WARNING concerning stationary images on the TV
Screen: Do not leave fi xed images on the screen for extended periods of time. This can cause uneven aging of the Plasma
panel. Normal use of the TV should involve viewing of programs that have constantly moving or changing images. Do
not leave moving images on screen for extended periods of time. Do not display the same images too frequently; if you
do, subtle “ghost” images can be left on the Plasma screen. Sources of stationary images may be Laser discs, video games,
Compact Discs Interactive (CD-i), paused Digital Video Discs (DVDs) or video tapes.
Here are some common examples of stationary images:
• DVD menus list DVD content.
• Letter box black bars that appear at the top and bottom of the TV screen when a wide screen (16:9) movie is viewed
on a TV with standard (4:3) aspect ratio. This occurs with some DVDs.
• Video game images and scoreboards
• Television station logos cause a problem if they are bright and stationary. Moving or low-contrast graphics are
less likely to damage the picture tube.
• Stock market tickers may appear at the bottom of the TV screen if the TV programming covers this news.
• Shopping channel logos, pricing displays may be bright and may appear constantly during the show.
These are usually apper in the same location on the TV screen.
TV Location
• To avoid cabinet warping, cabinet color changes, and an increased chance of TV failure, do not place the TV
where temperatures can become excessively hot -- for example, in direct sunlight or near a heating appliance.
• Allow a free flow of air around the TV.
Cleaning
• To avoid possible shock hazard, remove the TV’s power cord from the electrical outlet before cleaning.
• Regularly dust the TV with a dry, non-scratching duster.
• When cleaning the TV, take care not to scratch or damage the screen surface. Avoid wearing jewelry or using
anything abrasive. Do not use household cleaners. Wipe the screen with a clean cloth dampened with water.
Use even, easy, vertical strokes when cleaning.
• Occasionally vacuum the vents on the rear of the TV.
• Never use thinners, insecticide sprays, or other chemicals on or near the cabinet. They may permanently blemish
the cabinet.
Care And Cleaning
After-images appear
Do not allow a still picture to be displayed for an extended
period, as this can cause a permanent after-image to remain
on the Plasma TV.
Examples of still pictures include logos, video games,
computer images, and Teletext.
Note:
The permanent after-image on the Plasma TV resulting from
fixed image use is not an operating defect and as such is not
covered by the Warranty.
This product is not designed to display fixed images for
extended periods of time.
