try using repair in sony pc companion one time to see if it fixes it, if it still has a dead acreen then try contacting sony service centre
i solved the issue... byt holding power & volume , then it vibrated 3 times then worked as before, I did a reset of the phone, Havent tryed the phone on gaming after that yet..
But hopefully it was a one time thing :S pc companion ??
