G AM:Hello, can you please clarify - is this setting on the Dish box or somewhere on the TV? I looked on the Joey 4K and found a setting for CeC on the Remote tab of the settings but it didn’t eliminate my error 890.
I apologize, I was referring to the TCL 55R625 TV settings and it gets the satellite signal from the Hopper 3. Please keep in mind that 890 says something like your TV not having enough bandwidth for the HDCP 2.0(2.2?). That is why I went fishing into the TV settings>>>system>>>About>>>Control Other Devices(CEC)>>>Unchecked e-ARC.
I also tried that with the MBR 4K Joey and it did not work because the 4K TV is a budget 4K Insignia model. Again try the TV settings.
Good luck!
