Troubleshooting HDMI ARC Issues On TCL TV

If you are having issues like CEC/ARC functions start breaking, like getting no sound, not turning on/off devices, no volume control, etc. with your HDMI ARC connections on a TCL TV, there are a few steps you can take in order to get this sorted.

Note: Normally all receivers like audio systems and soundbars do have their HDMI CEC disabled, make sure you have turned them on before attempting further troubleshooting.

Ensure the Correct HDMI ARC Port is being used

The receiver or audio system must be connected to the correct HDMI ARC port on the TV. Not all HDMI ports are ARC-compliant, so you must use the HDMI-ARC ports. 

Due to the fact that ARC is not a source of the video, you won’t get any sound on your TV if you connect an audio device via HDMI to the incorrect HDMI port of the TV.

Reset Connection

Alright, assuming that HDMI-CEC and HDMI-ARC are enabled, the correct ports are being used, but even with these settings, your TCL TV is not detecting ARC and you are unable to control the receiver with your remote or pass sound to the receiver. 

In that case, the connection needs to be reset completely and re-established.

Here’s what you need to do, and make sure you are doing it exactly as mentioned:

  1. Disconnect all TV inputs
  2. Remove all inputs from the home screen
  3. Disconnect the soundbar and TV from the power for 1 minute 
  4. Ensure HDMI is connected, then turn on the power
  5. Allow the soundbar to fully boot 
  6. That’s all, You should hear the sound coming through the arc device (Receiver).

This will reset the connection between your devices and will help resolve any minor issues you’re having with your connections.

Note: HDMI ARC works smoothly only on high-quality high-speed HDMI cables, so make sure that in order to use all functions for ARC as well as CEC you have connected your TV and Receiver with a high-speed cable.

Factory Reset

Ultimately, if all other methods have not worked and you still cannot get your TCL TV HDMI Arc to work, you will need to factory reset the TV.

By doing this, you can restore all settings to the original factory defaults and fix any problems caused by misconfiguration.

This is how you can restore TCL to factory settings:

  1. Press the Settings button on the TCL Android TV remote control.
  2. After that, Scroll to More Settings > Device Preference > Reset.
  3. Select Factory data ResetErase Everything.
  4. Confirm the prompt and wait until the reset completes.

Once completed, plug everything back in correctly and test if HDMI ARC is now functioning properly, and if you are able to control the receiver with the remote as well.
