Hi and welcome. Look inside the battery compartment to see if there is any 'green' deposits where the batteries make contact with the terminals, if there is then you will need some fine grade 'wet and dry' paper to remove it. After cleaning, and the new batteries give the same result, the I'm afraid that as Wave says, it could be an internal problem meaning another camera is required. All the best.
