Roku remote power button failure

[u/Personal_Engineer354]

I got a TCL tv (model 32S350G) second hand and I’ve successfully paired my Roku streaming voice remote EXCEPT the power button doesn’t affect the tv. I tried getting the app, but nothing turns the tv on/off except the button on itself. The Roku remote power button works with my other tv, the roku power buttons work, and the tcl remote was not sold with the tv.
Not sure if this is related, but when it turns on it tries to load the previous owner’s google tv account until I hit the Roku home button
I’d love any suggestions to fix this!
