Touch Bar Failure - Please help

Hello all, I have a late 2016 13” MacBook Pro with touch bar. The machine functions perfectly, and even passes Apple Hardware Test, however the touch bar is completely dead, as if it’s not there. The power/touch ID button works fine but the screen is black on the touch bar and it does not react to anything I do. I have tried resetting SMC/NVRAM and reinstalling the Operating System with no luck. I bought the machine this way. Any suggestions would be greatly appreciated, thanks!
