Solving playback issues

[countrybob]

Hooked a Roku Express 4K+ to a Vizio model E321MV.  Roku is plugged into supplied USB adapter/power outlet

Setup was successful and everything works as expected.

After the TV has been turned off for a while, when pressing the power button on the remote, the TV turns on, but the Roku does not.  The light on the front does not light up.  The TV shows No Signal.  If I press various buttons on the remote, the Roku will wake up about 10 seconds later and the TV signal is restored.

If I power off the TV/Roku and then power it back on without a long delay, both TV and Roku fire up as expected.

Tried different HDMI cords, different HDMI inputs on TV.  Even bought a different Roku.  Same behavior on both.

Any ideas?

Roku operating system version 10.5 added added a new "Power" item in the "Settings > System" menu for some of the latest Roku models. The new "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 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. 

If you have a "Settings > System > Power" menu item, deactivating any power saving options you find under "Auto power savings" will prevent your Roku from going into standby in the first place.
