70d, Viewfinder blanks out when turned on all shooting mode positions

70d Have tried all positions on shooting mode control, when camera is turned on view finder blanks out. Let camera sit idle and wait 2 minutes view finder clears up. Suspect the shutter is sticking. If i turn the shooting mode knob the problem corrects itself.

See if you have the mirror up.  This could just be from being in live view mode, or from having set a really long shutter set. Or if mirror is in lockup mode.  Is the camera taking a photo?

Why do so many people say "FER-tographer"? Do they take "fertographs"?
