Hi,

You may have to dis-assemble the camera a bit to check that the corrosion has not gone further than the battery terminals. It may have affected the cable/wiring connections on the back of the terminals themselves.

Here is a link to the Ifixit guides for your camera. The guides will help in the dis-assembly process.
