There are authorized service centers here but Nikon has been lax in providing them with the equipment and training required to repair newer gear. When I needed to send my D5 in for repair out of warranty I called more than one "Authorized Service Center" from the Nikon USA website and all said the same thing, they couldn't work on it I had to send it to Nikon. Nikon USA has actually out-sourced most of the repairs to vendors they choose and it appears that part of the deal is that these places only work for Nikon USA and can't take in work directly from the public. Nikon Melville repairs now get sent to a location a town over. If you want to drop stuff in person, you have to drop it at Melville and they run it over to the repair center. Previous gear I sent to Melville came back from this other location and a different one in the Bronx. The Bronx outfit had a name I would not have associated with Nikon.
