1. Toshiba TV No Sound, But Good Picture

Your Toshiba TV sound not working, or no sound on your TV is one of the major volume-related problems. There may be video streaming on your TV, but there is no sound coming from it. 

If your Toshiba TV displays a good picture, but you are not getting any audio from it, that means your TV is not functioning correctly. The major factors behind it are:

i. TV Is Muted

Without any sound error, your Toshiba TV may stop generating audio because your TV’s Mute feature is on. You may unintentionally and accidentally press the Mute key by stepping on your TV remote.

When you experience your Toshiba TV sound not working, you should double check your TV remote’s Mute button. Press the mute button to unmute your TV.

ii. Lower Volume Of TV

Accidentally your TV remote’s volume button becomes touched, and the sound becomes reduced directly to zero. This is another factor responsible for your Toshiba Television sound problems.


Check your Toshiba TV’s volume level and increase it all the way from zero.

iii. TV Channel Experiencing Problems

When a particular channel experiences network-related glitches, it may stop producing sound.

The broadcast station fails to transmit a signal and sends an error. As a result, the TV stations fail to receive signals and stop making a sound.


Check the broadcast station’s transmission error by trying a different channel. The other channel will function correctly if a single station is not producing sound due to the signal error.

So, check other channels or stations to see whether the channel has been restored or not.

iv. TV Connected With Output Device

If you connect your Toshiba TV with different output devices such as headphones, your TV’s internal soundbar will automatically stop producing sound.

Whether you connect your TV with output devices’ or wireless gadgets, your TV’s inner sound will stop working.


Correctly connect your Toshiba TV’s ports to scan the output devices, such as RCA Stereo, AUX, SCART, Digital Coax, VGA Optical, etc.

Also, look for a wireless gadget connection with your TV. Finally, disconnect all the output devices and wireless connections, and your TV’s audio will start functioning.

v. TV’s Defective In-Built Speakers

Your Toshiba TV sound is not working because the TV’s in-built speakers are not functioning correctly. TV speaker pairs stop operating mainly for the following reasons:

  • Damaged, broken, or defective in-built TV speakers
  • The TV speaker’s internal components are not working or damaged internal parts
  • Aged speakers
  • Speakers loose wire connection


Test your TV’s in-built sound speaker audio by attaching your TV to a spare speaker. Disconnect your TV’s audio system and insert the headphones to check the speakers. If the faulty speaker is creating sound trouble, solve it in the following ways:

  • Replace the malfunctioning, broken, or damaged in-built TV speakers, old speakers, and faulty internal parts
  • Check and tighten your TV speaker’s wire connection

vi. Malfunctioning External Speakers

If your TV is connected to any external speakers system for producing louder volume, it won’t make a sound due to the speaker’s malfunction. TV’s external speakers become faulty for the following reasons:

  • Incorrectly configured sound settings
  • External speakers and TV are not correctly connected
  • Broken, damaged, or loose cable connection
  • Defective devices such as DVD players, receivers, or gaming console
  • Dirty external speakers


If the faulty external speakers are causing Toshiba TV intermittent sound problems, you should follow the fixing ways below:

  • Correctly configure your TV’s sound settings
  • Ensure your Toshiba TV and external speakers are properly connected
  • Replace the damaged HDMI cable and faulty external devices
  • Tighten your TV and external speakers cable connection and adequately clean the units

vii. TV’s Internal Speakers Set To Off

You can turn on or off the built-in speakers in your Toshiba smart TV. While setting up your TV or home theater, if you turn off your TV’s in-built speakers, it will produce no sound.

You may enable this feature by mistake and set the internal speakers off, so your TV stops producing sound.


Check your Toshiba TV’s built-in speaker’s on/off feature and make sure it is not turned off. If so, turn it on by following the steps below:

  • Take your TV’s remote and go to its Main Menu
  • Navigate to your TV’s Audio option
  • Select the Speakers option and turn the status to “ON” position

viii. Enabled Secondary Audio Protocol

For non-native Toshiba TV users, one of the features designed in the TV is its Secondary Audio Protocol or SAP.

Some TV channels offer their non-native English audience an auxiliary audio track through this stream. Thus, the non-English audience in their language can enjoy the same channels.

However, this service is unavailable to some broadcasters. As a result, if you turn on the SAP feature, your TV stops producing sound. Even if you don’t switch on this feature intentionally, you may turn it on accidentally.


Check your Toshiba TV’s SAP feature and disable it if it is turned on. Disable this feature by following the steps below:

  • Find out your TV remote control’s SAP button and turn it off. This button can be labeled as the Audio or MS button.
  • If this button is not available on your remote, then go to your TV’s Settings or Menu
  • Navigate to the Sound options and turn off the SAP, MS, or Audio option
  • The on/off option may not be available all the time. So you need to change the MTS labeled option to “Mono” or “Stereo.”
  • However, still, if you don’t find the SAP option, go through your Toshiba TV manual for more precise instructions

ix. TV Cable Malfunction

Mainly through the cable, your Toshiba TV transmits data. But the faulty cable fails to send a signal, and it causes no sound issue on your TV. The main accountable factors for it are:

tv cable malfunction
  • The HDMI cable is not firmly attached to your TV’s both ends (source device and TV)
  • Inserting the A/V cable into the wrong port
  • Worn out, damaged, broken, or loose cable
  • Only the S-video cable is connected to your TV
  • TV cable facing excessive heat
  • Electrical overloading


Check your Toshiba TV cables and make sure it is perfectly transforming signals. If the faulty wires are the culprit, unplug your TV’s cable connection and wait 2-3 minutes. Then re-plug the wires. 

This plugging and unplugging process will clear your TV’s short-term memory and drain the power by resetting the connection. The other solutions are:

  • Make sure the HDMI cable is firmly attached to your Toshiba TV’s both ends
  • Insert the A/V cable into the correct port
  • Replace the damaged, worn-out, broken, or loose cable
  • Ensure not only the S-video cable is connected to your TV
  • Make sure your TV’s HDMI cable is not facing excessive heat

x. Wrong TV Input Selection

Your Toshiba TV fails to receive a signal because of the improper or incorrect input setting. Choosing the wrong input source is one of the main reasons you experience missing out on audio on your TV, but the picture is visible.

If the satellite box is connected to your TV, but you select the AUX input mode, your TV will not get the correct signal. If the source doesn’t exist at all, your Toshiba TV will fail to receive data from the source.


Select the correct input source such as AUX, Netflix, DVD, SAT, or cable network, depending on which type of source is connected to your Toshiba TV. After selecting the correct input source, check whether the sound issue has disappeared or not.

xi. Faulty Main Board

Your TV’s sound input started malfunctioning due to the failed motherboard. The faulty main board fails to receive a signal from the disc player, cable box, sat box, Play station, etc. For the following reasons the main board goes bad: 

  • Faulty electrolytic capacitors 
  • Blown fuse 
  • Damaged or defective internal components 
  • Disconnected power cord or loose connection 
  • Power outage or improper DC voltage 


For solving the above troubles, the easy fixing ways are: 

xii. Muted External Speakers

Check the soundbar, home theater system, and external speakers, and make sure it is not muted. If it is muted or in a turned-off position, you should turn on these devices, and your Toshiba TV audio problem will disappear.

viii. Digital Audio Format Is Not Turned On

If you are using the digital optical cable for connecting the sound bar, home theater, and external speaker system to your Toshiba TV, you need to turn on this setting. Due to the turned-off digital audio format, your Toshiba TV stops producing sound.
