Sony xperia U dead logo comes up but doesnt work?

[saphiroth1]

My sony xperia never died on me until yesterday.  When I woke up, my phone wouldn't turn on so I went and charged it.  I waited 2 hours and no results.  I looked on these forums and saw that people took out the battery for 10 minutes first.  I did this and when I put the battery in I put the phone on charge..  After having it on charge the sony logo appeared after a minute, but suddenly disappeared.  This happened two more times, but the phone will not turn on.  Can anyone help me?
