Now that we’ve reviewed the possible problems, let’s proceed with the best troubleshooting solutions we’ve managed to extract from users that solved this issue in the past.

How To Fix Toshiba TV Sound Problems Easily?

First of all, have you tried rebooting your Toshiba TV? Such problems will most often be caused by issues with the power flow, so make sure to try a firm reboot before applying any of the following solutions.

If a reboot didn’t work and there’s still no sound coming out of your Toshiba TV, proceed with the first solution:

Solution #1 Perform A Power Cycle

Begin the troubleshooting process by power cycling your Toshiba TV.

This will actively discharge the device out of any remaining electricity, which will hopefully fix any sound issues that might have developed.

Here is how to power cycle your Toshiba TV:

1. Turn OFF your Toshiba TV using the hardware remotely.
2. Unplug the power adapter and wait for 5 minutes.
3. Once 5 minutes have elapsed, re-attach the power adapter.
4. Test your TV’s sound.

In addition to the power cycle, try plugging your TV into a different wall outlet or power source in general.

The issue may be related to your TV’s power source, so make sure to plug it in a wall outlet that is proven to work well.

Solution #2 Unmute TV/Increase TV Volume

It is possible that you’ve accidentally muted your TV or lowered its volume all the way to zero.

We recommend checking the Toshiba TV’s mute status and making sure its volume is increased as well.

On your remote, there should be a mute button that will both mute and unmute your TV.

Press it once to determine if your TV has been muted by accident, then try increasing the volume.

If that does not work, leave the mute and volume as they are now, and proceed with the next solution.

Solution #3 Choose Different Input

You could be losing the sound on your Toshiba TV due to an improper input configuration.

For this solution, we suggest choosing a different input on your Toshiba TV in an attempt to identify the origin of the issue.

The input could be DVD, SAT, AUX, or cable network. Make sure to choose an input depending on what you rely on.

If you choose the wrong input it most likely won’t match with your device.

The best way to test your audio would be if you have a simple TV channel (Wach TV). 99% of these channels will have good audio so testing on them while in this guide is highly recommended.

Solution #4 Disconnect Speakers

The next solution we recommend is to disconnect any external speakers paired with your TV.

It could be your speaker’s fault as to why you’re not hearing any sound coming out of your Toshiba TV and the best way to test that theory out is by disconnecting them.

Your TV would automatically choose the different sound output and start producing sound.

As for your speakers, make sure to check them on another device and if they keep failing to work, get in touch with a mechanic to diagnose them.

To disconnect speakers from your Toshiba TV, unplug their AUX cables from the back.

Also disconnect all other consoles, headphones, and devices connected to the TV so the device can use its own speakers for audio output.

Solution #5 Disable Secondary Audio Protocol

The secondary audio protocol, called “SAP” in short, is a feature designed for non-native cable television users.

If you’ve accidentally turned that on, there could be a big interference in the sound of the original broadcast and the sound you hear.

Check if you’ve switched it on with the steps down below.

1. Open the settings on your Toshiba TV.
2. Visit the sound options and toggle MS, AUDIO, or SAP to the off position.
3. If you can’t find the SAP feature, look for “MTS” and change it to “STEREO”.

Once you’re done, save all the changes and exit to the menu. Try playing something on your Toshiba TV to determine if the sound is back by now.

Solution #6 Reconnect ALL Cables

If you have any speakers plugged in and you’re certain that they work after solution #3, perhaps the issue is found within your cables.

For this solution, make sure to reconnect all AUX cables in your TV/sound configuration and that there is no damage inflicted on the cable’s hardware.

If any of the cables are faulty, make sure to get a replacement as soon as possible to fix the sound issues on your Toshiba TV.

Solution #7 Update Your TV

The next thing we suggest is to update your Toshiba TV to the latest firmware version.

A quick reminder for users who have Toshiba Fire TV sound not working issues is to update their firmware too as this is one of the most frequently reported causes.

Here is how to update the firmware of your Toshiba TV easily:

1. Make sure your Toshiba TV is connected to the WiFi.
2. Visit “Home” from your remote and open the settings.
3. Tap on the “About” tab.
4. Select System Update and proceed with the on-screen instructions.

Your Toshiba and Toshiba Fire TV will restart during the process, so you must make sure their power flow is not compromised during that time.

Solution #8 Factory Reset Toshiba TV

For the final solution, you can try factory resetting your Toshiba TV.

This process will reset all configurations made to your TV, hopefully fixing any sound issues your TV has developed over time.

Here is how to factory reset your Toshiba TV:

1. Go to the Home tap and open the settings.
2. Scroll down to the “Device and software” tab.
3. Navigate to “Reset to factory default”.
4. Click on the button once and confirm with the “Yes” button.

Your TV will reboot during the process once again. Make sure to wait it out and check on the sound once it boots up again.
