Blinking light

[Linda123]

Hello, 

Yesterday I put my phone on the original charger. It stayed there over night. Today morning the light is blinking red and nothing works. Display is black. Nothing from other support sites worked yet. Is the battery dead? I dont know. The xperia companion doesn't work as well  .

Did you try pressing and holding both Power and Volume up buttons for at least 7 seconds? This should force a restart.

Yes, I did. But no response. After that I tried the Xperia Companion. Still nothing. Now I am going to send it for repair to Sony. No other options left.
