No sound in loud speaker
I have a problem with my phone C6603, don't play any sounds on loud speaker.
I change a speaker and a flex cable and nothing, in earspekers i have a sound.
I change a mother board from other Xperia Z and sound works. Does anybody have a service manual or now how to repair this? It's definitly hardware problems, i flash every possible firmware and nothing change.
Sorry for bad English.
