Troubleshooting - NEC MultiSync LCD1880SX User Manual

Recommended Use
• Position whatever you are looking at most of the time (the screen or reference material) directly in front of you
to minimize turning your head while you are typing.
• Avoid displaying fixed patterns on the monitor for long periods of time to avoid image persistence (after-image effects).
• Get regular eye checkups.
Ergonomics
To realize the maximum ergonomics benefits, we recommend the following :
• Adjust the Brightness until the background raster disappears.
• Do not position the Contrast control to its maximum setting.
• Use the preset Size and Position controls with standard signals.
• Use the preset Color Setting.
• Use non-interlaced signals with a vertical refresh rate between 60-75Hz.
• Do not use primary color blue on a dark background, as it is difficult to see and may produce eye fatigue to
insufficient contrast.

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.
• Check the Vacation Switch should be in the ON position.
• 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.
• Check the signal input, "INPUT 1" or "INPUT 2".
Power Button does not respond
• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor, or
simultaneously press the RESET and Power buttons.
• Check the Vacation Switch on the left side of the monitor.
Image persistence
• Image persistence is when a "ghost" of an image remains on the screen even after the monitor has
been turned off. Unlike CRT monitors, LCD monitors' image persistence is not permanent. To
alleviate image persistence, turn the monitor off for as long as an image was displayed. If an image was
on the monitor for one hour and a "ghost" of that image remains, the monitor should be turned off for one
hour to erase the image.
NOTE : As with all personal display devices, NEC-Mitsubishi Electronics Display recommends using a screen saver at
regular intervals whenever the screen is idle.
Message "OUT OF RANGE" is displayed (screen is either blank or shows rough images only)
• Image is displayed only roughly (pixels are missing) and OSM
clock or resolution is too high. Choose one of the supported modes.
• OSM warning "OUT OF RANGE" is displayed on a blank screen: Signal frequency is out of range. Choose one of the
supported modes.
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 total.
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.
LED on monitor is not lit (no green or amber color can be seen)
• Power Switch should be in the ON position and power cord should be connected.
Display image is not sized properly
• Use the OSM Image Adjust controls to increase or decrease the Coarse total.
• 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.)
No Video
• If no video is present on the screen, turn the Power button off and on again.
• Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).
