Earlier in this thread @renojim already mentioned:
"If your Roku device has a "power saving" option under Settings->System->Power try disabling it"
If that doesn't fix your problem:
If you are powering your Roku via a USB port on your TV that powers down when the TV is turned off, this could be the source of your problem.
When you turn on the TV and the USB port becomes energized, the Roku must start up from a completely power off condition. The Roku may not boot up as quickly as the TV does. If the TV tries to exchange information ("handshake") with the Roku's HDMI port before the Roku has booted up far enough to respond, the result can be that the HDCP confirmation is not obtained. As you have found, powering the Roku down and back up after the TV has started triggers a new HDMI "handshake" on most TVs which then can complete properly.
Some things to try:
- When you get the HDCP error message, try to force a new handshake by switching the TV to a different input setting, then back to the HDMI input to which the Roku is connected.
- Make a point of setting your TV back to a different input before you turn it off so that it does not check the Roku's HDMI port upon initial startup. By the time the TV starts up and you manually switch to the Roku's HDMI port, the Roku may be ready to respond.
But these are both just workarounds. The real solution is to power your Roku via a power source that does not turn off with the TV. On some TVs you may have more than one USB port, one of which stays powered when the TV is off, or you may have a configurable option on the TV as to whether the USB port should remain powered up when the set is off. Lacking this, you can power your Roku by connecting it to house power via a USB power adapter.
In any case be sure the USB source you use, on TV or separate adapter, has a rated output of at least 1 amp.
