new to Roku this week and things were great until 30 min ago. Turned everything off to walk the dogs, came back and everything on Roku device has a magenta cast, including the menus for the Roku itself. (So likely not an HDCP issue)
It is a brand new Ultra 4670, with the latest 9.2.9 4143-46 build. it is on a wired connection, with hdmi into our receiver. I’ve rebooted, changed cables and ports on receiver (other devices in same port work fine), so I’m fairly certain the issue is in the Roku, which itself is less than than a week old.
