If you were adventurous you could take the camera apart and just replace the caps and it should boot up good as new, otherwise you might as well just buy a new one since they're apparently cheap.

As one final test before you chuck it, use a multimeter between the camera's power and gnd connection and make sure there is voltage getting to the camera. If not it could just be a loose/open connection somewhere.
