I have a sharp TV and my new streambar turns the TV off but not on. I've unplugged my device and waited 10 seconds before plugging it back in. Removed the batteries from my remote and re-paired the remote to the streambar. The remote still won't turn the TV back on once switched off.
Re: Roku Streambar only turns tv off. Not on again.
The volume and power commands on the streambar remote are roku hdmi-cec commands. The commands are picked up be the streambar via wifi, and then it sends cec signal over the hdmi cable to control whatever tv its connected to. If your Sharp can't accept cec commands when off, its not the streambars fault, its the tv's. Try refreshing the cec devices in the menu of the tv? Make sure the cec feature is turned on?
