If you have something in your settings called Anynet+ (On the QM75R I was working with, it was in Menu -> System -> General-> Anynet+ (HDMI-CEC)), try disabling it and see what happens. This fixed the issue for me.
I don't know if this was mentioned. But I took the batteries out of the remote. Held the power button for about 45 seconds. Put batteries back in. Turned on tv manually.. Then re paired the remote (back button and play/pause button at the same time) (even if it was still paired) to the tv. It showed ontop of the screen that it was pairing again...(I think this resets the remote) Ever since I did this (a week ago) my tv never turned on by itself..
I recently purchased a q80t tv & q70 soundbar. Connected via arc. The soundbar turns off with the tv, but when I turn the tv on, i need to turn on the soundbar manually as it will not turn on automatically.
