I used my 810 a few days ago and it worked fine, today it doesn't even come on. I've tried 4 batteries with the same result. This sounds like an expensive fix.
Anyone else have this same problem?

Did you rest it to factory settings. I'd go from there. May not work if you can't turn it on though.

Use a wooden pencil eraser to reach down in the battery box and clean the contacts. Use it to clean the battery's contacts too. If you have any corrosion on them that should help to get the camera in touch with the battery again. If you can actually see corrosion on the contacts you might have to be a bit more aggressive on them. I've ground xacto knife blades to get into tight areas to gently scrape the corrosion off. Good luck

A friend had this problem a couple of years ago with his Canon DSLR. You have already changed fully recharged batteries. My next suggestion is to change lenses and see what happens. If that doesn't work, you may have an electrical contact problem with your battery. Worse yet, the internal electrical motherboard is defective. Those are not usually repaired, but exchanged with a new one. I know of one person with a Nikon DSLR who had this issue. And took it to an Authorized Nikon Repair Shop. They are the only repair shops that can get Nikon Repair Parts. Good luck.

White vinegar on a q-tip will also remove any battery corrosion. Here's a link to Nikon's website on performing a two button factory reset. Not sure if it will work if it's not on. https://www.nikonusa.com/en/learn-and-explore/a/tips-and-techniques/using-the-2-button-reset-feature-on-nikon-dslr-cameras.html

Thank you all for your suggestions! I tried all of them and I'm resigned to send it for repairs.
Thanks again.

Take the battery out and push the shutter button to discharge it completely. Insert the battery and see if works. This rarely works but is worth the try.

Thanks Haydon, I'll try it.

Contact Nikon tech support via their website and see if they have a solution for you. They usually get back to me in a day at the most.

Terrible idea - these are plated and the plating is very thin - an eraser is very abrasive and will compromise the plated surface - better to use a liquid contact cleaner, sparingly, of course.

With the power switch off and a good battery inserted, does the green flash-card-read/write light come on when you insert a flash card?

Possibly. Let us know how this turns out.

Make sure you have the camera turn on. Sound silly,but I’m just saying.

Step 1. With a magnifying glass and a strong LED light inspect the terminals of the last battery that had been in the camera. Mine for a Sony has five slots. Look for corrosion crud and condition of the terminal fingers.
Step 2. Do same with the battery compartment. Are all fingers intact and not bent or broken or crudded up.
Step 3. If the above tests pass and a new fully charged battery do not work, then you have an internal camera problem.
