● Flicker causes stripes to move up and down
(during personal computer signal input).
→
When the vertical frequency of the personal
computer is lower than 75Hz, try increasing the
frequency (upper limit: 75Hz). This may improve
the situation in some cases.
● 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

manufacturing the plasma display panel but, 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
