Apparently, the LG model OLED55CSPUA has an issue with the external device power on/off control. I can configure the IR Bose soundbar well enough, as setup sequence tests it good to control soundbar power. but after exiting the setup, when i press the external device power button on the remote, the TV just wants to cycle through the setup again. It doesn't toggle soundbar power, just cycles back to the setup. i have tried factory settings reset and verified that there are no other devices on the TV.
