Facing TV Problems? Ask a TV Technician.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, bear with us; re-confirm and post back with the complete model number of the "...lg smart tv...sound bar..." Additionally, please describe how the soundbar is connected to the TV using what kind of cable(s).
And is the TV directly connected to an antenna? ...or is there a satellite receiver or a cable box?
