Q: Thunderbolt display not showing desktop

My Thunderbolt display shut down yesterday afternoon while I was working in quickbooks. I purchased this display in January, 2016 and it has occasionally turned itself off and then back on for no apparent reason. This time it just went down. I have taken the following steps and now have a blue screen with no desktop display. When I  check displays on System Information the Thunderbolt Display does appear. I'm stymied. Can anyone help?

1. unplugged and replugged in the display and all other peripherals.

2. Rebooted the computer

I now have a blue screen and the menu bar at the top is showing system preferences while my macbook pro is displaying this Apple Community screen. I have checked system preferences. To my knowledge I have changed nothing since I first set up this system.

System was installed January, 2016.  It is MacBook Pro Retina 15 inch 2015.
