How To Fix TCL TV Headphone Jack Not Working?

Asking why is the TCL TV headphone jack not working? You’ve just found the answer!

Generally, the headphone jack of Roku is located on the remote, but there is also an audio out 3,5mm jack on the TV’s back panel.

We will make sure to go over both of the jacks and provide you with sufficient troubleshooting solutions by the end of the guide!

To fix the headphone jack of your TCL TV, increase the volume and check the mute state of the device. Do a soft reset on your TV and fix issues with the Roku remote. Lastly, check the sound output through different headphones connected to the jack.

With that being said, let’s proceed to fix both of your TCL TV jacks and discover the origin of the problem to prevent it from appearing in the future.

How To Fix TCL TV Headphone Jack Not Working?

Before we move on to any of the solutions, you should restart your TCL TV first.

We will later get you familiar with a more advanced way of restarting your TV, but for now, make sure that you hit that power button on the remote twice, to restart your TV.

If the reboot didn’t help solve the problem, let’s proceed with the solutions:

Solution #1 Increase Volume/Unmute

If the headphone jack doesn’t seem to be working, although you have the headphones plugged in, you should check the TV’s volume and the mute state.

The jack might be functional, but if you lower your TV’s volume all the way down, you won’t be hearing any of the media or mp3 you’re playing.

In that regard, through your Roku remote, press the volume button 5–10 times to check if this will solve the problem.

Moreover, ensure your TV is not muted by pressing the Mute button until the indicator doesn’t have a cross when it appears on the screen of your TV.

Play Different Media

You should also attempt to play a different media through your Roku TV.

The current music file or movie you’re viewing might not have sound, therefore the headphone jack along with your headphones themselves, won’t be functional.

Note: Remember to test your TCL TV’s headphone jack after each of the upcoming solutions.

Solution #2 Soft Reset Your Roku TV

If you’re not hearing anything coming out of your headphones when connected to the jack on the remote, you should soft reset your TV.

There might be a bug or glitch that is temporarily messing with your device and by performing a soft reset (power cycle), you could easily resolve the problem.

Here’s how to soft reset your Roku TV easily:

1. Turn OFF the device using the remote.
2. Unplug the A/C power adapter of your Roku TV.
3. Wait for 5 minutes until the device is completely discharged.
4. Re-attach the adapter and test your TV.

Pro Tip: Avoid using any power strips or dividers to supply your Roku TCL TV with power, since they can be carriers of power issues for your TV.

Solution #3 Troubleshoot The Remote

The headphone jack on your remote also requires power to supply your headphones.

If your Roku remote’s batteries got worn out the headphone jack would also become nonfunctional.

We’ve formed some easy troubleshooting approaches towards your Roku remote:

How To Discharge Roku Remote?

1. Turn your Roku remote upside down.
2. Press the battery compartment’s latch upwards.
3. Eject the batteries.
4. Press each button on your remote for 5 seconds.
5. Re-insert the batteries and test.

If that didn’t work, replace the batteries of your Roku remote.

How To Replace Roku Remote Batteries?

1. Again, turn your remote upside down.
2. Remove the battery compartment and eject the batteries.
3. Depending on the model, insert the fresh set of AA or AAA batteries.
4. Close the compartment and test.

Note: When replacing the batteries, double-check if you’ve inserted them into the correct position so they make contact with the electricity poles.

Solution #4 Re-Pair The Remote To TV

There’s a chance that the remote got disconnected from the TV. In such a case, you should perform a re-pair sequence, so the Roku remote gets connected.

To re-pair your Roku remote with your TCL TV, follow the instructions below:

1. Take your Roku remote.
2. Ensure that your TCL TV unit is up and running.
3. On your remote, locate the pairing button at the tip of the device.
4. Press and hold the button for 30 seconds until your TV blinks.

If you see the blinking, this means that the remote has been successfully connected to the TCL TV and the headphone jack will start working now.

Note: When repairing, make sure that your remote has a good view of the TV, hence, there are no objects or wireless devices nearby, interfering with the infrared signal.

Solution #5 Use Different Headphones

The problem might not be with your headphone jack on TCL TV or remote.

Instead, you should attempt connecting an alternative headphones/sound device to the jack and check if that would solve the problem.

In general, Roku also supplies you with headphones with the given remote, but they could easily go faulty if not taken care of.

In that regard, acquire a different set of headphones that use a 3,5mm jack and connect them to your remote. Play anything on your TV and listen for an output coming out of your headphones.

Note: Fit the 3.5mm jack tightly and listen to output when rotating. 

In case you hear fractions of the output while rotating, it would mean the jack is either dirty or broken.

TCL Roku TV Headphone Jack Not Working Audio Out?

In case you’re not having issues with the jack on the remote, instead, you’re not able to get sound out of the jack inbuilt in your TCL TV, we’ve got you covered as well!

1. Clean The Jack

Users recommended cleaning the jack out of any dirt that is interfering with the 3,5mm jack’s entry.

Make sure to blow once or twice into the jack to remove any dust particles inside.

2. Configure Audio Settings

When using the jack on the TV, you need to go to Settings > Audio Preferences > Devices and choose your sound output device connected to the audio out jack.

3. Try With A Different Device

The current device you have plugged into the audio out jack of your TCL Roku TV might be faulty. Plug an alternative audio device and test.

Note: The workarounds above will be also effective against issues with the remote’s jack.

Thus, to fix the headphone jack of your TCL Roku TV or remote, first power reset the device and clean the jack. Then, re-pair the remote with the TV and configure the audio settings. Replace the remote’s batteries and test with another audio device.
