Sony Xperia Z - Blue loading line on the screen

[genc]

Hello to all, Please Help

I turned off my phone and tried to turnd on again, but it wont start, i tried all the ways power button volume up volume down, still same issue.

1. When i try to start the phone, it will come SONY logo then screen will go black. And you will see blue line, it will keep doing like is updating or loading something, also on the middle of the screen  you can see the settings icon ( the icon is not the same color like the one that is on application ) this one is black and white.

Thank you for the help
