Screen Blank After Making Call on Xperia C3

Hello, I am Andika from Indonesia.
I got problem with my Sony Xperia C3.

First, I made a call with my friend. Suddenly, the screen turned black, but notification and LED notification is still active. I tried to force restart the phone, it shows SONY and XPERIA. After that, it turns blank again. What must I do?

Welcome to Android Central! When the screen went blank after rebooting, could you tell if the phone itself was still powered on, or did it actually shut down again?
