Hisense TV no sound – how to fix and possible causes

The first thing you can try in this case is to make sure that your TV is not set on ‘mute’ or on a very low volume. 

Here’s what you can do – 

• Press the mute button to check if the TV is muted or not
• Try increasing the volume
• If you think the volume buttons on the remote are not working, try the buttons on the TV
• You can also use smartphone remote apps to increase the volume 

If tinkering with the volume levels is not working, then you can try changing the sound mode. Sometimes, if the sound mode is not selected correctly for the content you’re watching, then it might deteriorate the sound quality. 

Here’s how to change the sound mode on Hisense TV – 

• Head over to ‘Settings’ menu
• Find and click open the “Sound” option
• Select sound mode, and you will see a list of sound modes 
• Try choosing different modes and check the sound
• If it works, you can select a mode and exit the menu

If you have external speakers or soundbars connected to your TV, you can choose whether you want your audio to be played via the TV speakers or the peripherals. Sometimes, you might end up choosing the wrong output.

• See if the right audio output is selected
• Check if the output you have selected is turned on (for instance, if you have chosen external speakers, see if they’re turned on and working)
• See if the peripherals are connected properly to the TV

Sometimes if you tinker a bit too much with the audio settings, you might end up messing up the audio setup. If you think this is the case, then the best way to resolve it is to set the audio settings back to default.

If your Hisense TV’s firmware has not been updated in a while, then it is likely that some bugs in your TV haven’t been fixed. 

Here’s a general idea of how to update your Hisense TV – 

• Go to Settings from the home screen
• Head over to Device Preferences
• Locate and click open the About section
• Click on System Update
• Your TV will scan for available updates
• If there’s an update available, install it

After the firmware update is installed, check your TV for sound.

Please note that the exact process of updating your TV will depend on the model you have. For more details, check our guide on how to update Hisense TV. 

If you’re using external speakers or soundbars, then you should check whether they are properly connected to the TV. If the cables are loosely connected, then the sound system won’t work. Also, check for any damage to these cables, like fraying, and consider replacing them.

Usually, power cycling solves minor glitches, so it’s worth trying it out for the no sound issue.

Here’s how to power cycle your Hisense TV –

• Turn your TV off
• Unplug it from the wall outlet
• Wait for a minute
• Plug it back in
• Turn it on

Check if the audio works.

If the troubleshooting tips here do not work, then you can try factory resetting your Hisense TV. Note that a factory reset will delete all your settings 

• Go to Settings
• Look for ‘System’ or ‘Advanced Settings’
• Then, find and select the ‘Factory Data Reset’ or ‘Reset’ option
• Some Hisense TVs have two options – Reset TV Audio/Picture Settings’ and ‘Factory data reset’ – you can choose the one you prefer
• You might be prompted to enter a 4-digit code
• The TV will be reset after you confirm the action

When the TV restarts, check if the audio is working.

The exact process for resetting your Hisense TV will depend on your model. For more information, you can check out our guide on How to reset your Hisense TV.

If nothing seems to be working, then it’s time to get in touch with the Hisense support team, especially if you think the TV speakers are the culprit.
