Important Notes - Mitsubishi WS-48613 Owner's Manual

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 patterns. Reducing the initial contrast
level can help slow the aging process. 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, and digital TV
tuner/converter boxes.
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
program allows, you should also set your toolbars to the
hidden mode.

IMPORTANT NOTES

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.
Closed Captioning
Mitsubishi recommends using a gray background rather
than black or a bright color if you frequently use closed
captioning.
