Nikon D5100 Error, release shutter button again when pressing life mode button?

I've searched over the whole google, the problem is that the mirror is stuck? So the live mode can't be launched. The camera shoots photos like always, but i can't launch live mode due to this error. I have not a clue, i removed the lens, nothing is broken but i can't enter live mode. This issue appeared all of sudden without reason and while i've found that its only some par ts that must be moved, i can't be sure what should i do. Heading to Nikon is not an option for me as i'm not into paying a bunch of money to them for something that many people fixed on the web. Whoever knows what is that error and can help me without telling me accusations that i don't wanna pay is welcome.

""all of a sudden without reason" - LOL.

Perhaps it has something to do with when you dropped your camera on the floor

You really are a donut, aren't you?!

Look, your camera is broken. It's entirely your own fault. Either get it repaired OR buy another one, next time don't drop it. Use your common sense.

I was getting the same error on my Nikon D5100. I had to sent it to repair.
