Hello,
I Have Sony Xperia Z3 which i tried it into a water for 10 seconds. After 10 seconds in water i found out that the touch isn't working but the screen still works, so i dried the phone and left it on table. (THE INDICATORS WERE WHITE) Later i tried to restart it and the screen went black. I had the phone in rice for almost a week and i tried to connect it with my PC and i reinstalled the system using PC Companion, but i still couldn't fix the screen. Somehow the touch became responsive but the screen was still black, so i was able to call, answer to calls etc using my pc (i was making screenshots and i was openning them from pc so i could knew in what menu am i on the phone).

After 1 week from the incident i brought the phone in a authorized sony service where they told me that the motherboard and screen should be replaced. I didn't accept that and i brought the phone to another private service.
So my question is: Is it possible to be motherboard problem if i can call/answer calls and do all things a phone can do except to see the screen (completely black with responsive touch) ?
