There’s no audio from your Toshiba TV, but video streams fine, making you wonder where the problem is.
You’re not alone!
The no sound issue is very common not only in Toshiba but for other brands like Samsung, Hitachi, LG, Sharp, and Sony.
It can have various causes, such as your TV hardware, settings, cables, external devices, or the provider.
Whatever the case, we’ve come up with practical solutions to help you diagnose and solve your issue of a Toshiba TV with no sound.
Read on to get familiar with them.
Toshiba TV With No Sound (Causes, Fixes)
1. Double-Check The Mute Status
As ridiculous as it seems, the mute feature is a common cause of Toshiba TV with no sound error.
People usually skip this check because they’re sure they haven’t enabled the mute mode.
Couldn’t it be your roomie or a visiting friend?
Don’t you have a pet that has accidentally stepped on your remote control, pressing the Mute key?
Just press the Mute button on your remote control to see if the sound comes back.
2. Turn Up The Volume
Just like the Mute button, your volume key may be accidentally touched and decreased all the way down to zero.
Ensure you haven’t faced such a blunder.
Note: Check the volume level and mute mode on your TV converters or set-top box, too.
They have similar settings that can obstruct your audio.
3. Try Other Channels
Sometimes, the problem lies neither on your end nor the TV’s or the Cable Box.
It could just be a transmission error from the broadcast station.
To check, try different channels and see if the sound restores in any of those.
If so, wait until that specific TV station resolves the issue.
4. Disconnect Output Devices
Your TV’s internal soundbar usually becomes dumb when you insert an audio output like a headset or speaker into the television.
Scan your output ports for any connected devices: AUX, RCA Stereo, Digital Coax, SCART, VGA Optical, etc.
Also, check for any wireless connected gadgets.
Then disconnect everything and see if the audio comes back.
5. Test Your Speakers
If using the television soundbar, attach a spare speaker to your TV and test the audio.
If you’re using an external audio system rather than your TV’s built-in speakers, hook them up to another device to see if they work correctly.
Alternatively, you can disconnect the audio system from your television and insert a pair of headphones into the headphone jack.
If you still can’t hear a thing, the issue lies within your system, not the speakers.
If the headphones successfully produce sound, you should call a repairman to fix the issue or buy an extra pair of speakers.
6. Turn On the Internal Speakers
Some Toshiba TVs give you an option to turn your built-in speakers on/off.
This allows users who set up a home theater to shut off their ordinary TV speakers, so the produced sounds won’t mix up.
Another possible reason for your Toshiba sound issue is that you’ve enabled this option by mistake.
- Just grab your remote control and go to the Main Menu.
- Select the “Audio” option.
- Choose “Speakers” and press the Enter button to set it to “On” status.
7. Connect To A Bluetooth Speaker
If you’re still unable to puzzle out the problem, try with a Bluetooth speaker.
This helps you recognize if the issue stems from the connection means—e.g., cables and ports—or a more serious one.
It also helps you narrow down our suggested solutions and restore your Toshiba TV sound sooner.
If your Toshiba model does support Bluetooth connectivity, proceed to the following steps.
However, if it doesn’t, use a USB Bluetooth dongle and pair your loudspeakers with it.
It’s an adapter that plugs into your Toshiba’s USB port, adding Bluetooth functionality to it.
- Make sure the Bluetooth function is on.
- Grab your Toshiba remote control and press the Home button to open the main menu.
- Navigate to Settings and select “Controllers and Bluetooth devices” from there.
- Go to “Other Bluetooth Devices”
- Let the TV discover your speakers and once it does, click to pair it.
- Play something and see if you can hear anything from the wireless speakers.
8. Disable Secondary Audio Protocol
SAP or Secondary Audio Protocol is a feature designed for non-native cable television users.
Through this stream, some TV stations provide an auxiliary audio track to their non-English audience to watch the same channels with their own language.
Not all broadcasters provide this service, and as a result, your TV stops producing any sound when you turn on SAP.
See if you’ve accidentally switched this on.
The method may vary depending on your Toshiba model but following these steps will probably make a go of it:
- First, look for an SAP button on your remote control to turn it off. (It may also be labeled as MS or AUDIO.)
- If there isn’t any, head to your TV’s Main Menu or Settings.
- Visit the Sound Options, and toggle the MS, SAP, or AUDIO option from “on” to the “off” position.
- If you don’t see an on/off SAP option, look for something labeled as “MTS” and change it to “Stereo,” “Mono,” or any other station on the list.
- If you’re still unable to spot the Secondary Audio Protocol, consult your user manual for more exact instructions.
9. Investigate The Wires
Cables are the main tools for data transmission, so any issue that interferes with their function can wreak havoc on what you receive on the television.
First, ensure the HDMI cable is firmly attached to both ends: your TV and the source device.
If you’re using an A/V cable, check that, too, and ensure you’ve inserted it into the correct port.
Then, inspect the wires for any cuts or signs of wear-and-tear.
If everything seems right, unplug all the cables, wait a few minutes, and re-plug them.
This will drain their power, clear the short-term memory, and finally reset their connection.
Also, check if you’re connected via an S-video cable.
These cables only support video signals, so if you want to receive audio, you’ll need a separate audio cable.
If everything fails, replace each of the cables with a new one to see if they’ve lost their connections.
10. Change Your TV Input
With an improper input setting, your TV won’t receive all or some part of the source signals.
