I recently bought a pre-owned DJI Phantom 3 advanced. When I started the Drone up there was a slight buzzing, or almost humming sound coming from the middle of the Drone. It's definitely not a fan and the Drone still flies perfectly. When I calibrated the IMU the buzzing seemed to stop temporarily but then started up again. Has anyone had this issue, does anyone know what the problem is? All firmware has been updated. It's a slight buzzing sound almost.. and it's quite annoying, is this supposed to be like this? The previous owner said it was always like that.

Sounds like the gimbal as it works to keep the camera level - there is a fan in there that can also create a noise like you describe.
Double check all the screws at the gimbal - does the sound change when you touch the gimbal - if so, it's a resonance happening (gimbal housing reacts to fan rpm.
It might help to loosen the screws and re-tighten them in a different order - this process works often with equipment experiencing resonant issues - worth a try.

OOPS - I stand corrected it is the 3 Pro that has a fan - not the standard or the advanced - thanks Dawg!

No obstructions, I checked the screws too, nothing seems to be out of order, I'm going to try to loosen and then tighten them again and see if that helps at all. The sound does not change at all if I touch or move the gimbal around

Perhaps you are hearing the fan under the OFDM board (where the VPS is also located). You can see where the fan is located by looking in the battery compartment. I realize it's hard to be sure with a sound like that, but does it seem like it's coming from that area?
Actually yes, it seems like it might be. It's coming from directly above the gimbal, basically right where u r saying. It's tough to tell but its definitely coming from the middle of the drone in that area (thanks everyone for insights) I am determined to figure this out..lol
Fyi...turning and tightening screws didn't seem to help much.
If it does turn out to be that fan, is this anything I should be worried about, what can I do?
