Sounds eerily similar to the issue I am having with my 2019 shield. If I change inputs from the shield to anything else, it shuts the tv off. No combination of CEC on/off or power settings on the shield fixes it.so having a weird issue, HDMI-CEC related I guess? I prefer to not use HDMI CEC but I need it turned on in order to use arc. I have the power sync setting under device connection turned off. on my apple tv I have control tv and receivers set to off. Here’s what is happening. I turn the tv on, switch to the apple tv input, and then I manually turn the apple tv on. If I switch to another input (with apple tv still on), and then back to the apple tv input, the TV seems to forcefully turn the apple tv off
anyone have any idea what combo of HDMI-CEC wonkyness I need to tweak? thanks
I've been on Reddit and the c9 thread and no one has any issues with CEC and the shield.
Wondering if the HDMI ports are the issue? I've tried all ports, auto device detect on/off to no avail.
This worked flawlessly on my qled. Hoping the c9 I get delivered Thursday doesn't have this issue
