I searched but couldn't find this topic. When I take a picture with my camera, the viewfinder goes black and none of the buttons work. I can't even power off the camera. The only thing that makes a difference is taking out the battery. I've tried 3 different batteries and 2 SD cards, all the same result. It shoots video fine and it's all good and well until I press the shutter. Every setting has the same effect: seems to take the photo but then I get a blank screen and no response from anything. No zoom, no review, nothing. Has anyone had this problem? I've tried reformatting memory cards, leaving the battery out for an extended period, resetting to factory settings. Nothing has made any difference. I can't find the reciept but I think the warranty has expired. It sucks though because I've taken care of it and it's only a bit over a year old.
Thank you for posting.
