Beam has been connected to LG tv, ARC input for about 3 months. On about 1/12/21 there was a Virgin Media tv outage, which appeared to coincide with an LG software update. The TV & VM box had to be powered off to reset. Since then the Beam cannot be reconnected. Error msg “A device is interfering with the hdmi connection” - But nothing is connected, all is as was before the VM outage

Sounds like it’s possible that there’s some other CEC device that could be sending a malformed connection to the TV’s controller.

Try unplugging all devices from power, on the Sonos, on the TV, on the Virgin Media, and anything else you have plugged in to the TV’s HDMI port. If you can’t power them down, temporarily unplug them from the HDMI port. 

In this order, power things back on.  First, the Virgin Media box, then the TV. Once they’re back on, plug the power in to the Beam. Let it connect to the TV, and test it. Finally, plug back in any devices that may be also connected to the HDMI ports on your TV. Test after each one, it might identify which one is sending a malformed request to the controller on the TV set.

Disconnect everything from the TV including the Beam and unplug the TV and Beam from power for a couple of minutes. Plug the TV and Beam back in but keep the Beam disconnected. Be sure Simplink (CEC) is enabled in your TV settings, then run TV Setup in the Sonos app. Follow the instructions in the app and connect the Beam to the TV’s HDMI ARC port when the app instructs you to using the Sonos-supplied HDMI cable. When the Beam has been successfully connected, connect any other external device to your TV.
