3310 very low ringing volume


Buzzer is ok.

Buzzer pad to vb is good.
Buzzer pad to N400 is good.

Replaced already N400.

Anyone experienced this too? Any tips please. Thanks

Thanks Willy. I measured from CPU buzzer PWM to N400 Pin 3 not 0 ohms. Difficult to jumper to CPU test marks, as the sides where covered with epoxy. Anyway 3310 not worth changing CPU... I'll just keep this for spares.=)