You may see the pictures but miss out on the audio.
Think of a scenario where you’re connected to a satellite box but selected AUX as an input mode for your system.
This way, your TV tries to receive data from a source that doesn’t exist.
Change your input to DVD, AUX, Sat, Netflix, or Cable network, depending on what you rely on.
Then check if the issue disappears.
11. Reboot Your Television
Restarting is a one-size-fits-all solution for all electrical gear.
That’s because doing so flushes out the cache, bugs, and logical errors.
It also unlocks your TV processor, breathing new life into the whole system.
Turn off your TV, remove it from the outlet, and wait for at least a minute.
Then re-plug the device before you hit the Start button and re-initialize the system.
Hopefully, this will fix your Toshiba TV with no sound issue.
12. Alter Some Configurations
- Press the “Menu” or “Home” button through the remote control.
- Then, visit Settings and select “Display and Sounds” from there.
- Navigate to “Audio Output” and then “Digital audio format.”
- Under the “Audio format” header, choose “PCM” or “Stereo” as your desired format.
- Now, press the Back button until you reach the “Display and Sounds” screen.
- This time, go to “Sound Settings” and select “Advanced Settings” from the right pane.
- Scroll down to the “DTS” option and click so that it reads, “off.”
13. Factory Reset The TV
If the above modifications couldn’t bring audio back, you still get the chance to rectify your TV settings by recovering its factory defaults.
Look for the “More” or “Menu” button on the sides, back, or under your TV panel.
Then press and hold it for at least ten seconds to enter the ”Restore” window.
Then go with the on-screen prompts to complete and verify your request.
Here’s also an alternative method:
- Select the “Home” or “Menu” button on your remote control.
- Then, open Settings and scroll right to the “Device and software” section.
- Navigate to “Reset to factory defaults.”
- Press “Yes” to confirm.
Note: Study your television’s user manual for better directions since the path may vary a bit depending on your device model.
14. Upgrade Your Toshiba Firmware
Firmware upgrades can rectify a wide range of issues.
For one thing, they can enhance your HDMI compatibility, making your digital data convert more efficiently.
They also fix bugs, improving your TV functionality.
If the sound glitch results from a change in your broadcast system, it also makes your TV compatible with their service, so you’ll experience all aspects of a channel.
To automatically update your Toshiba smart TV:
- Connect your TV to a working WiFi.
- Use your remote control to visit the “Home” menu and open “Settings.”
- Navigate to the “About” section.
- Select System Update from the top.
- Proceed with the on-screen instructions to complete the updating process.
To manually update your Toshiba smart TV:
- Discover your device name and number through the main menu, and write it down (choose Menu > Get Help > Support Information).
- Then, open your computer browser, and visit the manufacturer’s download page.
- Type your Toshiba model into the search field, so it gives you the latest firmware. (Make sure to enter the name correctly, or otherwise, you may render your TV inoperable).
- Download the given files, unzip them, and then move to an external flash drive.
- Now, turn off your TV and disconnect it from the power outlet.
- Insert the storage before you re-plug and restart the television.
- This will take you to a blue screen that reads, “Upgrade in Progress.”
- Let the television do the rest, and don’t forget to restart it after the procedure completes.
15. Evaluate The Signal Strength
Both video and audio should have a signal level of 20 dB or higher to perform smoothly on your TV.
However, some logical issues can affect your signal strength, hence distorting its sound and image.
To sort out this issue, monitor your signal information on your device:
- Choose Settings through the main menu and go to “Support.”
- Click the “Self-diagnosis” header and then “Signal Information.”
- See if it’s significantly lower than 20 dB.
16. Dead Motherboard
When your TV’s motherboard fails for one reason or another, one consequence is that your inputs start to malfunction.
You won’t receive signals from your peripherals, such as cable box, disc player, PlayStation, sat box, etc.
Unfortunately, the motherboard is one of the most expensive and challenging parts of a TV to repair.
That’s because it houses all the essential components like power supply, controller, etc.
In most cases, buying a new TV will cost you less.
Call a professional and consult them before you invest in new equipment.
17. Google Chromecast
Sometimes, your mainboard isn’t faulty, but an external device like your Google Chromecast is making it overhear.
As a result, your TV starts acting awkward, and some of your television’s features won’t work as intended.
Here are a few things to check and modify with your Chromecast:
- Swap between the ports: Insert your Chromecast into a different outlet or a different USB port to ensure there are no connection or power supply issues.
- Tweak the Google Home App: Grab your smartphone and launch Chromecast’s dedicated app and tweak some settings. First, go to the app settings by pressing the gear icon at the top-right corner. Then select “More” and find the “Reboot” option. If it didn’t work out the sound problem, press the Up button on your mobile’s volume rocker to ensure your phone isn’t bottlenecking the audio.
- Force Stop the Google Home: Go to your mobile Settings and find the “Apps” section. Scroll down until you spot Google Home, select it, and press “Force Stop.”
18. What If You’re Using Chromecast Audio?
If you’re using the Chromecast Audio version, there’s another setting you can alter to sort out your Toshiba TV with no sound glitch.
Go to the app settings and look for an option labeled as “Sounds.”
Then, navigate through the items to find “full dynamic range” and switch it off.NEXT: Do You Need PS Plus To Play Minecraft? (Everything To Know)
