Question Need help for Xperia V

I just got myself an Xperia V and the first thing I noticed is that the phone isn't recognized by any PC when it's turned on(Fastboot & Flashmode work), also the phone won't charge when it's turned on, accelerometer & gyroscope also don't work. Is it possible that water got in the phone(I never did put it in water). I tried repairing it using PC Companion, nothing changed

Pleaseee help
