Check to see if D501 is short - it's the big diode (in a 3 pin package) that's located just above the test points above the accessory connector.

D501 is ok

i noticed that ringtones and vibration are not working too

i changed U506 as usually it is this chip that is the cause but still the same

thanks for helping

If it was just the ringer fault, then I would suspect U507 (altohough that normally causes complete deadness), but I don't think the vibra motor has anything to do with that.

If you have a spare, you could try changing U507 anyway.
