I really want the Unicorn Hat HD to work but I am on my second HD now. I’ve confirmed that the HD is connected properly to the RPi3 B and I am running from a fresh install of NOOBS (I’ve tried a fresh install twice). ps aux | grep python shows nothing else running. A Sense Hat that I have works fine on the same RPi3 B.
No lights on startup and none of the examples work. Is there anything else I can try before trying to replace/refund again?
