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. 
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.
