    I am pretty sure I fixed the issue but follow along if you want. I am curious if I missed a thread that talks about this or not..

    A few days back I was getting ready to fly my P4 and I was using Litchi at first.. I booted up everything in the correct order, controller/app, then the aircraft. Immediately I noticed I was not getting a video feed.. This was followed by a battery communication warning saying to make sure to only use genuine DJI batteries.. Fair enough except that I only use genuine batteries.. When I went to turn off the AC the battery took about 30 seconds to finally shut down. At this point I put another battery in the AC with the same results - then I remembered reading SOMEWHERE (hoping to find the original post) something about the SD card causing strange issues.. I remembered at this point that the night before after getting all the files from the SD card that I deleted all the directories to free up space.. I rebooted the AC and IMMEDIATELY formatted the SD card, then rebooted the AC once more.. At this point all errors went away and everything was green on the AC. I recalibrated everything later that night and I have flown without any issues since that day.
