I am having some problems with my the M, A, S, P Mode on my Nikon D5500. They seem to be quite corrupted, but the other modes look ok (effects, auto, Scene).
When in Manual, for example, I cannot go to previous pictures taken. The i button does not work for setting up the options, and I cannot adjust any setting of aperture or exposure. I have also noticed two flashing lights on the lower corners. On the right low corner, there's an orange flashing light about the FLASH, and on the left low corner is a flashing question mark inside a dark circle.
Is anyone aware of this problem?
