I searched and all I found was another thread that no one responded to. Working on a 3GS and the ear speaker wasn't working nor was the lcd. So to fix the lcd first I replaced with another screen assembly I had laying around. LCD began working, now even with this extra screen assembly on my speaker isn't working. I know this speaker worked on the other phone it was on previously. So what ever sends the signal to the speaker on the board I believe isn't working. Phone has never been wet and all water sensors are still white. Guy said speaker just quit working. Thanks in advance for any help.
