J I N X,
Thank you for using the Dell Community Forum.
Here are some things to try and resolve the issue with the monitor.
I'm experiencing the same problem/defect with a newly arrived 1703FPt. The power LED seems to properly function; I get a quick flash of signal when booting, then drops to black.
The OSD menus don't appear. The self-test graphic doesn't appear.
Is there some magic reset hardware button combination? Can't use the factory reset command if I can't see the OSD.
