Important Information

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.
