[Q] Can't see anything., screen is completely black. topic

So I have an XT1064 that I just updated to lollipop 5.0.1 (22.21.25 build ). Phone is completely stock,. Anyways I was messing around with the settings and I was adjusting the screen brightness. I lowered it to the lowest setting and the screen turned completely black. Can't see anything. I already tried rebooting the phone but as soon as it boots the screen turns black. Any ideas on how to fix it.
