Troubleshooting - NEC LCD3000 User Manual

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
• 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 Europe recommends using a screen saver
at regular intervals whenever the screen is idle.
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).
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.
Either light vertical or horizontal stripes may appear, depending on the specific display pattern. This is no product fault or
degradation.
