Xperia Z1 screen problem

[coxefgun]

It's been 6 weeks I've bought my Z1. Everything is perfect but screen crashes. Whole I use my mobile it suddenly turns screen totally black but the screen light don't turn off. Phone works but screen and buttons don't respond. I have no chance to restart phone. I wait untill the baterry totally decharges and connect my phone to charger and turn it on again. It heppened more than 5 times. I had used Xperia Go before Z1; and it had got the same problem. I don't know what to do. If there's a problem with my screen I think to send phone to guarentee agent.

Give me some advices about what to du plz.

NOTE: I did not updated my software, but rooted.

How can you have the phone for 6 months since it has been released 3 months ago?Are you sure it is Z1?

Well,if you rooted your phone,I cannot help you,it is not my strength.But if you were on official JB,i would tell you repair phone software with sony update service.

It has this problem before I root my phone. So if it will be a problem, I can unroot my phone. That's not problem.

And when I restart my phone (waiting emptying the battery) it solves. Is there any other solve?

So you are not willing to repair using PCC or SUS?It is the last option before taking the phone to a sony service.

I don't know exactly what to do. Would you give me a link about how to repair by this way? I'mreally sick and tired about that issue and bored a lot
