My mavic shows black screen on app, the gimbal works fine but can’t take photos or video. I’ve changed the ptz cable and ribbon cable but still has same issue
Mavic pro black screen, please help

That might test/fix OA sensors, but doesn't account for no image shown coming from the gimbal camera.
With all those errors, sounds like a board problem or connections to it.

If the telemetry ok and the whole vision system out of order then is´nt only the gimbal at all,then whole cam for record and cams for positioning are not responding. Look at the mesages once more.
It´s a case for diagnose and repair at once.

Ferkemup has the fully telemetry and all error messages on screen,the whole vision system is failing completly.
I’ve replaced the ribbon cable, and I have no images(black screen)or gimble mobility. Possibly change the signal cable?
There are tiny resistors on the gimbal top board where the video signal cable connects check if any one is missing.
If one is missing just solder the pads together and it will work.

Hello, can you please mark which resistors you think? My drone after change gimbal arm and cables dont send any image to app... i didnt know if the camera or cables are bad so i ordered new video signal cable but after changing nothing happened and i still get black screen on app (ofcourse i tried more phones, different cables,fw upgs,many apps and so..)
BUT i tried connect that camera to my old dissasembled SPARK bcs they have the same video signal cable connectors (only video,no gimbal) and image was alive, so i can say the camera sensor and cable is good.
My problem is in question if i have broken gimbal camera board or some other module placed behing it ?
Notice : My mavic dont shows any warnings about camera or gimbal and no matter if they are connected or no
When i press recording button or when i try to switch in app from photo to video mode, nothing happen and when i take photo i can hear sound but there are nothing in gallery and nothing on sd card too. When i fly, the telemetry show normal and nothing is showed as N/A .
I spend about 30 hours with it and my hair starts to get silver :-D
I need to know if i should order gimbal board and if it would be resolve of my problem :-/
( posted image of my board if someone can give advice )
THANK

Yea thats the last thing I have left to change. I changed the gimbal board and still no image. I haven’t crashed my mavic so i don’t see why the camera itself would be broken but that’s the only thing I haven’t changed but maybe could explain why if I take a picture it makes the noise but there’s no picture anywhere to be found not even a picture of blackness
I have the same problem never crashed, havent flown my mavic pro in 3 months last time I flew it I had video as normal. Changed ptz video cable still no dice Black image. Did you end up resolving your problem? The way I see it all that could be wrong now is either the gimbal board, the gimbal board to main core ribbons, or the core board itself.... Even of thats the case, there's no reason a perfectly good mavic pro just decided to say "no video for you anymore mister" just from sitting in storage for 3 months in a climate and humidity controlled space. All 3 Batteries in storage and even remote's battery in storage(55%)
No I never figured out what was wrong. I still fly with black screen lol. But I did read something, can’t remember where I read it, but it said something about the nand chips? I’m not sure what they are but it said after sitting up for a while they mess up. And mine sat up for like 3-4 months then stopped working so I think maybe figure out what or where these so called nand chips are and replace them. Let me know if you figure it out
found something. It says for the phantom but I think the same applies for mavic pro.

After a few years of helping people with this issue, I've noticed some common questions crop up. Here is a little more background and a few more tips that I've put together over the years. I hope this helps P2VP fans get back in the air one way or another! Root cause: It all stems from DJI doing

i will search online and see if there's a similar procedure that can be done to the mavic pro. I am guessing the nand you mentioned, is placed on the gimbal board of the mavic pro in our case. I will research and keep you updated when i find something worthy of notice. thank you so muchfound something. It says for the phantom but I think the same applies for mavic pro.

ok i remember seeing this little ribbon conenctor on the side of the gimbal board which is put there for servicing by dji, in this picture here taken from another forum you can clearly see it. I do notice tx and rx pads, and 3v3 pads and gnd pads on the gimbal board, and the unused ribbon connector that is circled is probably used for this exact procedure. however, we run into a problem. first, there is no way for us to get ahold of a ribbon cable that hooks up to this connector. second, if we were to use an ftdi adapter (like the man does in the p2 repair you mention) we will need mavic pro specific flash files. That is all considering that my theory is correct and the nand chip is actually located on the gimbal board and not the core board of the mavic pro. I will check into a github page which i used to read a long time ago from a member called mephistoteles, he had done a lot of work and reverse engineering on the p3. lets hope i will find something that is helpful for the mavic pro. Btw, i wanted to ask you, did you try replacing the actual camera module? i am waiting on a "bad" one that wont focus from a friend who just shipped it to me. If it turns out that i still get black image then our problem is down to the gimbal board, or the core board and your nand chip theory is going to gain much more ground. I will keep in touch, lets hope we can fix this

I have not replaced the whole camera/gimbal setup but I have replaced the gimbal board and no luck. So my guess is it’s either the WiFi board or the core board
oh my, so the gimbal board is out of the question then. About the wifi board i think that it doesnt have anything to do with image transmission per se, as much as it has to do with the wifi connection when you are flying only by phone (switch the side selector to wi-fi). Dont know for sure though
I replace the ptz and gimbal ribbon cable even though the gimbal works flawlessly. whats weird is that recording and photo taking doesnt work, it seems to be glitching on mine. I have tried several sd's which i use in my mini2, mavic2pro and mavic2zoom but even after formatting them on a pc, or onboard the mavic it wont record anything, just creates broken video files!!! I hope to god its not the core board, such a waste
