Dell Venue 11 Pro - Blank Screen

Hello, any one out there have an idea on how I can fix a Dell Venue 11 Pro tablet that the screen is blank. The table turns on (i think) it does the little vibrate when you press the power button. After a few seconds it will vibrate when you press the Windows Button on the bottom of the tablet, but there is no screen display. I tried connecting to a dock so I could use an external display, but no luck. Any suggestions????
