My xperia u fell n the screen got damaged due to it.But the touch was alright and it kept working till evening.Only after I went for factory reset that it didn't turn on.By trying all kind of ways I tried to turn it on but everything went in vain.That may be the technical problem according to you?
Connect your phone to a wall charger > press and hold power & volume up for 10 seconds > let it charge for 2-3 hours
You can try to remove the battery and SIM for a while. Put it back and connect the charger and let it be connected for an hour or more. Then try to start the phone as usual.
