Try performing a power reset. There should a power reset button near the charging port. It looks like a tiny hole. While plugged into the charger, use a paperclip to push the button inside this hole for 3-5 seconds. If it turns on, please allow it to charge for 4-6 hours before using it.
Support Troubleshooting Guide

I had the same issue with my kindle fire once usually if you hold down the power button for around 20 or 30 seconds it will turn back on and should work fine if not contact tech support and they can give you more information and hopefully a solution.

Holding down the power button for ten seconds resets the device. After resetting two or three times, be patient because it will definitely load on the third time.

Try pushing the reset button in the TINY hole in the back of the tablet. This will reset it to factory if it works.

I don't have a fix, but I feel a scam since I just got mine today from No More Rack & mine cord doesn't fit either.
