For the last two weeks, my D600 will intermittently and suddenly lose power. The top screen goes blank for anywhere from a few seconds to several minutes. It does not seem to be related to actual battery power (and indeed has happened on a full battery almost every time), and changing the battery does not fix it. Some shoots it does not happen at all, other times it will happen several times. It has happened while using triggers for off camera flash, but it has also happened while shooting strictly natural light. It has happened with my 70-200 f2.8 and 24-70 f2.8, which are the lenses I use primarily.
Googling brought me information about "Dead Battery Syndrome" in the D300, and this does sound like the same problem, though I have not read other accounts of this happening with the D600. I have tried cleaning the lens and batter contacts with Deoxit, re-updating the firmware (though it was already current when this started), turning off the VR on the 70-200. I added a battery grip. Nothing seems to work consistently.
I'm somewhat reluctant to send it to Nikon with this intermittent problem. I'm thinking they are swamped with the current recall, may not be able to reproduce the issue, then I'm out the fee for shipping and evaluation. I will eventually if I can't fix the problem any other way.
Anyone who has a similar problem, or any other thoughts?
I had a similar issue with my D300s when I added a battery grip to it. The camera had the symptom where all power would be lost, or the camera would do a reset at random times.
I eventually tracked it down to incompatible batteries. I had one Nikon battery rated at 1500mAh, and a generic battery rated at 1800mAh. The moment I replaced the 1800mAh battery with another rated at 1500mAh, the problem went away.
This may not be your exact problem but it may provide you with a clue?
Thank you for the thoughts. I did do a hard reset when this started, and I do exclusively use Nikon batteries. I did not use a battery grip until this started (was hoping it would help.) Perhaps it WOULD be useful to get two new batteries and see if that's the problem.
Of course the camera is working perfectly today. I did another round of contact cleaning/conditioning. It chose to act up yesterday in the middle of a paid shoot, and I have one tomorrow as well. Guess I will have the D90 prepped to back up if necessary.
Does your whole camera lose power or just the top LCD. If just your top LCD is it completely blank or is there an error message. I had a similar problem and it turned out to be a corrupted memory card. Next time it happens, try swapping your cards and see if it fixes it.
The top LCD is blank, no lights, can't focus, so I believe it's the whole camera. The corrupted memory card idea is interesting. The card is relatively new, a Sandisk Extreme Pro high capacity card, backed up by a slightly lower capacity Extreme Pro card. I do always format the cards prior to use.
You might be surprised. When my memory card was corrupted sometimes the lcd was blank, sometimes an error. The rest of the camera still showed as 'on' but I couldn't focus either. Turns out my primary card was fine, my back up was not. Even with one good card, so long as the back up card was in the body I couldn't fire, focus, or anything. Sometimes the camera would be fine after a minute or so. Once I found the cause I just got rid of the card. It was only happening randomly and was very annoying. Worth a shot anyway.
Cant find it now but somewhere I read about defective memory card and or battery grip causing that problem.
If you send it to Nikon for the shutter Recall which is free including shipping, considering that replacing the shutter is a major surgery, and all the other D600 problems, I would assume that Nikon has to thoroughly test the camera after replacement, I would also assume this now being a computerized device that the test is done by a computer which tests every thing and your problem would show up on the test results. Why not send it in to the D600 convention with its other friends.

Update: made it through 3 hour shoot, 200-ish shots, used two off camera flashes with triggers: no power loss. Whether it was the extra contact cleaning/conditioning, the change of memory card, or the extra shiv I stuck in the battery compartment, I don't know.
I do think I will send it in mid-April, regardless, once I get through a few commitments.
Update to the update: the day after the trouble free session, the camera went insane while taking photos on a hike. Power went on and off randomly for a time, then , new development: ERR message. Long story short, I'm just sending it in.
