i know i know everyone has asked these questions but i havnt found one to fix my phone yet. i have managed to teach myself how to open my phone and check all my cables. so with that said heres my situation.

i dropped my phone on a tile floor on the one day it wasnt in its hard case so im a little ticked off with myself. but the screen flashed between black and white about 3 times and then it just went black. Now, there is power to the phone but the screen is black only! i have tried pushing the home and power button for 10 seconds and while connected to the computer it clearly resets but no action on the screen. i have also disconnected the power completely before messing with anything and it connects fine to my itunes so please please tell me there is some answer i can get to what the issue is before i take it into apple.

thanks!
