Volume buttons change display settings and activate USB port on Sharp TV
Good morning all, I have tried two different brand new Roku Streaming Sticks with my Sharp 55" Class 4K (2160p) HDR Smart LED TV (LC-55P6000U) purchased from Walmart in November 2017. Rokus were both purchased from Amazon and the current one S/N is YF00GY725002.
Each time I set up the Roku remote to control the TV volume, the Roku remote "UP" volume button changes the source to the USB port in addition to increasing the volume and the "DOWN" volume button changes the display settings (Sport vs. Movie vs. Vibrant, etc.) in addition to lowering the volume.
When intially setting it up, the Roku does not automatically recognize the TV so I have to manually select the Sharp brand. After that the music comes on, does not go off with the first code, but does go off with the second.
I have tried it with and without CEC disabled on the TV and with and without one touch disabled in Roku settings.
I have tried it with the Roku plugged into both the HDMI1 and HDMI3 ports.

Russell, I figured out a work around. I plugged the Roku into a Vizio tv. Programmed the volumn on that tv. Worked perfect. Then moved the Roku back to my Sharp tv and the volumn works perfectly. Not sure if it is just Vizio but give it a try. Takes two minutes.
