Hi all, I have an Xperia ARC S and it's about some weeks that when it becomes hot (very hot) the display become black. The touchscreen works, I hear the sound of touched icons but I see nothing. I sent it to the sony assistance but the gave me backe the phone with a "nothing found" message. I made an hard reset, but nothing. I suspect it has to do with temperature because if I refresh the phone the display come back. What do you suggest ? Until some weeks ago it all worked fine... TIA
