No Sound on TV (PROVEN Fixes!)

If you own a TV and the sound stopped working, don’t panic – this is an incredibly common problem. I personally have experienced this issue a number of times.

The good news is that there are several proven fixes that only take a few seconds to try.

I am confident that if you follow each and every one of these steps below, your TV audio will start working again.

If your TV has no sound, you need to power-cycle your TV. Start by unplugging your TV from the wall and then wait fo 60 seconds. While the TV is unplugged, press and hold the power button on the for 30 seconds. Finally, plug your TV back in and your audio issues should be fixed.

It sounds simple, but this will resolve sound issues about 80% of the time!

Power-cycle your TV

Believe it or not, the majority of issues you experience with your TV can be fixed by simply power-cycling your television. Power-cycling just means turning a device off, and then back on again.

Start but unplugging your TV from the wall. While your TV is unplugged, go ahead and located the power button on your TV.

The power button might but located underneath the front center of your television, on one of the sides, or somewhere on the back.

Once you’ve located the power button, press it, and keep it pressed for 30 seconds. This will help to discharge any residual power built up in your TV’s capacitors, allowing for a true reset.

After the 30 seconds are up, wait another 30 seconds before plugging your TV back in.

Go ahead and see if the sound is working again. If not, read on.

Make sure your TV isn’t muted

This is another seemingly obvious step, but you’d be surprised how many times the reason a TV has “no sound” is because it’s muted!

A lot of times, if your TV is on mute, you’ll see a little mute icon on the screen. But that doesn’t always happen.

So do me a favor and try hitting the “Mute” button on your remote a few times just to confirm your TV is not muted.

Check all cables and connections

Some TV connections, or lack of connections, can cause audio issues with your television.

I recommend that you check the following:

  • Make sure you don’t have any headphones connected to your TV – wired or bluetooth. Obviously if headphones are connected, the audio will play through them, and not the TV.
  • Check that any and all audio connections are complete and that they are in the correct places.
  • If you have a cable box or an antenna, confirm that the connections to those devices are snug and correct.
  • Double check that the TV power cord isn’t kinked or damaged in any way and that it is fully connected.

Really the easiest approach here is to just unplug and disconnect everything! Then reconnect it all, ensuring the connections are snug and in the right places.

After everything is reconnected, power-cycle your TV again and check if the audio is working once it powers back on.

Change / reset audio settings

If nothing has worked so far, I recommend you go into your TV’s menu and adjust some of the audio settings.

For instance, if you are not using a sound-bar or a surround-sound system, but instead want to output the sound via the TV itself, make sure your audio format is set to PCM (Pulse-code modulation).

Don’t worry too much about what PCM is, just make sure your TV is set to it if you want audio to come through your TV speakers!

You’ll also want to make sure settings like “TV speakers” is set to Auto, and “Sound Output” is set to TV speaker. The name of these settings will vary depending on the brand of TV.

Some TV’s even allow you to run a sound diagnostic test and a full reset of your TV’s audio. If you see these options on your TV, take advantage of them!

Factory reset your TV

If all else fails, you should try factory resetting your television. A factory reset will return your TV back to the settings it had on the day you bought it.

You will lose all your data, apps, settings, etc. They will all be erased, and you’ll have to re-set everything up again. But your TV will have a clean slate, and sometimes that’s what’s needed to get the audio working.

You’ll find the factory reset option somewhere in your TV’s menu / settings. It’s location will vary depending on your TV make and model.

Here are step-by-step instructions on how to factory reset some of the more popular TVs:

TV has no sound when using HDMI

If there is no sound on your TV when you’re trying to use a sound-bar or sound system connected via HDMI, you likely need to enable HDMI-CEC ARC / eARC. Once you turn it on, go ahead and restart your TV and then check if your audio works again.


ARC (Audio Return Channel) is just a feature that lets you send audio from your TV to a receiver, or sound bar using an HDMI cable.

But most TVs are shipped with this feature turned OFF! You need to manually enable it within your TV’s settings in order to ensure everything works properly.

So just make sure to double check that your TV has HDMI-CEC ARC/ eARC turned ON before proceeding!

Set the audio output as HDMI

If enabling HDMI-CEC ARC / eARC didn’t resolve your no sound issue, I would check that your TV’s audio output is set to HDMI and not TV Speaker.

If it’s set to “TV Speaker” and you have a sound-bar or sound-system connected, your audio may not work.

TV has no sound on some channels

If your TV has no sound on just a few select channels, go to a channel with no sound and press the SAP button on your remote repeatedly to cycle through the settings until you see “Stereo”. This should fix your audio issue.

Press the SAP button on your TV remote

SAP (or Secondary Audio Programming) (also referred to as MTS Multiple Television Sound) can sometimes cause problems with a variety of audio sources. To fix this, just change SAP to the correct setting – “Stereo”.

Many TV remotes will have a dedicated SAP/MTS button that you can use to toggle your TV to “Stereo”. If your remote doesn’t have this button, you’ll have to search SAP/MTS within your TV’s settings.

Check antenna signal

If you’re using an antenna, you want to ensure it’s getting a good signal, otherwise your audio may suffer.

If your antenna signal isn’t great, there are a few things you can do to improve it:

  1. Make adjustments to the antenna
  2. Use an outdoor directional antenna
  3. Use an antenna with a built-in amplifier


When there is no sound on your TV, try the following fixes:

  • Power-cycle your TV
  • Make sure that your TV isn’t muted
  • Check all cables and connections
  • Change your TV’s audio format to PCM
  • Test / reset your audio settings
  • Factory reset your TV

If nothing above helps resolve your television’s audio issues, you should try contacting your TV manufacturer’s support line.
