Powers on, No power to screen
Ok, so my girlfriends iPhone 4 took a swan dive into the salty waters of Puget Sound, and it was completely submerged in the water for the few minutes it took her to get it out. After it was fished out, the camera flash turned on and remained on until I assume the battery died. In the week it took her to get it to me it was in a ziploc with uncooked rice, and I've taken in apart and cleaned it with alcohol and there is very little residue left. Now, when I turn it on, I hear that it's on, and iTunes will recognize it, but the screen won't turn on. It's not just that there is a black screen, because then the backlight would be visible is well, but there's not even that. Is there any hope for this as-is? or am I looking at a screen replacement? BTW, I can hear button presses when trying to unlock it, so the digitizer works, its just the LCD that's not powering on.
Is this a good question?
