My friend dropped his iphone 3gs like a couple weeks ago in the toilet (was before he did his business) and now his backlight is out. His phone is completely dry and everything works fine minus the backlight. Water sensors have been tripped, he's out of warranty as well with apple even though i know they wont cover such a thing. I tried messing with the settings with the flickering to attempt to turn it on, hard resets a few times, and nothing seems to work. i did a lot of research online, but the only thing that i see is that he might have to replace that spring coil but that requires expert soldering skills or paying a guy around 150 to 200 to do it. Any advice on what can be done? Can I buy a new board for the 3gs? I don't need a new digitizer.
