HI Master's

One Nokia 5233 Box Microphone not working all?

I have already changed 2 Pcs. of good microphone but no result.

Out of 4 pin's, 2 nos. of pin on the right side are showing ground connection and out of two pin's on the left hand side, the upper left corner pin showing no resistance at all?

I have already picked up the small power ic and reballed it perfectly but no joy for me?

Can anyone have the solution of 5233 Mircophon schematics or still picture sort of thing?

Awaiting for the correct solution?

Thanks in advance.

Hi,

I have checked the track , all are ok. No short is there ?

Should I Re-ball the big IC now ?

Right hand 2 pad's are giving short sound? Whereas only one ground should be there ?
