My Roku 4 will power my system on after a reboot (usually because of a firmware update), which really annoys my wife. I had to disable the CEC control to make it stop. Of course, I also lost the ability of just hitting the Roku remote to change the TV and AVR inputs, but such is life. My Ultra does not do that, but it's connected to a Samsung TV and the 4 is connected to a Panasonic. Both have Yamaha AVRs. Since the TV is the only difference, I blame my 7 year old Panasonic plasma. But no plans to replace it soon, as it still works fine. I just don't bother with the built in smart apps, because the Roku is vastly superior to all of them.
On the Roku, turn off "Settings/System/Control other devices/1-touch play" and see if that fixes your issu"mike.s" wrote:

Do you have screen saver enabled? If so how long is the timeout?
Do you leave the Roku running in any particular channel when you turn off the TV and receiver?
How are you turning off the TV/receiver? Using the TV remote? The Roku remote?
Is the Roku connected directly to the TV or the AVR?
Please PM to me the SN of the Roku and the time this happens and we can look at Roku activity log at that time to see what it is doing.
