All I get is a no signal message. It has been like this for more than a week. I the ROKU system done.
@George1943, disconnect the power to the Roku device and reconnect it. Does anything appear on the screen? Does any light on the Roku illuminate? Are you certain you're choosing the right input on your TV?
Dies this occur when you first turn on your TV? Does pressing the Home button on your Roku remote?
If so:
If your Roku has a "Settings > System > Power > Auto power savings > After 20 minutes of no interaction" setting, try disabling it. More info on this setting: https://support.roku.com/article/6306527767575
