My new (refurbished) EM-10 has developed a fault after a few minutes of use and I was wondering if anyone here had seen and fixed this fault before. I am running V1.1 firmware and after shooting a few shots with my 45mm f/1.8 I turned the camera off and put my 15mm f/1.7 on. When I turned the camera back on I was presented with the live view screen but the image was black (as if the lens cap was on), however the aperture value shows -.- and when I try the EVF I get the same thing. I've tried all of my lenses and the symptom is the same, and all lenses work just fine on my EM-1. I'm well within the returns period but before returning is it worth a firmware upgrade or does this sound terminal?
