I just replaced my lcd on my iphone 3G. It was working fine until I dropped it. Now the screen is black. I can hear it charge and get incoming e-mails but I can't see anything. Could it be my lcd again?

Hi,from the problem you are experiencing it's obvious that the problem is from the lcd screen,the shock it sustained when it dropped is responsible for the damage on the lcd screen again.
The solution is to replace the lcd screen but you have to be more careful with the phone,the iphone is a very fragile phone which should be handled with extra care,if the screen is replaced and you mistakenly drop it again,i'm sorry,you will have no choice but to keep replacing the screen,which is not good enough for you economically and also for the efficiency of the pone.

Thanks and take care
