Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
That clicking may be either an actuator that is defectively triggered by 'sick' or 'broken' circuitry... or it might just be, that it is supposed to be actuating, but is having to retry the actuation because something is 'stuck'.
To check that last theory or possibility: Is the camera's behavior defective or lacking in any other respect or manner?
One thing to try is, removing the batteries, and leaving the camera on a (dry, non-humid, non-dusty) shelf for overnight. Then put the batteries back in and try the camera again.
That's different. That may be defective.
But let's double-check: does your model have a pop-up flash? if so, press the flash release button to pop it up. Does it pop up properly?
If so, after it is popped up, try pushing those buttons again - is there any repeated clicking with the flash popped up?
Try the without-battery rest-reset overnight.
Other questions to ask about your camera (I know it is a high-end model for sure):
How old is the camera? in months or years since you bought it.
Has the camera been dropped or otherwise subjected to mechanical shock(s) in its lifetime?
Has the camera been operated in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ?
Has it ever been subjected to a humidity higher than 85 % or gotten wet ?
Has the camera been operated in a gritty or sandy environment, such as a beach, a seaside, a construction site, or the like?
That most probably has a lot to do with the problem!
High humidity may still be inside the camera, on the delicate circuit boards. So I change my recommendation to
One thing to try is, removing the batteries, and leaving the camera on a (warm, dry, non-humid, non-dusty) shelf for several days. Then put the batteries back in and try the camera again.
Such a rest-and-dry-out may be just what your camera urgently needs, to prevent it from becoming a complete ruin. Please undertake that at once! further use of the camera with damp inside it may precipitate further failures or worse failures.
To get back to this case after several days, just go to
I'm concerned about this case and problem, so please let me know, even if all turn out A-OK by and by. Thanks!
(And a rating for my work and my answers - whenever appropriate, whether now or later or when you are sure of the outcome - would be good. Five stars would be appreciated! if and when. Thanks.)
