Troubleshooting
No picture
• The signal cable should be completely connected to the
display card/computer.
• The display card should be completely 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 LCD Technology may experience a
phenomenon 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, LCD 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 completely attached to the
computer.
• Use the OSM Image Adjust controls to focus and adjust
display by increasing or decreasing the fine adjustment.
When the display mode is changed, the OSM Image
Adjust settings may need to be re-adjusted.
• Check the monitor and your display card with respect to
compatibility and recommended signal timings.
• If your text is garbled, change the video mode to non-
interlace and use 60Hz refresh rate.
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 colour can be seen)
• Power Switch should be in the ON position and power
cord should be connected.
• Make certain the computer is not in a power-saving
mode (touch the keyboard or mouse).
RED LED on monitor is blinking
• A certain failure might have occurred, please contact
your nearest authorized NEC DISPLAY SOLUTIONS
service facility.
Display image is not sized properly
• Use the OSM Image Adjust controls to increase or
decrease the coarse adjustment.
• 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.)
Selected resolution is not displayed properly
• Use OSM Display Mode to enter Information menu and
confirm that the appropriate resolution has been
selected. If not, select corresponding option.
No Sound
• Check to see if speaker cable is properly connected.
• Check to see if mute is activated.
• Check to see if volume is set at minimum.
Remote Control is not available
• Check the Remote Control’s batteries status.
• Check if batteries are inserted correctly.
• Check if the Remote Control is pointing at the monitor’s
remote sensor.
• Check the Remote Control Mode status.
• The remote control system may not function when direct
sunlight or strong illumination strikes the remote control
sensor of the LCD monitor, or when there is an object in
the path.
“SCHEDULE”/“OFF TIMER” function is not working
properly
• The “SCHEDULE” function will be disabled when the
“OFF TIMER” is set.
• If the “OFF TIMER” function is enable and the power to
the LCD monitor is turned off if the power supply is
interrupted unexpectedly, then the “OFF TIMER” will be
reset.
PIP (Picture In Picture) does not work
• Check the resolution of the input signal. PIP does not
work with all types of “1080i” input signals. The PIP
function will work with 1080p signals.
RS232-C is not working
• Make sure the monitor is not in “Eco Standby” mode
(see page 27).
Snowy Picture, Poor Sound in TV
• Check antenna/cable connection. Use new cable if
necessary.
Interference in TV
• Check components for shielding, move away from
monitor if necessary.
Either light vertical or horizontal stripes may appear, depending on the specific display pattern. This is no product fault or
degradation.
