I went to prep my camera for a shoot on Sunday, and the wheel no longer changes the Aperture setting as it once did, it also does not scroll through the menu items.

I have tried Aperture Priority, and the top dial will change the aperture. So I think this may be more hardware related than software. I have tried a reset of the camera and have had no prior customizations set.

Any ideas on how to get that back to working again? If not - I'll be sending this in for a repair/replacement on Monday.
