can't Turn on my xperia T2 Ultra dual

[187]

'i bought a Sony Xperia T2 Smart phone before one month

today while listening to music the phone suddenly switched off - it was charged - then i tried to re- switch it on but it didn't work

tried to open it using the power button and the up volume button or using the "OFF" button - beside the SIM card - but also didn't work

i connected to a charger it gives me the red light - means it charging !!!!! - connected to a laptop , the laptop make that sound saying that some device is connected but it can't read my phone's file. 

i can't understand what happened and what can i do ! ''

Can any one Help me 

is this the Sudden Death ! 

if so, is there  a solution ?

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.

Did you try the repair function (where the phone should be turned off) or just the normal connect in PC Companion?

Sure thing.

Open up PC Companion > Support Zone > Update phone/tablet software > Repair phone/table software.

Leave the phone in the charger for a while just to be sure.
