My phantom 3 standard started acting up. I recently replaced the ribbon when all of this started happening. On the DJI Go app it says that the aircraft is disconnected. Also when I go into the status it says that the aircraft battery is N/A. And that the gimbal is disconnected. I went through all the ribbon connections and everything looks good. ALSO, the remote controller light is red. But the drone is green until I try to link it again and it goes back to red. I'm getting flashing yellow lights when I first turn it on. And when I try to turn off the drone, it takes awhile for it to turn off. Any ideas or suggestions?
