a6000 not changing aperture

[Angie]

For the first time tonight I am unable to change my aperture while in Manual mode using the upper right wheel, I have an a6000. It has never done this before, when I click that wheel in either direction it will bounce between f11 and 13 but will not go higher or lower than that. Help?!

Sounds like it might be a MENU setting problem.  Does this happen with all of your lenses?  When you select A mode, can you select the apertures?

If all else fails, go into MENU SETUP and choose DEFAULT SETTINGS.  This will get you back to the basics.  Restart the camera and tell us if the problem still occurs.
