Hi, @phdwater
Welcome!
To reset your Roku TV, find the physical reset button, which is usually a small, recessed pinhole located on the back or bottom of the TV. Use a straightened paperclip to press and hold the button for about 10 to 20 seconds, until the LED light starts flashing. Then, release the button.
Give this a try and give us updates on what you find out.
Thanks,
