Mine too. SDcard locked. Now the display is blank every time I swap out the memory card. I could turn it off and then back on and it would be fine but now im only getting a few pictures or none at all.
I brought the cam home and set it up at the back door. within 1 day I could see the display was starting to fade out, by the 3rd day it was blank again. guess i'll send it back to Moultrie.
It was a good game cam. ran 24/7 for a year and half.
