TV Headphones / Transmitter Troubleshooting - with Samsung / LG Smart TV

The main problem with Samsung and LG Smart TVs is that they have built-in Bluetooth and will aggressively pair with any available Bluetooth device in the vicinity, including your Bluetooth TV headphones & transmitters. If you mistakenly pair your transmitter with your Smart TV, it will break the connection between the transmitter and headphones, causing you to lose sound in the headphones.

Bear in mind before we start: 

1. If your headphones / transmitter suddenly stopped working with your TV, it may be because your Smart TV performed an automatic update and reset all of its settings to the defaults. After this automatic update, you will need to follow these steps to troubleshoot the issue.
2. The TV remote control does NOT turn Smart TVs off. It only puts the TV into standby mode. The TV will still perform its "Smart" functions in standby mode. The best way to turn the TV OFF is to physically switch it OFF or to pull the plug.

Here is the FIX for the above issue with Avantree TV headphones and transmitters.

1. DENY / REMOVE the Avantree Device from your Smart TV's "External Device List."
2. Turn the TV OFF (not in standby), then reconnect the headphones and the base. 

DENY the Device:

When the Samsung Smart TV detects your Avantree Device, a popup will appear on the screen, asking you to allow or deny the device to connect with the TV. You MUST DENY the device from connecting, otherwise it will not be able to connect with the other device in its set.

SAMSUNG:

LG:

REMOVE the Device:

If your device connected to your TV by mistake, you will need to remove the device from within your TV's settings. First, turn the transmitter OFF, then:

Samsung:

Settings >> General >> External Device Manager >> Device Connection Manager >> Device list >> Edit >> Select all Avantree Devices >> Delete 

LG:

After denying the initial connection request or removing the Avantree device from the Smart TV's external device list, your Avantree devices should work properly now. If not, go next: 

Turn the TV OFF and reconnect the devices:

1. Turn OFF your Samsung Smart TV. Either flip the physical switch on the TV, or pull the plug from power. If you cannot physically turn OFF your TV, try to press and hold the power button on your TV remote for 6 seconds until the TV turns off.

2. Turn on your headphones and transmitter. Please have your transmitter plugged into a wall outlet, not your TV, as the TV should be off at this point.

3. Get the headphones and transmitter into pairing mode (rapidly flashing RED & BLUE). For more information, please refer to your devices' user manual or support site. 

4. If your headphones and transmitter have a LOCK function, please LOCK the headphones and the transmitter together. For more information, please refer to your devices' user manual or support site.

Now, the headphones and transmitter will be locked together, so that the next time you use them they should automatically re-connect with each other and show solid BLUE on the headphone. NO need to re-pair them each time.
 

No sound for using Sony TV:

If there is  no sound when you connect the transmitter with your Sony TV via optical cable, please go to the settings of your TV using your Sony TV remote:

1. Press the (Quick Settings) button on the remote control, then select [Settings] — [Display & Sound] — [Audio output] — [Speakers] — [Audio system].

2. If the audio system is not compatible with Dolby Digital or DTS, set [Settings] — [Display & Sound] — [Audio output] — [Digital audio out] to [PCM].

3. Check if the [Digital audio out volume] setting of the TV is at maximum.
Press the (Quick Settings) button on the remote control, then select:
[Settings] — [Display & Sound] — [Audio output] — [Digital audio out volume]
