@Siciliano57, the Streambar, like almost all Roku devices, doesn't power off. The power button on its remote is strictly for the TV. If you can't get the remote to turn the TV off/on, try a different code. When it asks you if the music stopped, lie and go on to the next code. I've seen people say that they have problems with Samsung TVs, but I have a very new one and a very old one and I was able to get multiple Roku remotes to control both of them.
