Hi Czoran!

First just check BUzZER if it's unsoldered or damaged, then you can try to change a small transistor named: BBV , it's located between the SIM-Connector ,the CPU and the LT915.

Change it (you can take it from another 2100 board or SGH600 boards) .

Thanks!

I've changed buzzer and bbv, but still nothing. My parts in another phone are working! What else could be? It was not dropped, no force on it, just normal use, and suddenly not ringing.
