Xperia U will not turn on after battery died

[lolaeden]

Hi,

My daughter was playing Cut The Rope on my phone - my battery died last night and i plugged it in to charge all night - The red light came on but no charging sign.

This morning when i went to turn it on it did nothing. Ive tried everything that has already be advised on this forum. The odd occasion the backlight comes on and thats it.

Tried

- Wall charger, USB Charger, Different charge

- Tried the Charger, Power Button & Volume up button

- Took battery out at least 100 times

- PC companion (didnt recognize)

I found several post about this and no fix?

how do i do that?

[Arnab]

SUS=Sony Update Service.

About the safe mode for Xperias, I think its Power On with volume down, but please be sure using Google.

While powering on the phone press menu button.(You can try tapping ) If the phone vibrates after pressing the button it is successful and a safemode logo will appear on the UI

It worked now it comes on... battery is now at 50% but the phone screen now keeps going blank, with backlights on snf if i press the lock screen button it acts as its locking unlocking etc but nothing on screen

This seems a very weird problem .Try Repairing via SUS/PCC. or perform a factory reset after going in safe mode.

Note:This will remove all the data.
