Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

If I understand you correctly, the display is black? Have you tried to remove the battery and insert it again? If the problem persist, I suggest that you perform a software repair via PC Companion:
http://www.sonymobile.com/global-en/tools/pc-companion/

In PC Companion you press start on Support Zone > Start on Update the phone/tablet software > Repair phone/tablet (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.

Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.
