Left Controller buttons and joystick have stopped working

My left controller now no longer works in regards to any analog input EXCEPT the system button. The system button turns it on but it does not pair. It does pair if plugged in, whether to the computer or to the usb on the front of the headset. When I do this I can now use it and it tracks hand position and finger position. But I am not able to move in any game or hub with the joystick and cannot use the buttons.

By extension this means I cannot manually pair it either since the b button does not work. This caused me great frustration be fore I thought to plug it in and try it. Since the re pair instructions say to hold System plus b to re pair.

Is there any precedent of this occurring? Is there a guide for taking apart the controller and Identifying the problem? And if not where would this problem be? somewhere on the board I presume.

Thanks in advance for any replies.
