Defective lcd screen

[Kfcman69]

Dear sony
I have had my z1 for a few months now and I turned it off but then when I pressed the on button to turn it back on. It wouldn't turn on. I heard the noise of it turning on and saw the back light but no colour. Then I turned it off and on again to see if that would fix the problem. As a result no back light came on. Am I still under the warranty to get a new phone or an new screen at least?
