I thought I would post this in case someone else experiences the same issue as me with no video feed and an apparent 'non responsive' gimbal. A week ago my video feed stopped altogether from close range (100 feet) with nothing but the DJI logo on the screen (except the telemetry and menu buttons etc).
The video/camera buttons on the RHS of the app were grayed out and did nothing.
The P3 flew fine, but that's about it. When I started the P3 up, the gimbal did it's 'dance' and everything looked fine, but about 5 seconds later the camera would always 'flop' down at an approximate 45 deg. angle and was unresponsive to any rx input. It did this repeatedly. The gimbal was free to move by hand in all directions and seemed perfectly fine.
I also noticed that when I went to turn the P3 off, it didn't turn off straight away like normal, but stayed on (after the 2nd battery press) with all the lights flashing for about 5 seconds and then the P3 turned off...strange.
Of course, I tried different USB cables, different tablets (Ipad mini2 and Iphone 6+), deleted the entire Go app and re-installed, had the 32 channel hack in place etc, but nothing seemed to work - still no video feed and a camera pointing down at 45 degrees.
Then I seemed to remember someone (on this forum) mentioned that a corrupt SD card may affect video feed, so I thought what the heck and pulled it out to reformat on my PC. Even though the card was empty, this fixed the problem! I re-inserted the card and everything worked fine again (the card is a Sandisk Ultra 64mb XC-1). Took a 4000’ flight today with perfect video and no issues. I have the latest P3 FW, and IOS 9.02 on both Ipad mini2 and Iphone 6+
Hope this may help others...
Hi Pete,
I have updated my P3P with IOS V2.40, aircraft V1.4.10, RC 1.4.30. Now when I started up , there is no Video signal from the Ipad mini4 except fot DJI logo. I have tried all the suggestions here but still can not fix the problem.
