Way to turn off screen live view on 5d Mark ii?

Is there a way to turn off the camera screen’s “live view”?

My camera starts malfunctioning after 2 hours into shooting an event and i feel its because the camera screen’s “live view” is always on.

I tried to change few settings on the camera but the only option seems to be able to disable it entirely, but i would still like to be able to look at the pictures i shoot on the screen afterwards but not shooting using the screen.

I like using the viewfinder instead to shoot.
