There are few things that a person can do for fixing a DSLR camera.
First is always make sure that the battery is charged.
Then try another memory card.
All cameras has a camera reset - that resets the camera to factory settings.
That resolves many problems caused by accidentallyidently setting something that may cause other problems.
Read the User Manual to find the factory reset.
The User Manual usually contains the phone number/email address of the Service Location for that camera.
Hi . . . shutter crapped out on me. (To boot, I borrowed my sister's D50 and a similar thing happened!).
I took it to a store but didn't have the battery with me; the guy told me to put it in P mode, then press the shutter button for about 10 seconds, then remove the lens and install it again, then deactivate the shutter button.
It doesn't seem to be resetting my shutter, which probably means I need to send it out. However, I looked online for Nikon's recommended procedure to handle this and I could find nothing.
Anyone out there in Cyberspace can confirm or deny before I send my camera out? Thanks!
