As of a few nights ago, information remains on the LCD display of my D7000 even after I switch it to "Off". This happens (estimate) 3/5 times, and sometimes will turn completely off (only show me the remaining pictures on my card) after a while. If I hold down the shutter (after doing this), it shows me the remaining pictures in the queue (r41 or so), but will not take a picture. I also cannot browse the menu, but I can change the aperture / shutter. Help? I am afraid this will drain my battery. Only attachment I have had on it was an MB-D11 with the standard En-El15 battery. Thanks!
