I have had my D600 for about 2 months now. When I first got it I was having trouble with the rear LCD. After I took a picture, no preview would come up, only the green LED light would come on (near the bottom right of LCD). I took it into Henry's and they suggested it was a memory card issue. I bought new cards and it seemed to fix the problem. Everything was fine until last night. I was out shooting and everything was working fine. When I came inside and sat down I went to review some of my shots. Now the preview button and menu buttons are not working (nothing comes up on the LCD, just black screen). The only way i can get anything on the LCD is when I press live view, and that works as it should (great....).
I am upset that I didn't get a new unit when I took it in the first time (day 2 of the 15 day exchange window), and now I am unsure of what to do or think. Any recommendations?!
