Hi @splashmit

Firstly, your question is very vague. This means that I (And many others) don't know what you've tried. So in no particular order can you please update your post with the following:

What occurred beforehand

What events followed

Had any previous events led up to this?

Had there been any previous incidents?

What troubleshooting steps have you tried?

Have you tried ipa, or other chemicals?

Have you taken apart this device

Have you tried reassembling (To which no avail?)?

What i can roughly say though is that there is a possibility that some dirt has gotten in and jammed something, but I am unable to know for sure unless the above questions can be answered to help with diagnosis.

@splashmit you can find a really good writeup about the issues with the stuck mirror on the Nikon D model cameras on here (link repaired on 10/18/26) When you do your repair, take plenty of pictures and create a guide for the rest of us. It'll help the next person that has the same issue with their camera. Create a new Guide - iFixit

The link in “on here” appears to be stale. It goes to a site providing e-signature services. Please check.

Dead link. Words are hard I guess so here’s a random block of text to exceed the minimum character count.

Thanks a lot. I did the repair thanks to a very old YouTube video but… the gear broke again. Thanks again for the answer.
