Hi everyone- I just took out my D70 to take some shots, and while the AF is working, the flash is firing, the image is not coming up in the LCD, nor is the counter number changing. I changed memory cards, thinking that it was defective, but the camera is doing this with other cards, too. Is there a quick fix or (sigh), does it have to go in for repair? I'm no longer under warranty, and I'm wondering if this is a sign that I should upgrade. Thanks in advance to everyone for their help and advice.
