels or satellite channels,
DVD discs, video tapes, laser discs, on-line services or web/internet
searching devices, video games
and digital television tuner/converter
boxes. Examples of these types of image can be, but are not
limited to the following:
• Letterbox
top/bottom
black bars
(These are the black bars shown at the top and bottom
of the
screen when you watch a widescreen movie on a standardTV)
• Side bar images
(These are the solid bars shown on each side of the image when
you watch a normaITV
program on a widescreenTV)
•
Stock-market
report
bars
(These are the row of stock prices normally shown at the
bottom of the screen during a financial report)
•
Shopping
channel Iogos and pricing displays
(Especially bright displays that are shown constantly or repeatedly
in the same place on the screen)
•
Video game patterns
or scoreboards
•
Bright station
Iogos
(Subtle, low-contrast
Iogos are less likely to cause uneven aging,
especially if they are translucent and are not always projected in
the same spot)
•
On-line
(internet)
web sites
or other computer style images that are not changed or are left
on display for long periods of time
