<p>Thanks guys. I have some more updates. I put the flash in manual mode and confirmed it's not at 1/60. The flash doesn't fire AT ALL in manual mode (though it fires if I hit the flash button). I have tried different power levels and have confirmed that it does change the power levels by hitting the flash button. <br>
TTL mode the flash fires when I take a photo (unlike manual mode which does nothing) but the image is dark. <br>
I took the flash to a store and was led to believe that my having red eye mode on was causing the problem. Unfortunately when I tried to take photos at home I see that the problem still exists. The man who helped me did say that the flash I had worked on his camera, while neither his flash nor my flash would work on my camera body.<br>
So at this point I'm afraid to say that I believe something is wrong with my D700. I've cleaned the hotshoe contacts with alcohol but it made no difference. </p>
<p>I can still return the camera. Any last thoughts before I do so? Thank you again for all of your help!</p>
