Hi all, I have a P3 professional purchased in november 2015 here in Italy. I flew it only 5 times without ank kind of problem. Last flight was in june. two days ago I recharged both the controller and the battery but when I powered on the drone I discovered the camera doesn't send anymore the video signal. I tried to use different tablets but nothing changed. After this, since the fw was very old I tried to upgrade bot the controller now is at the latest release but the drone sistematically fails the upbrade. I tested using all the releases available on the DJI site. I tried alsto to reformat the sdcard... i tried also a different sdcard. nothing! the camera doesn't send the video. Now the djgo declares all the platform is upgraded but the upgrade process still finishes with a indefinite DDDDDDD sound and the text log reports only upgrade FAILS and the video is absent... Any suggestion ?
