Sounds like you might have a looose wire somewhere. I've had problems with putting in a fresh battery and the camera not even turning on! Wiggled the positive wire and then it worked. I assume since you only said 'battery' that this is one of the 9 volt battery Moultrie's and not the 6 D cell model. I have had good luck with the repair dept at Moultrie so if you can't figure it out...send it back!!! Anyway...best of luck!
