WARNING: Do not leave stationary or letterbox images on-screen for
extended periods of time. Mix types of pictures shown. Uneven phosphor
aging is NOT covered by your warranty.
The normal use of a TV should include a mixture of TV pic-
ture types. The most frequently used picture types should fill
the screen with constantly moving images rather than sta-
tionary 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. To avoid this, mix your viewing pat-
tern. 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 fill the screen
whenever possible.
This plasma TV is a phosphor-based display. As is the case
with any phosphor-based display (like a CRT TV/monitor, for
example) light output will gradually decrease over the life of
a plasma display panel. Normal TV pictures fill the screen
with constantly changing images. Under these conditions,
phosphor-based displays 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 used in plasma displays and can leave subtle
ghosts of the stationary images in the picture.
When using a computer or similar device through a VGA
input, be sure to turn on the Screen Saver feature and set
the activation time to 5 minutes or less. If your computer pro-
gram allows, you should also set your toolbars to the hidden
mode.
Still or stationary images may be received from broadcast-
ers, cable channels, satellite channels, DVD discs, video
tapes, laser discs, on-line services, web/internet searching
devices, video games, and digital TV tuner/converter boxes.
Examples of these types of images include, but are not lim-
ited 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 watching a standard (4:3) program on a
widescreen (16:9) TV.
• Stock-market report bars: ticker running at the bottom of
the TV screen.
• Shopping channel logos & pricing displays: bright
graphics that are shown constantly 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.
• Closed Caption Backgrounds: When set to black or
bright color.
