3Gs earpiece does not work, proximity sensor works.
The proximity sensor works.
The speaker works.
The headphones work.
Everything else works fine.
I took it to a local repairman and he tried a replacement earpiece but could not get it to work and told me that he thinks the problem was the connection at the logic board or software.
I've researched since, an it seems to be pointing to the #3 connector ribbon but I am puzzled by the proximity sensor still functioning.
I'm a newb and need some input from someone with experience.
Is this a good question?
