Symptoms That Appear to be Failures (continued)
Symptom
• The temperature of the display panel surface is high.
• There are points (*) on the screen that differ in color from
the periphery of the screen.
*Points that do not light, points with brightness different
from that of the periphery, points with color different from
that of the periphery, etc.
• Vertical stripes appear, depending on the screen contents.
• Coarse horizontal stripes appear in FULL display.
• Flickering in the form of horizontal lines oscillating up and
down.
(PC INPUT MODE only)
• The top of the monitor heats up.
• Text characters are displayed with varying thicknesses.
Point to check
• Plasma display panel is lighting the phosphors in the display
panel 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.
• 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.
• 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.
• Adjusting the Clock Phase will reduce the horizontal stripes.
(RGB input)
• 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 Vertical Filter On. For this case however, the
vertical resolution will drop.
• When used for long periods of time, the top of the monitor may
heat up. This is not a malfunction.
• 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.
