Warning:
Do not leave stationary PIP/POP, or letterbox images on the 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 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 subtle but
permanent ghost images. To avoid this, mix your
viewing pattern and reduce the initial contrast level.
Do not show the same stationary image for more
than 15% of your total TV viewing in any given week.
Display constantly moving and changing images
that fill the screen whenever possible.
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 fill the screen with constantly
changing images. Under these conditions, 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 from the stationary images in the
picture.
Still or stationary images may be received from
broadcasters, cable channels, satellite channels,
DVD discs, video tapes, laser discs, on-line
services, web/Internet searching devices, video
games, digital TV tuner/converter boxes and
karaoke machines.
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 watching a standard (4:3) program on a
widescreen (16:9) TV.
News and 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.
Online (Internet) websites
Or any other stationary or repetitive computer
style images, including digital photos or
computer applications/programs.
Closed Captioning
Mitsubishi recommends using a gray
background rather than a black or a bright
color if you frequently use closed captioning.
