Anyone having the display flash on and off intermittently?

It will only stay on for a brief second and stays off for a long period. I've performed the hard restart a few times, changed HDMI ports on the television and tried different HDMI cables. (recently updated to TV OS 12)

Make sure the HDMI cable you’re using is a high speed cable.
I had to try 3 different cables first before I finally solved the flashing issue.
