The viewfinder goes black

I tried the S setting but nothing is shown in the viewfinder except a few red lines and numbers. I switched to Live view and can take photos using the display on the back. There seems to be something loose when it is shaken slightly. It is almost as though something has become unplugged under the flash.

Update (10/18/2021)

It show the red numbers at the bottom and a red sectional graph and the red focus point but no image.

As you can see the viewfinder information that tells us the finder shutter is not closed (broken).

This sounds like your reflex mirror linkage broke so the mirror is not going back down to the 45º angle. And with the rattling there could be either a screw floating around or the link arm has snapped.

You’ll need to grab the Nikon D800 repair manual if you are going to try to fix this on your own. I’ll warn you this is a very delicate repair as you will need to take the camera almost completely apart. Unless you have the skills to work on small fragile parts and have micro-soldering skills I would recommend you find someone with the needed deeper skills a local camera repair person or shipping it off to Nikon for repair.

Ok I intend sending it to Nikon for repair. Any ballpark of cost of repair from them?

$100 to $300?

Thanks for the swift reply.


@belrick1 - I would say it should be less than $300


Thanks Dan at least I have some idea or guesstimate.
