SOURCE: NEC Monitor LCD1700V
I had a similar problem with a NEC LCD1935, and I traced it to the inverter board which was a Lien Chang LI-2190 ... it seems that common problems with this type of board are bad solder joints due to the temp. cycling, or blown capacitors, but I was too lazy to resolder everything so I just disconnected the BL signal line that goes between the main board and the inverter board, and this solved the problem. In my display it was a green line, marked BL on the inverter board -- I removed it from the connector and just taped it off. I'm guessing that this is a blanking signal that the invertor uses to signal to the main board there is an overcurrent situation and that the display should be blanked/shutdown.
I'm certain that there are still problems with the inverter and it might go again, but at least I have a working monitor for the time being.
Caveat emptor.

You have to install the nec driver for this monitor. I have the same monitor. Im looking for the driver now. There are 2 versions of this monitor with the same model # . You will need to find the driver to the touchscreen model.

Look for bad caps with bulging top in the power supply first, post back what you see inside so we can guide you further, see example of failed monitors due to bad caps (after about 2 years): http://s807.photobucket.com/home/budm/allalbums

Sorry to say, but I'm having the same problem. If it doesn't change when you press the Fn key and the hollow/right arrow sunshine, then, I doubt there's anything you can do.

Restart your computer.
As soon as it starts the start-up process, keep tapping the F8 key, repeatedly.
When you see the Windows "start-up" menu, select "start in safe mode".
Does your monitor work in this low-resolution (640-by-480 or 800-by-600) mode?
If so, then you had configured Windows to a too-high resolution that the NEC did not support.
Choose 1024-by-768, and click "Apply", to test that the NEC supports this mode.
Try connecting the NEC to some other computer, to see if the NEC itself is the problem.
