My Nikon D7000 had this "err" message when I made a mistake of moving the camera from a very cold outdoor (-30 degC) into a warm humid room. Immediately the camera displayed the err message, the mirror stay in up position after taking a photo, no photo recorded, it's all black. Pressing the release button again would return the mirror to normal position.

Since then I have removed the back of the camera and dry it with hair dryer, dry under the sun etc... The camera has been working again on and off for a year, but now it is not working any more doesn't matter what I did. I open the camera all the way to the shutter assembly (did not remove it because it looks very good). There's no apparent humidity inside the camera anymore.

For troubleshooting below are what I tried:

- Good CF card

- Full charge battery (I have a backup battery too)

- Clean contact, try with different lense

- Live view work, just won't take any photo

- Auto focus, flash and all other functions work.

- I slight press the release shutter button to have the autofocus on, then pressing the "Aperture view" button after setting aperture to 22 in aperture mode, and I can see in the view finder that the image is dimmer as it should, meaning the aperture control unit still works?

- Mirror lock up for sensor cleaning works

- When taking the photo, I can hear the shutter fires and closes, except that the mirror is stuck in up position. No image save (or it's all black).

What do you think is the damaged parts here? Shutter assembly? Main board, or Aperture control unit?

Any suggestion appreciated!

Updated, in case anyone is reading. Main board changed, exact same thing happened. My next target is the aperture control unit. This unit failed a lot in the D80, could it happen on the D7000 too?

Got the parts already through AliExpress, but can't get the dial off.

Do you know how I can fix it?

If I dont get the inner ring on correctly I believe the pins will short out.

I have a problem with my Nikon D7000. When I turn on the camera, the eye piece view becomes dim. If I take off the lens, I can see the eyeview become bright but when I install the lens the eyeview becomes dim.

I need use high ISO and low shutter speedS to get the correct exposure. But, the ISO that is suitable more than 6400! so what is the problem with my camera and how to fix it.

*sory my bad grammar

The dial (S, A, M, P, etc) has broken and only the axis remains. I can move it and change the function, but I would like to get the rest of the dial to see how it is and make a new dial with a 3d printer. But I have no idea if you have to open the camera or if the dial comes out with pressure.

First of all, my camera "drank" one litre of water, so stop to work. But, i tried to dry, and several days after the LCD show me the "clock" blinking message when i put the battery, and show the battery icon to as the battery is low (but is full charged).

I suppose is dead by water, the circuits and so on, but... this message, i think there may be hope.

Thanks!
