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 TV.
Still, it would seem that the TV has paired with a Bluetooth device on Channel 2 and is awaiting further action. Offhand, turn off any pairing between the TV and any Bluetooth device.
