IMPORTANT NOTES

WARNING: Do not leave stationary or letterbox images on-screen for extended periods of time. Mix 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.

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 black or a bright color if you frequently use closed captioning.
