Troubleshooting
No picture
Th
e signal cable should be properly connected to the display
card/computer.
Th
e display card should be properly seated in its slot.
Front Power Switch and computer power switch should be in
the ON position.
Check to make sure that a supported mode has been selected
on the display card or system being used. (Please consult
display card or system manual to change graphics mode.)
Check the monitor and your display card with respect to
compatibility and recommended settings.
Check the signal cable connector for bent or pushed-in pins.
Power Button does not respond
Unplug the power cord of the monitor from the AC outlet to
turn off and reset the monitor.
Image persistence
Please be aware that Plasma Technology may experience a
phenomena known as Image Persistence. Image Persistence
occurs when a residual or “ghost” image of a previous image
remains visible on the screen. Unlike CRT monitors, Plasma
monitors’ image persistence is not permanent, but constant
images being displayed for a long period of time should be
avoided. To alleviate image persistence, turn off the monitor
for as long as the previous image was displayed. For example,
if an image was on the monitor for one hour and a residual
image remains, the monitor should be turned off for one hour
to erase the image.
NOTE: As with all personal display devices, NEC DISPLAY
SOLUTIONS recommends displaying moving images and
using a moving screen saver at regular intervals whenever the
screen is idle or turning off the monitor when not in use.
Image is unstable, unfocused or
swimming is apparent
Signal cable should be properly attached to the Plasma
monitor, computer, or other input device.
Use the OSD screen controls to focus and adjust display by
increasing or decreasing the clock phase total. When the
display mode is changed, the OSD Image Adjust settings may
need to be readjusted.
Check the monitor and your display card with respect to
compatibility and recommended signal timings.
Image of component signal is greenish
Check to see if the DVD/HD input connector is selected.
LED on monitor is not lit
(no green or red color can be seen)
Main Power Switch should be in the ON position and power
cord should be connected.
Red LED on monitor is blinking
A certain failure might have occurred, please contact your
nearest authorized NEC DISPLAY SOLUTIONS service
facility.
