I'm certainly no camera repair expert but that kind of damage may well cost you more to repair than to just replace the camera.

I once had a film camera that got some mist on it from a photo shoot in heavy fog. Camera cost $400, repairs cost $190 and took 6 weeks to get it back again.

It's fortunate that you were able to salvage the memory card though.

Think of it this way, it might be a good excuse to go get a newer model. lol

Good luck.
