Question U20A Sony xperia no bell and plays bass?


I took some U20A Sony xperia Mini with low ringer problem, and realized that her neighbor has two components that warmed, and changed the bell still went down, then one of two devices stopped playing, I wonder if you have any way of finding out jumper and repair if you have any scheme to try to identify these components to solve the problem.

I am very grateful for the assistance of colleagues!

Question

I test now and not enough voltage at the buzzer two connectors on the board, but not a sound comes out. It may be some of the audio amplifier board that must have burned?

Below the photo of the nameplate of the appliance Sony U20a.
