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 a TV 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 a TV 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:
74
• 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 standard TV)
• Side bar images
(These are the solid bars shown on each side of the image when
you watch a normal TV program on a widescreen TV)
• 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 logos 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 logos
(Subtle, low-contrast logos 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
