Well I worked over a year on my p3s camera and failed, I think Carolina Dronz is a repair center,but not 100% sure. I had same problem as you but had no way to test the equipment,so I couldn't nail down the problem.My P3s is at DJI repair now and the cost to repair for me Is 292.00 ! I am not trying to scare you but just letting you know that it is expensive if you can't test the parts to nail down the problem Best of Luck!
