My HMD doesn't display a picture, it flickers when steam VR is first started for a few frames then it is black, with a red LED( sometimes bright green).
Wiggling the headset sometimes flickered an image on the HMD.
What I've tried :
Double checked all connections are plugged in firmly on HMD,Linkbox and PC.
From the linkbox I have tried the usb,hdmi cables.
I have successfully used the Linkbox to run a usb pen drive.
I have confirmed the long hdmi cable from the link box to the HMD works by using it to run a monitor.
I've updated the firmware for every part of the system.
Reinstalled steam VR and verified cache.
And it's still the same.
Updating Nvidia drivers. (GTX 1070, hdmi port tested on a monitor and works fine)
The HMD is running firmware 2097504, when I try to manually update it via holding the button on the side of the HMD and going through the update process it says that it "requires a firmware update" completes it and says update successful but the firmware number in "System report" doesn't change.
