U3014, Unresponsive and No Display?

I turned my PC on this morning and after a few seconds the monitor went dark. I purchased the monitor a couple months ago. I am using an nvidia geforce GTX 690 with the latest drivers.

I am connected via display port U3014 to GTX 690. I have daisy chained a U2410 monitor to the U3014 display port out. Both monitors went dark (because the U2410 is connected to the U3014).  I have a second U2410 connected straight to my video card. it still works fine. Both U2410s  work when plugged directly into the video card.

I tried a different display port cable to the PC. Nothing changed. I tried the display port on the video card with another monitor and it worked fine. Windows will not detect display port from the U3014. Windows will detect DVI from U3014 to DVI port on video card, but U3014 menu buttons will no longer bring up the OSD to switch inputs so nothing ever displays on the U3014. I tried to perform the monitor self test (by pressing monitor buttons 1 and 4). Nothing shows up on the screen. It does not even look like the U3014 backlight is turning on. The power LED remains on when plugged in.  I also unplugged all of the video cables from the back of the montior, reconnected the power cord. I can't get anything to display on the U3014 including the OSD. The monitor buttons do not do anything.

Do I need to exchange this monitor? How do I set that up? I am also concerned with getting a refurbished product. I have not had this screen for very long and waited about a year to purchase it so that I would get a brand new A03 monitor from the factory. I don't want to receive a crummy refurbished one with an A03 sticker on it and dead pixels. I have heard horror stories about some of the exchanged units. I am not happy I have spent over $1000 on this monitor and worried about what I will receive if I have to exchange it.

Please help me. The U3014 is a great product when it works correctly. Thanks
