Blank screen after water damage
My iphone 3g dropped in water, i shut it off ,opened it,cleared excess water and put it in the rice bag for 2 days, after that I checked to find it was turning on but half of the screen was unresponsive but I can see apps and half of the screen was working fine .So i again put it in rice for 4 days, now screen is totally blank , only receiving calls no back light or any lines simply black screen . I tried home and sleep/ wake button reboot , but its not working either.
Please help!!! thanks in advance
iPhone 3G, iOS 4.3
