Touch screen no working on Xperia Z

[suec67]

Hi all, can anybody help please, the touch screen is not working on daughters Xperia Z. Loads ok & can power off using the volume + key & power button & then turns on but touch screen still not working, It hasn't been dropped & no liquid spilt on it, only 2 months old. Can't download anything support etc from Sony as it asks to enter the password to open the phone which she can't do as the touch screen not working.

Is there another way or does it need to go back to the comapny for repair. It is contarct with Virgin

Thanks in advance
