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.
Power Button does not respond
• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.
• Check the Vacation Switch on the right hand 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 Electronic Displays 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 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 60 Hz refresh rate.
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 warning "OUT OF RANGE" is
displayed: Either signal 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.
LED on monitor is not lit (no green or amber colour can be seen)
• Power Switch should be in the ON position and power cord should be connected.
