One possibility is a bad SD card.
It's simple to check .. just try it without any SD card, that's the problem..
If it works fine, that's the cause.

Greetings DroneMata, please let us know if removing the SD card solved the issue. Alway handy to know these little quirks.

When I removed the SD card, nothing happened.

The issue still hasn't been resolved.

Tryed playing with gimble roll or calibrating

Tilt motor or gimble motor esc board (controls all 3 gimble motors), not difficult to replace. Thankfully I keep spares so trial and error is simple. Drone tools are your friend.

I have already replaced the Gimbal motor ESC board, but it's still the same. I am planning to replace the Gimbal camera IMU board located at the back of the camera case.Please help

This is the Gimbal Camera IMU board that I'm planning to replace.

 

[Capt KO]

Did you replace the tilt motor? If camera does the warm up routine then drops it might just be a weak motor. Would have expected the esc board but you replaced it. Understand your frustration, I've been fortunate enough to have spare parts on hand.

DroneMata - Did replacing the camera IMU fix your problem?

I am experiencing the same issue as you although maybe not quite as bad (after tilting down mine will drunkenly return to almost level after 4 for 5 seconds - although the camera is still facing down 5 to 10 degrees).

Also in flight lateral movement still has stabilized video but rotational movement results in the horizon quickly becoming out of level and the slowly returning to level after rotation stops.

Also when my drone powers up the camera will go through the usual movements and then center itself perfect. After about 3 to 5 seconds after centering the camera will jerk upward slightly then slowly (not real slow) move downwards to about 45 degress and then come back up to about 5 to 10 degrees pointed down. Pressing the C1 button will move the camera to slightly past 90 degrees and slightly below 0 degrees (around the same 5 to 10 degrees as the "new" zero).

I have tried multiple IMU and gimbal calibrations.

Bonjour à tous,
Je possède un phantom 4 pro V2 qui n'a même pas énormément volé et depuis quelques mois je rencontre le même problème que Steeve. La position du cardan n'est pas fermement à l'horizontale. On a un peu l'impression que le gimbal a bu. Sur une rotation à gauche ou à droite la caméra s'incline sur ses axes tilt et roll. Après avoir remplacé la carte esc de contrôle du mvt par une qui fonctionne nickel sur autre drone j'ai les mêmes mouvements. Rien ne change.
J’ai l’impression d’avoir à faire un problème logiciel volontaire ou pas. Les symptômes se ressemblent beaucoup.

Was this issue ever solved as I currently have 1 camera/drone that does the same. And how was it solved? Thanks

Many years of experience tells me it may be the pitch motor. Just a guess. A video of what it does would help. If the gimbal lock is left on the gimbal it can cause the pitch motor to overheat and sometimes burn out. Any chance that this may have happened?

Are you able to move it back to horizontal

 

[waterwin]

It is a second hand drone and I do not have insight in its history. Moving the 3 axis by hand, when listening very carefully to the gimbal movement I did hear some inside scraping and just did some small corrections. I will do a test run tomorrow and gather some video footage of the sloppy / slowly recovering (=getting horizontal again) horizon.

 

[waterwin]

The mechanical corrections I did yesterday have not solved the slow horizon action at all. I can not post a video here so a link should help, it has a 10 second video showing a quick turn left and the 8 (?) seconds return to horizontal of the camera.

Sounds like the camera IMU board
