I had a crash into a wall, moving sideways and the top popped off. Popped the top back on fine. Camera works, flys fine, replaced blades, but discovered the gimble had come apart a little. Popped it back together. It all moves around fine and the camera works fine, but you can't adjust the camera tilt nor flip for verticle shots.

Suggestions???

I tried restarting, calibrating, but it gives the gimble error. Looked at new cameras, but half the price of new drone.

Anyone know anything simple to try?

Send it in to DJI for repair. Gimbal repair is guesswork and can work out expensive if you guess incorrectly.

My experience with DJI repair is that it is usually reasonable.  Besides that parts are not the easiest to find either for a DIY repair.
