Hello,My new Nikon says write protected when I tur it on and have tried two other cards. What can I do to remove write protected when I tur the camera on?
If you are satisfied the problem is with the camera not the memory cards, I would suggest starting by finding the menu item for resetting everything to defaults.
If that doesn't help, perhaps remove the battery and leave overnight, make sure you have a fresh/fully charged battery, start the camera and see.
