Last night none of the remotes (3) would turn off the TV (Visio-65F). It was responsive to the remotes but not the power off command. In the past, unplug and replug worked, but when I did that, today it would not turn on. So I found the power-on/off button in the back, turned it on, then researched it, went to the System settings on the TV and told it to “reboot”. This seems to have fixed the issue.
Purchased the TV in 2019 from Costco + 3 year extended warranty. Have a year left to go on that. 🙂
