The home button doesn't make contact with the motherboard as such...take a look at the top of the dock connector-there are 2 small blobs of solder a little to the left of centre that the prongs make contact with. Try cleaning them.(and the rest of the inside if it is looking water damaged) You also need to clean connector 4 as this connects home button to motherboard. If that doesn't work you may need a new dock connector.
