Hi, I had a crash with the Phantom 3 Professional, I change the landing gears and the gimbal with the camera all buy it in the DJI store, but when I try to fly I have a error with the compass and I can't calibrate always have the same error about electromagnetics issues, I check the sensors and the compass is always 0 in all points, what I have to do? I can fix it by myself or I have to take to repair? I openened the case and check that all connections are connected, i don't see any issue, I don't know what to do.

The compass is in the bottom right corner of the landing gear.
If the compass is plugged in correctly, then there has to be some internal damage. I would take it apart again just to make sure.

Here is a photo of where the compass plugs into. The larger plug next to it is where the 4 video/RC antennas plug into. You probably just don't have the compass plug firmly seated.

As well as the top connection, there is also the bottom.
There are 4 fine wores going to the compass in the bottom of the landing gear.
Take the cover plate off the compass and check the 4 wires.
It's easy to break one when you fit the antenna in the landing gear.

I don't know what to say, I'm sorry, your crash must have done some internal damage.

I made this video for you if you can see some malfunction, but seems all is ok,  compass was sticky with this withe glue and when I change it I pull off to unhook and for the new legs I only put in the same place but without any glue or something, the compass have some rest of the old glue.

Thanks for helping me

Try a new compass and cable. You could have pulled a component loose when you pulled the glue off. Or one of the wires could be bad. It is a cheap try.

FWIW all of the P3 series take the same compass..its DJI part 11
