Roku stick needs to be reset every time I power up my tv
My streaming stick was set up and worked fine. Then after turning off the tv, I turned it back on some time later, and the Roku will not power up. If I reset (Unplug-then-replug) the power wire, the stick works as it should. After the TV is turned off then powered up minutes later, the problem repeats.
If your Roku has a "Settings > System > Power > Auto power savings > After 20 minutes of no interaction" setting, try disabling it.
