TROUBLESHOOTING (continued)
Symptoms That Seemingly Appear to be Failures (continued)
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 manufacture 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.
(PC INPUT MODE only)
• 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.
• Try turning the FILTER ON. For this case however, the vertical
resolution will drop.
• 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 air temperature
increases, the fan will start, the RPMs will increase and motor
noise will grow louder. This is not a malfunction though.
-
• 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.
-
• Text characters are displayed with varying thicknesses. • The thicknesses of characters and lines may vary if images with a
vertical resolution greater than 512 lines are displayed; however,
this is not a malfunction.
