I have a two year old Roku TV and a two year old Roku soundbar that are now not connecting.
Please read - When I unplug the HDMI cable and plug it back in, there is a white speaker icon and a circle/clock with "20" next to it. on a black background in the upper right corner of the TV for 3 seconds. It then disappears. It is as if the speaker starts to pair, gets to 20% and then stops.
Roku's do not show percentage of pairing. First thing you have two Roku's, meaning you have two different home screens. If you use the Soundbars remote you will always go to home screen on the soundbar, no input tiles. The roku tv home screen has the input tiles. With Roku tv remote go into the settings of the Roku tv:
settings> system> control other devices (CEC)> search for CEC devices> ok
Now try just pressing the Home key on the Roku Soundbar remote? If you're using the Roku soundbar for just better sound and are content with apps available on your Roku tv, put away the Soundbar remote for good.
