Cautions and Warnings
In rare cases, some pixels can be permanently switched off, or on, resulting in either a black or colored pixel
permanently fixed on the screen. This effect is common to all plasma displays because it is a consequence of the
technology.
If the defective pixels are visible at the standard viewing distance of between 2.5 and 3.5 meters (8.2 feet and 11.5
feet) while viewing a normal broadcast (i.e. not a test card, still image, or single color display) please immediately
contact Pioneer Customer Support (USA) or Customer Satisfaction (CANADA). See inside back cover for contact
information. If, however, the faulty pixels can only be seen close up or during single color displays then this is
considered normal for this technology.
Image Retention (a.k.a. Burn-In)
Leaving a static picture on screen for several hours can cause a faint imprint of the image. This imprint is known as
image retention or burn-in. The image may be temporary or permanent. Although caused by different things, image
retention can occur on all display technologies including LDC, plasma, direct view CRT TVs, and projection TVs.
On today's plasma displays, permanent image retention is less of a worry. Most image retention can be improved
simply by watching something with a lot of action or rapid screen changes. To avoid image retention as much as
possible, refer to the guidelines below.
• Change the picture periodically when showing static images, such as a fixed image from a PC or a TV game
unit, for longer periods.
• Avoid leaving fixed images such as time of day indicator or channel logos on screen whenever possible.
• Display content in a wide aspect ratio (no black or gray bars on any side of the content). This flat panel TV is
equipped with multiple wide-screen viewing modes; use one of these modes to fill the entire screen with
content. View in a wide aspect ratio unless doing so would be a copyright infringement.
• Set the Side Mask detection function to Mode 1 or Mode 2. High Definition 16:9 aspect ratio images
containing side masks are detected automatically and side masks are added or the image appears in full-
screen.
• Avoid showing dark images after still images for a period of time. In most cases, any image retention caused
by this sequence can be corrected by displaying bright images for a similar period of time.
After-Image Lag
Displaying the same images such as still images for a long time may cause after-image lagging. After-Image Lag
refers to a ghost of the still image remaining visible after the picture is no longer being shown. This may occur in
the following cases.
• After-image lagging due to remaining electric load
If an image with very high peak luminance is displayed for more than a minute, after-image lagging may
occur due to the remaining electric load. The ghost-image remaining on the screen disappears when
moving images are shown. The luminance of the still image and the length of time it was displayed
determine how long it takes for the ghost image to fade away.
• After-image (lag image) due to burning
Avoid displaying the same image on the flat panel TV continuously over a long period. If the same image is
displayed continuously for several hours, or for shorter periods over several days, a permanent after-image
may remain on the screen. This after-image is permanent because the fluorescent materials burned.
Burned images may fade eventually after playing other video sequences but do not disappear completely.
When a program menu, or frozen image is displayed for up to 10 minutes, the flat panel TV automatically turns
the image off to prevent the screen from being burned.
Screen Protection
Screen Protection simultaneously optimizes the related settings to alleviate image retention. For details, see
"3.6.2 Extend Your Panel Life."
Image Orbiter
Another built-in feature to protect against burn-in is the Orbiter function. Orbiter automatically changes the
position of the picture imperceptibly while the image is on screen. For more information about the feature, refer
to "3.6.3 Turn On the Image Orbiter."
