Water Damaged, Black Screen, Bing noise on connection,

Hello, I have a phone belonging to my mother which she accidently put in the washing machine for about 10 minutes a couple weeks ago. Nothing shows up on the screen and the only sound the phone makes is a bing about every 2-3 seconds when its connected to a power source.

I tried plugging the phone into my pc in order to get the pictures off of the phone which she asked if it was possible but I cant access them even though the harddrive shows there is saved information on it.

I'm wondering if anyone has any ideas on what could be done to repair this phone or is it possible the whole thing is just fried.

Also I changed the battery but it's still the same.
