Let me understand this, when you press the power button the screen doesn't turn off the screen?

Power button act as volume key right, let he do a complete Service test using *#*#7378423#*#* OR Install below software

So you can identify the issue...

Perhaps proper English will let other users understand your issue.

Repair your phone with SUS or PCC if that doesn't work, take it to a Sony repair center.
