Check to see if the board has dry joints in the solder?

Just use a soldering iron and reflow all the points...

GOOD LUCK... :o :o :o

first of all it would be cool if you could post in the right section "Nokia Hardware Repair" for this question!

So your ringer lines come out of the UEM and through two Inductors "L182 & L183" and straight to the Buzzer Pads on the PCB, there are our Decoupling Capacitors, "C191, C192, C187 & C188", if any of these are shorted then it will stop your buzzer from working.

Component Layouts for you son!

Oh and make sure the ringer is actually ok and doesnt need replaced and make sure the contacts are clean!!
