So I had this issue. Here’s how I fixed it. [br]
# Remove power cable
# remove hdmi cable
# press and hold power button for 30 seconds
# plug PlayStation back in to power put a disk in to make the PS4 kick on. [br]
# plug hdmi cable back in after about a minute to give the PlayStation time to boot up
# and voila! My PS4 pro is running like before. I have no idea why this is what worked but hey, at least I’m not buying a new console.
