Had another problem with my Osmo/X3 last night at a job. Went to use it as I always do but only getting the black screen--no video. Can't control the Osmo, can't format the MSD, etc. Powered everything off/on (Osmo/cell phone), still the same thing. Uninstalled/reinstalled DJI Go and now, DJI Go thinks it's connecting to an Inspire. Doesn't recognize the Osmo. Tried it on the tablet I use for my Inspire. Recognized it as an Osmo but still black screen. Had to postpone the job. Woke up this morning and remembered someone one telling me they removed the MSD card, restarted without it, and that seemed to get it to work. Just tried it and, yup, this worked. Put the MSD card back in, still works. WTF? These little software problems drive me crazy. If I were just a hobbyist, it would be frustrating but not a big deal, however, I'm using some of their gear in my business and it's just horrible. Just thought I'd share a potential solution to the black screen problem.
