Hi EPopeney,
Thanks for following up.
We appreciate you informing us about the issue with your Roku Express 4k+ that is turning on by itself. We will work with you to know what went wrong so we can assist you further and fix the issue.
Just to isolate and to better understand what you're experiencing. How are you powering the Roku device? If you are powering your Roku by plugging into the USB port on the TV, try powering from a wall outlet via the USB power adapter that came with the Roku. In addition, have you tried using another HDMI port on your TV as well as trying your device on another TV to see if you are seeing the same issue?
With more detailed information, we will be able to assist you further.
Best regards,
Mary
