I was out shooting today and when my battery got low I switched to a fresh one. As soon as I did that ERR began to flash in the top display on the camera. Switching batteries and lenses did not help. I called Nikon tech support and they had me reset everything with the camera and still no luck. Her best suggestion was that my Transcend memory card was not on their "approved list" and that must be the problem. I tried to explain to her that I have used those cards since I got the camera and was well into this one when the failure occurred. Not to mention the fact that it happened just when I changed the battery and not the card. I can access the menu functions and view pictures on the memory card, but neither live view of the viewfinder work.

(5 minutes later)

After getting this far into my message it occurred to me that the inability to see through the viewfinder might be a mirror issue. I decided to look into the camera with the lens off and noticed that the mirror was stuck in the up position. I simply pushed the shutter button and the mirror popped back down and now the camera works fine. So I am going to change my thread a bit to my impression of Nikon tech support.

Before buying my Nikon D750 I had always been a Canon user. Having called their tech support several times I was very impressed with their level of knowledge. The support staff were actually photographers who knew the cameras inside-out. Shortly after getting the 750 I was in Yosemite and had a problem getting the focus box to move in live view. I finally called Nikon for advice and they had me try a few things to no avail. While on hold with them I notice a switch under the info button that had been moved to L, which apparently locked the position of the focus. I switched it back and lo and behold, no more problem. What amazed me is that the "tech" hadn't been aware of this obvious possibility.

I could tell that the tech today was reading information from a screen as she attempted to solve my current issue. She had me reset the camera and when that did not work, told me to send it in for service. Once again I figured out the problem on my own and was amazed again that the tech didn't think to have me check the mirror. I really like my new Nikon camera and lenses, but am quite dismayed at the lack of knowledge displayed by the Nikon tech staff. Not to mention the fact that Canon support is available on the weekends while Nikon is not. While both Nikon and Canon produce excellent cameras and lenses, Nikon clearly lags far behind in tech support.

So a couple of questions? Should I go ahead and send in the camera to have it checked out or just consider it was a fluke since this has never happened before? I am also unclear on what happens when the camera settings are reset as they had me do. Once I got it back up I can see that all of my settings are still there, exposure adjustment, bracketing, timer, and focus are all still the same. I would have thought that resetting the camera would have wiped those settings. Am I misunderstanding what resetting the camera actually does? Thanks.

Phil, I had a similar problem with an ERR message. I called Nikon, they advised me to send it in. I did. Now here's the good part. When it comes back, it will, or should, have an additional warranty. If you send it in again, before the warranty expires, they'll clean, inspect, adjust, etc. and return the camera, with an additional 6 month warranty. So, sending it in could be a good thing. It might be a minor adjustment, but the rewards far outweigh the consequences of not.

I've been lucky not to have needed any type of telephone tech support for my D750. I don't know how you changed your battery. I know strange things can happen when power is suddenly interrupted, and the electronics are "in use".

I'm sure I may one day swap out a battery without powering-off the camera first. If I do, I will now be sure to add, "press shutter release" to my checklist if I get an "Err" message after the battery change.

I can't help with what the reset does without researching, but, if the camera is working fine now... the service center may have trouble duplicating the problem. If it's under warranty, and you are willing to part with it for a couple of weeks, as Bob says, send it.

I always turn the camera, and other electronics, off before switching batteries. Just and engraved habit.

Well, this thread reminds me of the guy complaining about his printer not working after installing it. Everything was plugged in correctly. The tech went with the guy for about 30 minutes and almost gave up until he asked: Is the printer turned on?

Usually when you deal with someone who SEEM to know they stuff, as you have probably reinforced to the rep, the support can assume you know what the hell you are doing and does not go into settings that should have been already verified by... YOU who implied I know WTH YOU am doing.

Canon apparently does not trust their clients to know what they are doing when Nikon does. THAT is the main difference. Canon is correct and Nikon is wrong. Sad state of affair but then again...

As to getting six months additional warranty... Good idea (Bob).

So you are upset with Nikon because their tech was't psychic???
You talk of buttons on the back of the camera and Don't know their function? Sounds to me like you need to spend some time reading that 500 page owners manual that Nikon gave you when you bought the camera a d learn more about it's buttons and controls.

MT Shooter Loc: Montana

Exactly as the owners manual instruct the owners to do, if they read the manual anyway.

I don't expect psychic, just a Nikon tech to know as much or more than someone who just this year bought their first Nikon camera.

Today you need to be as smart as the camera that you are using. With so many buttons on modern cameras it is very easy to to hit one and not realize you just cause your problem. With limited info the tech has to walk you thru all possibilities to help you find your problem and all the while your are getting more and more upset because he has not cured your problem. That thick book called the User Manual helps you solve a lot of your problems.

After seeing how little of your own thinking you did here, you'd really be in over your head with a Fujifilm disposable!!

If I could turn the calendar back in time, I would opt for Canon and not Nikon. -FiddleMaker

Did you remove the battery with the camera ON? My guess would be yes. As far as resetting and not loosing all your settings, depending on the reset she had you perform. No you won't loose everything. As far as tech support, if your not happy with Nikon tech support, switch back to Canon, apparently you had to use them quite often (What's that tell you?) and really got to know them well.

I own a D750. I have gotten the ERR code twice in 2 years. Generally both times this was corrected after I turned the camera off and then on and pressed the shutter button and the mirror 'unstuck'. Inconvenient. Agreed. Both times occurred after changing lens.
