Hi guys, i m having an xperia u running ics. it fell from my hands and froze so i took the battery out to restart, since then i cant turn on my phone when i press the power button it just vibrates once an there is backlight on the screen but nothing else not even the sony logo. Sometimes the illumination bar flashes green. i tried everything from removing the battery several times to flashing. the flashing proccess completes with no errors but the problem is still there. Any ideas? i have no custom roms or so only rooted with flashtools...

It seems the screen was broken take it to any nearby center to repair its hardware

Thank you for your answer, but i m pretty sure that the screen is not damaged maybe motherboard, although i would like to be sure that there is no software problem if possible... from what i have read when the sony logo doesnt appear means that the kernel is dammaged... is there any way to flash xperia u stock kernel first and then flash the firmware? also i had asked sony to give me the code to unlock the bootloader, but i never used it and didnt unlocked it, have i lost my warranty only for asking for the code?

Your warranty is still valid. I suspect your motherboard is damaged. But since u dropped it means warranty is gone

Finally, the problem was the screen and the touchpad, they changed both at the service point under warranty, as they had no obvious damage i guess... is this a common problem with st25?
