Troubleshooting
No picture
• The signal cable should be properly connected to the display card/computer.
• The 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 LCD 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, 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-Mitsubishi Electronics Display recommends 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 LCD monitor, computer, or other input device.
• Use the OSM screen controls to focus and adjust display by increasing or decreasing the clock phase total. When the display mode
is changed, the OSM Image Adjust settings may need to be readjusted.
• 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 color can be seen)
• Main 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-Mitsubishi Electronics Display service facility.
Display image is not sized properly
• Use the OSM screen controls to increase or decrease the clock 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.)
Selected resolution is not displayed properly
• Use OSM information to enter Information menu and confirm that the appropriate resolution has been selected. If not, select
appropriate resolution.
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
• Test the Remote Control's batteries for strength/life.
• Check if the batteries are inserted correctly.
• Check if the Remote Control is pointed at the monitor's remote sensor.
"SCHEDULE" / "OFF TIMER" functions not working properly
• The "SCHEDULE" function will be disabled when the "OFF TIMER" is set.
• If the "OFF TIMER" function is enabled and the power to the LCD monitor is turned off or if the power supply is interrupted unexpectedly,
then the OFF TIMER will be reset.
Light vertical or horizontal stripes may appear depending on different display patterns. This is no product fault or degradation.
