Symptoms That Seemingly Appear to be Failures (continued)
See page
Point to check
Symptom
• 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 colour different from
that of the periphery, etc.
• Vertical noises 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.
• The screen becomes dark and the images cannnot be seen
during VTR special playback (fast forward, rewind)
• During multi picture mode, sub pictures are not displayed.
• The screen display sizes are not switched.
• Images from AV6 (HDMI) are not displayed.
• 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.
• This sometimes occurs when a component output VTR such
as the 480i is connected.
This is not a malfunction; therefore, please take note that this
may occur. When it does occur, change to composite
output,or S.video output.
• Sub pictures image might not be able to be displayed,
depending on the combination.
(Refer to the table of “2 pictures mode” and “4 pictures
mode”)
• The screen display size is fixed at “Full” as receiving 1080i/
60Hz, 1080i/50Hz, 720p/50Hz, and 720p/60Hz.
• Check the cable and output format of connecting device.
(Refer to “Connecting to an Audio Visual Device” and
“Recommended Signal List”.)
