3510i transmition sounds in buzzer
 

Have problem, 3510i calling or recieving calls, noisy sounds of transmitter, higher then poliphonic sound. Any solution please.:confused:

check first
is there any jumper made on bord then remove that wire and connect new one and clean bord,
if not then try to flash phone

chq something is shorting between body and pcb clear this all will b ok

Change IHF amp. IC (µBGA)

Thanks for all, nothing helped. I think, something inside board is shortcutted:mad:
