Hello everybody !

I encountered an issue since 2 months on my drone Phantom 3 Standard. At each starting (without RC and app on) of the drone, the camera's going crazy for 10seconds then restart the drone and finally get normally initialized. I've recorded it, take a look :


I didn't crashed my drone, i'm trying to be as safe as possible. I went on a trip on May, and as far as i remember the issue was already present before i go. On the place, the problem occured into multiples flights, which had stop the video i was recording. I also miss landed my drone because of wind, he did a "backflip" when it was quite landed (it was on the ground), but the wind pushed him onto a rock which blocked it and then it was on the back, so a ground backflip.

So actually, the problem is still present, i don't know what to do. Do you have any ideas ?

Thanks,
YB.

Hi. Sorry for the trouble. Can you please try to calibrate your gimbal? For reference, please check the video tutorial below. If you have further question, please let us know. Thank you.

I did it and nothing had changed :/

I highly recommend you to send it in for repair so we can asset and analyze your aircraft. You may use this link for online repair request: https://repair.dji.com/repair/index.

Again, we do apologize for the inconvenienced.

Looks like your grub screw at the top of the arm has worked loose. Turn the drone upside down, move the arm to one side and tighten with a  small allen.

You mean this one ?

Oh rather this red one ?

Yes, you have the correct one circled in red.  Make sure it's tightened on the flat side of the shaft.   Let us know if that fixes it.

You should not start it up with the cap on the camera. It's out of balance that way.

Hello ! Today i've tried to tight the grub screw, but it looked already tighted so i didn't forced. I did the gimbal calibration again, without the cache.
However, the problem still here. :/

As he said, remove the lens cap. And turn on rc first, then the ac.

I said I didn't put he cache/cap on while the calibration. I know how to turn on the drone, and anyway how i do it the problem is still present.
Do you have other ideas ?

Look if the flat cable connections are fully seated.

I've pushed these black connections and they look like correctly seated.

So nothing had changed :/

Is there any message in the app?

Maybe you could look at this

Hello, sorry for the delay !
No warning/message on the app.

What's strange is that the issue occurs sometimes, not at each starting, sometimes yes sometimes not.

I've checked today the yaw motor as explained in the video, and it was okay, as the roll motor. I would like to see if the problem comes from the pitch motor, but I don't know know to access it (i'm a little affraid to break the black ribbon).

Can the issue come from the pitch motor ? If so, how can I access it safely ?

Thanks !

Roll sensor boardCould be the roll sensor potentiometer. If it's under warranty send it in for repair. If you're good with soldering you can replace it. Some people just buy the whole board.
I did just the potentiometer for like $5.00.
