Hi all, I was away for roughly a week and after getting back my DK2 no longer works. The sensor works, since in iRacing it still tracks the movement. However, the screen is black (power light is blue on the HMD). The screen stays black, with the only exception being it'll flicker a white screen for a fraction of a second when I first attempt to turn on the headset.
I have restarted my computer, reinstalled the Oculus software, did a clean installation of the latest Nvidia drivers, double checked and reseated all connections (as well as different USB ports).
Are you on an old Nvidia card? There is an issue now affecting the GTX 780 (maybe others of that generation) where you can get a black screen in Rift. The solution is to install an older driver, 381.89 or 385.41.
Also, if you recently updated Windows 10 to the Creator Update, that could cause a black screen due to the Rift display driver being uninstalled (I actually had this happen to me today on my personal machine). The solution is to go into this folder: C:/Program Files/Oculus VR Runtime Drivers/Drivers/Monitor And then right click RiftDisplay.inf and choose install.
