Sony Xperia Z - black screen, switched on but stuck on constant vibrate

Hi, hoping someone can help!!

 

While using an app last night my Sony Xperia Z froze for about 30 seconds before the screen went black. Usually the phone just restarts itself and goes back to normal, however the screen was black and the phone was still switched on. The usual reset method does not work.

 

I had someone call the phone to see if this would kickstart it back into action but this just meant that the phone got stuck on vibrate for over 4hrs. I left the phone to power down overnight but when I've come to it this morning it is still active - when I press the power button the red LED light double flashes repeatedly. Can't put it into safe mode as the screen is still completely black.

 

Does anyone know what has happened or how to fix this??

 

Thank you!

I agree, repeair your phone with PCC

 

if your phone keep restarting > remove both SIM and SD cards > connect the phone to a wall charger > press and hold power & volume up for 10 seconds > let it charge for 2 to 3 hours then repair it with PCC 

 

 

For future reference

Jenn,follow these steps to repair with PCC before sending it into repair:

 

Performing 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 PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
