Hard Reboot usually fixes up problems like that. Just hold down your power button til the phone reboots itself.

If you're referring to (lock) screen going black and not turning back on...

I had the same issue. I took my phone into the Sprint Repair Center, and they determined I had a bad prox/light sensor. I had a new EVO LTE a couple of days later. 2nd LTE has performed like a champ.
