CV1 Black Screen - Sound is ok, screen is detected (NVidia Panel from PC working properly)

Honored Guest

Up until November, my CV1 was working properly. But on December 2nd I was going to use it as usual, but the display was off/black. When I connect Oculus CV1 to the computer:
  · The device is detected correctly.
  · Tracking is enabled.
  · Proximity sensor displays White/Orange led light ok.
  · The displays remain black or off.

When I put on the headset, Oculus Store/Library opens as usual but I can't see the oculus home on the displays. Using a tool called "HomeUnhider" (from this post) I can see what it is actually rendering to the hmd on a desktop window. This way I can control the Oculus Home, because tracker, controller and sound (on the headset audio) work. I checked all of this on some different computers with the same results.

This is my configuration:
   · Intel Core i7-4790 CPU @ 3.60GHz
   · 16 GB RAM
   · OS Windows 7 Enterprise 64 bits
   · NVidia GeForce GTX 980
   · Last Nvidia drivers running

Attached are the logs gathered using the tool commented here. The only thing I've found that called my attention is this (from OculusHardwareLogs/DeviceCache.json)
"sdkMessage":"No HDMI cable detected",
Could this be an issue with the hardware of the displays? (as everything else seems to work).

Many thanks.
