Solving playback issues

Just got ROKU Express 4K+.  Every time I turn on TV I have to unplug/plug in the power cord.  Tried using power cord from old device, same problem.  Is the issue the actual device rather than the power cord?

Why do you have to do this I might ask? Because you get a “no input signal” from your TV? Your Roku is probably sleeping. Simply press the Home button on the Roku remote to wake it up. You can also disable the bandwidth saver function found under the settings/network. Also be sure your tv does not have any power savings features. Certain Roku models also have a power saving feature. But pressing the Home button will resolve your issues

@sundaemunny-

Newer models like your Express 4K+ have a new "Power" item in the "Settings > System" menu.  An "Auto power savings" item there will put your Roku device into a low power standby condition after a period of inactivity, such as when your TV has been turned off for a while.

Pressing a Roku control key (like HOME) on your Roku remote (not Power, Volume, or Mute which act on the TV, not the Roku) should bring the Roku out of standby and back to full operation. Pulling the power for a few seconds to restart the Roku will restore full operation as well.

The power savings aren't that great and for the hassle it causes, I don't think it's worth having this feature activated.  If you disable "Settings > System > Power > Auto power savings"  it should prevent your Roku from going into standby in the first place.
