NK 3120 water dropped working except ringtone
 

Hi,

I have 3120 water dropped, service it everythig working fine now but could not here the ring tone,Speaker work fine, Vibrator fine, flashing led fine and it is ok with headset, can it be the N150 adio IC or some PCB error or UEM, can you show me where to directly connecting it to the audio IC, even from the Schema (3100 schema, i think it is same) i could not locate it.

just change the buzzer i/c below the uem (bga 9pin black i/c)
