About the menu window size following video
format switch
The video program that you watch may be high definition (HD)
or standard definition (SD). This Plasma Display is designed to
scale to either HD or SD signals. If the video program’s
definition type changes while a menu window is displayed on
the screen (for example: HD → SD or SD → HD), the menu size
may temporarily shrink or enlarge until the scaling is complete.
For example, switching between a TV program and an external
digital video recorder (D-VHS) while viewing a menu can cause
the menu window size to fluctuate.
If this happens, the menu will return to its normal size after two
to three seconds. This action is normal, and does not indicate
a problem with your Plasma Display Panel.
Image Retention
When a static image is shown on a display for several hours, a
faint imprint of the image, known as image retention, can
remain. This image retention may be temporary or permanent.
Although caused by different things, image retention can
occur on all display technologies, including plasma and LCD.
On today’s plasma displays, permanent image retention is less
of a worry. Most image retention can be improved simply by
watching a motion video sequence.
Image retention, also known as burn-in, can occur in all
phosphor-based display systems (including CRT television
systems–both direct view and projection–as well as plasma
display systems). To avoid image retention or burn-in, do not
show a still image for an extended period. Recommended
guidelines are as follows:
• Do not display static images such as still images, fixed
images from PC or TV game equipment, and/or fixed images
such as time of day indicator or channel logo display for long
periods.
• Do not display content in the 4:3 aspect ratio (black or gray
bars on left and right side of content) or letter-box content
(black bars above and below content) for extended periods of
time, or use either of these viewing modes repeatedly within
a short period of time. This plasma display system is
equipped with multiple wide-screen viewing modes; use one
of these screen modes to fill the entire screen with content.
• Displaying dark images after showing a still image for an
extended time may cause image retention. In most cases,
the image retention can be corrected by displaying bright
images for a similar period of time.
Warning: Displaying a still image on the panel for a long period
of time can cause the image to be burned in to the screen
permanently.
CAUTION
Panel sticking and after-image lag
• Displaying the same images such as still images for a long
time may cause after-image lagging. This may occur in the
following two cases.
1 After-image lagging due to remaining electric load
When image patterns with very high peak luminance are
displayed for more than one(1) minute, after-image lagging
may occur due to the remaining electrical load. The after-
images remaining on the screen disappears when moving
images are shown. The time for the after-images to disappear
depends on the luminance of the still image and the length of
time displayed.
2 After-image (lag image) due to burning
Avoid displaying the same image on the Plasma Display
continuously over a long period of time. If the same image is
displayed continuously for several hours, or for shorter periods
but over several days, a permanent after-image may remain on
the screen due to burning of the fluorescent materials. Such
images may become less noticeable if moving images are later
displayed but they do not disappear completely.
NOTE
• When a program menu, TV Guide screen or frozen image is
displayed for 5 to 10 minutes, the system automatically turns
the screen off to prevent damage from screen burning.
• To prevent screen burning, the display position is
automatically changed slightly when the power is switched
on or the input changed. Depending on the broadcast
content, some parts of the picture may not be visible.
Preventing damage from screen burning
• Please show images in full screen unless doing so causes
copyright infringement. See page 65.
• The Energy save function can be set to help prevent screen
burn-in. See page 63.
