Xperia Z1 black screen then can't charging!!!

[Kooors]

My Xperia Z1 is one week old. Three days ago, it started black screen several times every day. I have to force shut down and restart the machine.

Yesterday, the screen became black again. This time, it can't restart again. The start screen stuck between SONY and XPERIA several times, then the phone completely dead.

When I try to charge the phone, the phone blinking red light only. Now I can do nothing on it.

What can I do now?

Charge 1 hour doesn't work. Seems the charging with some problems.

 The computer can't recognize the device during connection as well.

Then charge it more,after that try the repair with sony update service.

I'll probably just take the phone back under warranty.Seriously is making my Christmas difficult!
