Chapter 4 – Troubleshooting

If you are experiencing trouble with the video of your touchmonitor, refer to the following excerpt from page 17 of the original NEC users manual. If the problem persists, please contact your local dealer or our service center.

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.

Power Button 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 that the BNC/D-SUB button is in the correct position.

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.

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 persis- tence 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 Technologies 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 OSMImage Adjust controls to focus and adjust display by

increasing or decreasing the Fine control. 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 Button 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 has a green cast to it

Select “TYPE” in the OSM Information menu and press theor Control button.

Display image is not sized properly

Use the OSM Image Adjust controls to increase or decrease the H. Size.

Check to make sure that a supported mode and signal timing has been selected on the display card or system being used. (Please consult display card or system manual to change graphics mode or refresh rate.)

Selected resolution is not displayed properly

Select the Display Resolution in the OSM Information menuto confirm that the appropriate resolution has been selected. If not, select corresponding option by pressing theorControl button.

If you are experiencing trouble with the touch screen of your touchmonitor, ensure that the touch screen cable is properly attached. If the problem persists, please contact your local dealer or our service center. You may also seek online support at our website: www.elotouch.com.
