Xperia SP only charging when off (=not charging)

[kaminwurze]

Hi,
yesterday, my phone got a little wet on the back, but it kept working fine the whole day. In the evening i plugged it in, but it would not charge. I put it in rice over night but it didn't seem to help...
When i plug it in (switched off) it seems to charge (at least the red light is glowing) and then it powers on on its own. It seems that it then stops charging, and as soon as it has powered up, it switches off again because the battery is empty... And the cycle starts again.

I already tried different cables and chargers, but no luck...

Can someone please help me?

It doesn't charge at all with the Sony wall charger and Sony's usb cable? you might want to take it to a Sony repair center

Well it did charge, but only when it was off (and it immediately switched on automatically).

But I guess I've solved the problem now! Turns out it was still a little wet inside the USB plug. I blew in with the hairdryer for about 15 mins and now it is charging again!
