Hello pugilicious,
I apologize for any inconvenience this issue may have caused you. Upon review of your account I see a ticket has been opened for a member of our Advanced Support to reach out to you regarding this matter. It can take up to 72 hours for a response. As a side note from personal experience, if the volume of the TV is turned up too loud, it can interfere with voice command and cause this error message to pop up. Try turning the TV down when using the voice command and see if that works. You may also want to try if that doesn't work to unpair and repair the remote to your TV by doing the following:
- Press the Setup button on the remote until the LED at the top of the remote changes from red to green.
- Press 9-8-7.
- The LED will blink green twice indicating that the remote has been unpaired.
(to re-pair the remote to the new box)
- Press the Setup button on your remote until the LED at the top changes from red to green.
- Press the xfinity button on the remote. The LED will begin flashing green. (Note: When pairing an XR2 or XR5 remote to a DTA, you may need to press the xfinity button up to five times).
- Follow the on-screen pairing instructions to enter the three digit pairing code.
- Once the on-screen pairing code is correctly entered, your remote is paired with the set-top box.
Thank you for being a valued Comcast customer and for your patience as we work towards a resolution for you.
