My D5100 won’t fire and displays ‘Error: Press shutter button’. Help!

Chris says… You probably need to send your camera to an authorised repair centre. The message generally indicates the shutter mechanism is stuck. However, it is worth having a look for solutions online. We found this at Nikonites.com:

“I just had a similar problem on my D5100… The lower-right corner of the mirror was binding with the stop. We were able to GENTLY pry the corner of the mirror away from the stop (from the right) and now it is functioning flawlessly.”

It sounds a risky DIY repair, but the solution had worked for three different people with the problem.
