It looks as though I am going to have to send my D700 to a repair facility for the repair of the hot shoe. I have tried the suggestions that I read about on the forum and nothing worked.Neither my SB900 nor SB910 will fire when mounted to the camera. Strangely, my SB600 will fire. My question is who do you recommend sending it to. I live near Dallas, but the list of Niikon authorized repair centers does not include any in the area. I would like to send it to a repair center that is recommended by some fellow Nikonians. Thank you for your help, Mike.
