Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm sorry to hear that your Nikon camera is not working right, and I'd like to provide advice that will help with the problem if possible.This problem can happen for various reasons, in my experience. There are various things to try, and what else to suggest depends upon some specifics, asked about below:
A. How old is the camera? in months or years since you bought it.
B. How long has the battery or batteries in the camera been in-use?
C. Has the camera been dropped or otherwise subjected to mechanical shock(s) in its lifetime?
D. Has the camera been operated in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ?
E. Has it ever been subjected to a humidity higher than 85 % or gotten wet ?
F. Has the camera been operated in a gritty or sandy environment, such as a beach, a seaside, a construction site, or the like?
Thank you for the ready response with the information I requested.
At 2 years, the camera is out of warranty, first.
It is good to know that the camera has been cared for, but being splashed with water could have affected it.
The new battery put into it, was it charged up thoroughly? a rechargeable battery that is new, should be given an initial 6 hours on the charger, before first use, owing to its having sat of a shelf unused for a while.
Try 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.
Then try cleaning the terminals in the battery compartment, after removing the batteries, first by rubbing off with a fresh pencil eraser, then by wiping the terminals off with cotton swabs moistened in rubbing alcohol, then letting them dry off for 5+ minutes with the battery compartment door open, then try turning the camera On again.
Let me know the results of those things-to-try, if you would, by and by when they are done, please.
