I did a quick search, and found some similar but not quite the same problems, none of those solutions worked, so hopefully this is enough info...
I'm happy to take this thing apart, (as is evident by disassembling the camera/gimbal to replace the video cable and successful replacement of ESC board), so any advice or ideas gratefully received (except the "send it to DJI" ones, I can buy the bits and do it cheaper myself once I diagnose the problem). Currently I suspect the camera/gimbal control board.
Problem?
No video displayed, no control of camera or gimbal.
Gimbal shows as 'N/A' in the overall status.
No camera icon or settings in main menu (3 dots, top right of Go4 app)
Air Encoder (0x800000) error.
Usually a Vision Sensor Communication error as well, but only 90% of the time.
SD card cannot be read or formatted.
Gimbal slaps about quite violently at start up, and sometimes at apparently random times, some posts I've read say this happens to them all the time, others that it isn't normal.
Camera always ends up pointing downwards.
Was unit in a crash?
Definitely.
Was bought second hand from someone who had stuffed it into the ground quite hard (judging by the damage to the aluminium bottom plate - It cracked round the front right screw hole) - yes it was dirt cheap enough to be worth fixing up.
Original issues were this camera problem, and no action from the right rear prop (since fixed by new ESC board).
Gimbal took a hit (cable cover on lower right side and bottom of camera show some damage).
What have you tried so far?
SD card - have tried formatting in windows PC, Mac and GoPro first, still not recognised. Only currently have one Micro SD card (Sandisk Extreme U3, 16 GB), waiting on delivery of 2 new cards.
One of the flat cables from the camera control board to the main board was damaged, and has been replaced (came as a set of 3 cables, so I replaced the other one to the main board, and the one between the main board and ESC as well, since I could).
Some strands of the video signal cable looked slightly damaged, so replaced that in case that was causing the lack of video. Have not yet replaced gimbal ribbon cable, as the gimbal moves and the cable shows no signed of damage).
Have tried downgrading, then upgrading firmware, which took a few goes (possibly due to dodgy internet connection, Australia is the Third World of the Broadband).
Firmware is the current latest version (.500 on aircraft and RC)
Resetting camera results in "Restting Failed"
Forward vision sensors calibrate OK, and the onscreen 'RADAR' display seems to be working OK also, though the comms error still appears.
What device are you using ( iphone , ipad, Samsung , etc)?
Samsung Galaxy S9 and Samsung Galaxy Tab S3
What firmware are you running ( aircraft, remote controller)?
Both at latest (.500), refreshed today after install of new ESC board.
What Go app version are you using?
4.3.16
Any modification?
No
Did you change anything or install any apps?
No
Do you have a video or pictures of the problem? (if so post link)
Hopefully clicking the thumbnails brings up a bigger image....
