Fan motor noise
The rotation speed of the cooling fan motor increases when the
ambient temperature of the plasma display becomes high. You
may hear the sound of the fan motor at that time.
To use this product for a long period of time
Energy Save maintains efficiency of the screen for a long period
of time by decreasing picture brightness and lowering power
consumption. Setting Energy Save to “Mode 1” is recommended
for increased efficiency.
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 each type of definition properly. 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 completed. This
may happen, for example, when you switch between television
and an external digital video recorder
(D-VHS), or when your recorded program switches between
different definition types, while the on-screen menu is being
shown.
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.
Image Retention
When a static image is left frozen 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
moving video.
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
displays). Displaying the same still images for long periods
should be avoided as permanent image retention or burn-in may
occur. Recommended guidelines are as follows:
Do not display static images for long periods (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).
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 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 displaying still images for a period
of time may cause image retention. In most cases, the image
retention can be corrected by displaying bright images for a
similar period of time.
If you display still images on your plasma display for long periods
of time, image retention may be irreparable.
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
more than one minute, after-image lagging may occur due to the
remaining electric load. The after-images remaining on the screen
will disappear when moving images are displayed. The time for the
after-images to disappear depends on the luminance of the still
images and the time they had been 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 of
time 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 will 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
image off to prevent damage from screen burning.
• To minimize image retention, the display position is automatically
changed imperceptibly when watching plasma display.
Some parts of the picture may not be visible (see
Orbiter
on page
63).
Minimizing damage from screen burning
• Set the Side Mask detection function to “On”. The High
Definition 16:9 aspect ratio images containing side masks will
be detected automatically and side masks will be added or the
image displayed in full screen.
• We recommend that you enjoy watching images displayed in full
screen, except when doing so may result in copyright
infringement. The use of images displayed in screen sizes
different from the original video for financial gain or in
broadcasting for public viewing may result in infringement of the
legally enforceable rights of the copyright holder (see page 62).
