I have an older LCD TV that has a non-CEC HDMI port and I can't figure out how to use my new TV's remote to power it on/off as well as control the volume. When I go to settings and try to turn on the "Turn On Your TV w/ Your Remote" feature it says I can't use System Control with this configuration. I'm not sure what configuration I need? Or is this message coming up because my TV doesn't have CEC? Is there a way to program the Siri Remote to control my LCD TV's power and volume? Everything I've tried to look up in this forum and other places is so confusing and doesn't quite address my specific issue.
