When i take a pic,it says error press shutter release button again

SOURCE: nikon d40

I had exactly the same problem, i tried everything,battery out, sd card out , lens off etc...nothing worked.Completely by chance and irritation i repeatedly pressed the shutter butten over and over
( without the lens attached ) till it didn't react at all.On my LCD i got a normal menu so i put the lens on and bingo it was fixed, still works fine.I think maybe the shutter was out of alignment.
Hope this works for you.

same thing has happened to me, only bottom half of the picture displayed and same message comes up. It looks like my best bet is to talk to Nikon about it. Thank you.

SOURCE: Error. Press shuter release button again

I was taking pictures, then when I pressed the shutter release button, it took a long time. Then the error message came up. I tried pressing the shutter release button again, nothing happens. Still the error message. Please help me

The manual (pg 112) simply, and unfortunately, states this message "Press shutter release button again. If error persists, consult with Nikon-authorized service representative".

Some questions that might help: have you had the camera in some extreme conditions, damp, sand, etc. Clean the shutter button really well. Maybe use a small air blower and clean in the shutter release creases.

In the end, if the error continues, it will need to be serviced.
