Yesterday my Oculus Go Controller stopped working. It never lights up the LED even when i changed batteries. Also I used phone app to detect if the controller is sending some bluetooth signal but it never found it(only found the device(HMD) signal). I assume that the controller has no power in it. Is it possible to teardown the controller and fix it? Has anyone done this in the past? I also contacted oculus support but they asking me for address...etc. Problem is I didnt directly buy my oculus go from online oculus store because it not available in my country. So does my warranty still work if i contact oculus? Or do i contact the store where i bought it? I got warranty list from there for 1 year(bought it this spring).
