@trevor-hall, you should see two model numbers on the "About" screen - the TV's model number and the Roku model number. It's the Roku model number that Roku cares about.
You’re either gonna need to plug it into a power strip or just a simple extension cord. I have a tcl and it happened to me and continued for a week no matter what I tried. Finally I just plugged it into an extension cord and magically it stopped. I’m not sure why this has suddenly occurred on so many roku tv’s. I don’t understand it but this is a quick n “cheap” more importantly fix!!! Good luck.
Yes I do
In my case, a recent update to the TV software changed the issue.
The error came up in a much smaller box, and a button like "close" or "cancel" was available (don't recall the exact text), then the box was removed, without needing to restart the TV. Looks like somone recognized this issue. Not seen error since.
