I bought my Xperia ray six months back. Updated my phone software to ICS on last month. It was working absolutely fine after ICS update. From last five day i am facing the problem in display. When I trying to unlock my phone through power button or home button just backlight turning on, but the screen remain blank (black). If I turn on my phone after keep my phone idle for 3-4hrs, then it shows unlock bar screen without any problem. Due to that I could not able use my phone now.
Still i can able to attend my call by connecting through headset. But I could not able see the caller ID, it remains blank.
I tried to resolve this issue by doing factory reset, and software repair through PC companion. But I could not solve the problem. Can anyone help me to resolve this issue?
?
