Although this unit incorporates high precision technology
in its design, please understand that there may be
extremely slight pixel breakup, or light emission fault.
Note
In order to protect the panel and internal circuitry, this display is
provided with a cooling fan designed to turn on/off and change
speed automatically in accordance with ambient temperature
conditions (the fan sound will change in accordance with its
speed).
Additional cautions
• If the power is automatically turned off during operation
of this unit, the following reasons may be the cause.
1
Is the POWER MANAGEMENT or AUTO POWER
OFF function set to ON? (page 24).
2
Is ambient temperature too high?
3
The internal temperature has risen abnormally due to
blocked cooling vents, overheating of internal
electronic parts, or other factors.
4
If the display is moved suddenly from a chilled
location to a warm room, or if the room temperature
rises suddenly, condensation may form on internal
parts. To protect internal circuitry, the display is
provided with a condensation detector that
automatically disables power in event of internal
condensation; in this case, allow the unit to dry
thoroughly before using.
If the power is automatically turned off for a reason
other than the above reasons, there could be a
malfunction. In this case, unplug the power cord from
the power outlet and request repair from your nearest
sales outlet.
• The plasma display panel of this unit is very bright and
viewing it a close distance will cause eye strain.
We recommend that you view the screen from a
suitable distance (9.8 to 19.7 feet (3 to 6m)).
STANDBY/ON indicator
During operation of the Power Management function, the
indicator will flash green at intervals of about 2 seconds
(page 24). If the green light displays a flashing pattern
other than the above, an error message is indicated.
Consult any onscreen messages (page 31) and check
ambient conditions (temperature, condensation, etc.) and
respond accordingly (pages 32 – 33).
If the problem persists, disconnect the power plug and
consult your dealer or a service center.
When STANDBY/ON is pressed to set the unit to the
standby mode, the indicator will flash red for several
seconds (page 19). Other than this, if the power turns off
by itself, or refuses to turn on, or if the red indicator
conditions flashing, a malfunction may be indicated.
Immediately disconnect the power plug and consult your
dealer or a service center.
Additional Information
About the plasma panel’s
protection function
The brightness of this display will deteriorate slightly
when an image with little movement such as a
photograph or computer image is continuously displayed.
This is caused by the plasma panel’s protection function
which detects images with slight movement and
automatically adjusts brightness to protect the display,
and is not a malfunction.
The screen-saver function begins operating when the
display detects no or little screen movement for a period
of about three minutes.
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 electrical load
When image patterns with very high peak luminance are
displayed for more than 1 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.
• The power control function can be set to help prevent
damage from screen burning (page 29).
Note
Special precautions must be employed when using
the plasma display as a surveillance monitor or in
other applications where a fixed image will be
displayed for extended periods of time. Before using
the monitor in such applications, consult your dealer
for advice.
