In the exciting third quarter of a high school football game (9/21/12) my two-year old D700 totally shut down. One minute it was capturing action on the field (as well as the stands), the next minute there was total darkness. By the next morning the camera was packaged up, postage affixed and mailed to the warranty provider, Mack Camera in NJ. Having dealt with them before, I knew they would take all the necessary steps to diagnose, repair and get my trusty sidekick back to me with due diligence. I'm sure they tried hard but they ended up sending the D700 to Nikon with no further news as to the problem. Nor was there an estimate on the completion date. To make a long story short, the camera - in all its repaired glory - arrived today (10/22/12) I do count myself fortunate to have it back in a total of four weeks time. What I do not understand very well is the work that was completed. "Replaced rubber grip. Replaced rewind side rubber. Replaced CF cardholder rubber. REPLACED POWER PCB. Cleaned CCD. General check and clean." I get it all except the 'power PCB' thing. Any colleagues have some input for me on what that is/means & any consequences I might be facing because of its replacement? Just a little sidebar to this drama. I had a wedding to shoot on 10/13/12. Knowing the D700 would not be back I ended up buying another one as my main camera for the wedding with my D300 as the backup. It looks like the D300 will soon be on the selling block and I am punch-drunk happy to have two D700s.
