Symptom
Point to check
See
page
•
The temperature of the display panel
surface is high.
•
The plasma display panel is lighting the
phosphors by the discharge of internal
radiation. In some cases, this may cause
the temperature of the panel surface to
increase. Please note that this is not a
malfunction.
-
•
There are locations on the screen that
are different from the periphery (*).
*Points that do not light, points with
brightness different from that of the
periphery, points with color different
from that of the periphery, etc.
•
High-precision technology is used to
manufactue the plasma display panel,
However in some cases, there are minor
defects in some parts of the screen. Please
note that this is not a malfunction.
-
•
Vertical stripes appear, depending on the
screen contents.
•
The plasma display panel is lighting the
phosphors by the discharge of internal
radiation. Depending on the screen
contents, in rare cases this may cause
vertical stripes to appear because of failure
to light. Please note that this is not a
malfunction.
-
•
Coarse horizontal stripes appear in FULL
display.
•
Adjusting the phase will reduce the
horizontal stripes.
(RGB input)
•
The display dims to make the picture
invisible during special playback of a
VCR (FF, REW).
•
This condition may occur when the unit is
connected to a VCR with component output,
such as 480i, but it is not a failure. But when
it occurs, switch to composite output or S1
(S2) output).
-
•
Flickering in the form of horizontal lines
oscillating up and down.
•
If the direct frequency from the computer is
below 85Hz, try a higher frequency (upper
limit 85Hz). There may be a slight
attenuation of the current image.
-
•
The fan motor is noisy.
•
Use the fan that controls the temperature in
the main body to lower the temperature of
this unit. If the ambient temperature is high,
the noise from the motor increases as the
rotation speed increases.This is not a
malfunction.
-
•
The top of the monitor heats up.
•
When used for long periods of time, the top
of the monitor may heat up. This is not a
malfunction.
