Astra S: No depth image

Both on Linux and Windows I don’t get any depth image any more. Camera used to work but suddenly it stopped working.
What we noticed is that once we start NiViewer, the IR projector stops working.

Things I tried:

  • Upgrade FW to 1.07, no difference
  • Downgrade FW to 1.04, no difference
  • Turned off proximity sensor, no difference

Do you have any suggestions?

Appears that we have a camera from before Oct. 2015 which needs different FW.
