To cut to the chase, here is my problem: (1) D80, 1.5 yr old. (2) Recently, AF-area mode malfunctioning: a. In M, A, S, P mode, when "AF" button is pressed on the top LCD to switch between "AF-A, AF-S, AF-C" none worked and it stayed as "AS-S" on the top LCD b. Try to change the setting in CSM, menu#2 (for AF-area mode) it is grayed out without access. c. Odd enough, when the mode is set to "sport," the default setting as AF-C is shown on CSM, menu #2, but still as AF-S on top LCD. d. Called Nikon services, did a lot of things such as, switch lenses, hard reboot etc. None worked. Did anyone had this experience before and how did you solve it? Your help and suggestions are appreciated!
