yesterday, Screen of Xperia M dual, started showing vertical and horizontal continuos lines. I tried rebooting. It worked for first.

Then I restored factory settings, it worked for a while.

Then again, from this morning, the screen is completely black and nothing is appearing on the screen.

You may need to perform a software repair using PC companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable.

If this does not help,you have to stop by a sony service.
