I have a Bose speaker system. Hooked up to it are TV, Spectrum set top box, Blu-ray player, and my recently purchased Roku. Before the Roku hook-up, everything worked fine. After hooking the Roku through my Bose system, I played a Netflix movie to test it. After about 5 minutes, the entire system shut down (TV, Bose, set top box). Everything is plugged into one power strip, and the strip is plugged into one wall outlet. I unplugged the power strip from the wall, and after several minutes, I plugged it back in. I tried the Netflix movie again, and after approximately 20 minutes the entire system shut down again. How do I fix this?
There's no way the Roku can be powering down your entire system. Your player does have limited CEC support, which can send control signals through the HDMI cable to other devices. One of those commands can be for power. All of your devices would have to support the CEC protocols and accept a power off command from the Roku. Even on my sets that have a Roku remote with a power button, that power button only appears to be sending an IR signal to the TV. If I try to use the power button with the remote shielded from the TV, nothing happens.
But I have never seen any Roku player issue that command while an app is in use and playing a video. I suppose on a long shot chance there might be something defective in the box, that doesn't seem likely. It's more like something else in your HDMI chain might be signaling everything to turn off. My first suspect would be the cable box. Since it's not providing a signal to the system, it might be sending out a sleep command to the other devices.
Try playing something other than Netflix with the Roku, just to see if it continues to happen.
Dan, Could it be that I have too much plugged into one power strip or too much load on to one electrical outlet.
That is something that was in the back of my mind. But even on a 15 amp circuit, I can't see that number of devices overloading the circuit. A defective power strip is certainly another potential thing that could be checked. Many power strips today have current monitoring circuits with surge protection, and a failure there might show up as a power shut down that might appear to be operating normally when you turn everything back on.
If the Roku is showing the boot screen when you turn everything back on, that would indicate a loss of power, not just a simple power down that the power button would trigger. The Roku is never "off", just goes to sleep. So if you see the Roku bouncing logo when you turn the TV back on, the Roku lost power. And there's no way the Roku could have done that.
Might this power strip be a so-called "smart" strip that senses when whatever is plugged into a "master" outlet (often the TV) powers down and automatically shuts down the other outlets?
