Welcome to our community, tomdufour.
If you haven't already done so, please try power-cycling the TV by turning it off and unplugging it for several minutes. This should serve to reset the TV hardware.
If the problem persists, I would recommend disconnecting your sound bar to see if the problem continues. This will help identify if your TV is at fault, or if there is an issue with the sound bar or the handshake between devices.
Please let me know what happens? I look forward to hearing from you.
