HT280 No Sound / Not Working – Avantree Support

Is your HT280 all set up but it's not working for you, no sound? Troubleshooting Tips:

· Headphone and Transmitter Base should be well Connected

1. The HT280 headphones should show a solid LIME GREEN light.

2. The HT280 has a power saving function. The transmitter and the headphones will go into standby mode if there is no audio playing for 5 minutes. The headphones will disconnect from the transmitter once they go to standby mode. At this point, you'll need to reconnect them again.

3. If the headphones are not showing a solid LIME GREEN light, follow these instructions to pair: Connect the headphones.

· Proper Audio Signal should be sent to the Transmitter (95% issues are here)

o Is your transmitter LED SOLID (Signal coming through OK) or Flashing (No Valid Signal)?

o Check Your TV settings again (Samsung TV, LG TV, Sony TV, Vizio TV…)

o For AUX / RCA connections

• Use your headphones with a wire to listen. If no sound, then there's no signal coming from that TV port

• Check that the transmitter base switch is set to AUX

o For Optical connection,

• Check that the Transmitter base is set to OPT

• Make sure your TV's HDMI ARC port is vacant/not connected.

• Unplug and plug the optical cable from transmitter

• Start your Netflix / Amazon Prime Program first before changing the TV's settings to PCM

• Contact your TV manufacturer and ask “How to change the TV setting so i can get audio signal out of my port?”
