Tablet is unresponsive

[AC Question]

I have a Verizon 4g lte tablet (according to what it's back says) that won't respond to anything

the power and sound buttons on the top won't do anything and all the screen will let me do is double tap to turn it on and nothing else and it then powers back off like I didn't touch the screen

If someone knows how to fix this please help

Welcome to Android Central! Is it an Ellipsis, or an LG tablet, or some other model? Have you brought it to the Verizon store to ask the reps there? Is it still under warranty?
