w880 microphone replacement

Would anyone know where I could find a schematic showing how to replace the microphone on the w880 ?

You don't need schematic,it is soldered on the down part of the board and it is like a button 4-5 mm.It is soldered directly to the board(no wires)so you need a blower with hot air to remove it and replace.If you will try to remove it without hot air you will destroy contacts on the board so i suggest you to take it to some repair shop.

Thanks.I might leave it off so.
