Purchased a Phantom 4 Pro used and controller battery is beeping and in need of a charge. Only the first of four lights lite, indicating controller is in need of a charge. Plugged the controller in - alone - not with battery, and first light will flash but it will not charge.
Searched the site and found similar problem that was solved by recalibrating the sticks and gimbal wheel on controller. I watched the recommended video, calibrated controller sticks and gimbal. Tried it again - still will not charge. After approximately 5 minutes controller beeps and then shuts off.
Controller did have a charge because I was able to use it when I first unpacked everything. I've had the P4 and controller out twice and flown with no problem. I have been able to charge the battery so I don't think there is a problem with the charger.
I have tried to connect controller with the DJI Assistant app using my desktop and laptop but it will not connect.
Help please.
