Live View Ends Unexpectedly Or Does Not Start; Shutter-Release Disabled; Shooting (P, S, A, M) - Nikon D7200 User Manual

Live view ends unexpectedly or does not start: Live view may end automatically
to prevent damage to the camera's internal circuits if:
• The ambient temperature is high
• The camera has been used for extended periods in live view or to
record movies
• The camera has been used in continuous release modes for extended
periods
If live view does not start when you press the a button, wait for the
internal circuits to cool and then try again. Note that the camera may
feel warm to the touch, but this does not indicate a malfunction.
Image artifacts appear during live view: "Noise" (randomly-spaced bright
pixels, fog, or lines) and unexpected colors may appear if you zoom in on
the view through the lens (0 38) during live view; in movies, the amount
and distribution of randomly-spaced bright pixels, fog, and bright spots
is affected by frame size and rate (0 166). Randomly-spaced bright
pixels, fog, or bright spots may also arise as a result of increases in the
temperature of the camera's internal circuits during live view; exit live
view when the camera is not in use.
Menu item can not be selected: Some options are not available in all modes.
