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 recom- mended 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.

Check the Vacation Switch on the right 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 of America 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 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).
