Aperture blades dont open 70-200 f2.8

This just started happening with my 70-200 - anyone have any clues ? I'm on a photo trip this weekend and not near a repair shop at all.

When I mount my 70-200 on my D800E the parture blades don't open. When I look thru the viewfinder it is quite dark. When I take the photo all works fine and the exposure is correct. If i turn LiveView on the blades open and the LCD display is normal brightness. It makes taking photos thru the viewfinder nearly impossible. Other lenses work just fine.

Any suggestions appreciated!

In theory, theory and practice are the same, but in practice, theory and practice are different.
