near the buzzer are 2 tranzistors try to change them. Try to enter service menu on buzzer test and see the volume there. The keypad not working because of intrerupted tracks

try another key - pad on phone and check if buzzer is laying well on board to allow signal flow into board .
clean laying positions of buzzer and key - pad with any of the following such as
1. methylated spirit.
2. thinner
3. petrol
4. sate - wash liqiud .
if you have any of this liquid reagant , this can help you better.

try this now.
couple back , it will work.
