Xperia –Ray display problem

[kumar_mohanraj]

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?

you have to give it to the service center...

it's a hardware issue NOT a software one.

Thanks for ur update. Problem in phone is same as shown in the video. But if you turn on the power button after 3 to 4 hrs the screen turns on normally. Once I locked the phone, then it need to remove the batter, and restart to open the screen or I have to wait for long time to see the screen by power button.

I will be giving my phone to service center.

Yes. Its a hardware problem. Just two weeks
before I received my phone from service after replacing the hardware. Its
working absolutely okay.

[ajinkya1]

they replace the phone or a part of hardware??

[Uliwooly]

most likely just the LCD as it's cheaper to do so than replacing the phone

[kumar_mohanraj]

They replace part only...

Do you know if the problem is with the display or the motherboard? I'm having the same issue and I have no warranty so I wanted to buy a new lcd display and change it but I'm afraid this won't solve the problem.
