Hisense TV no Sound Troubleshooting Guide

Sound issues are typically common in Hisense TVs. Let me tell you about my own experience.

Yesterday, my wife (Adiba Islam) and I planned to watch our favorite show Game of Thrones (2011-2019) at night. We completed all of our preparations, and she took a bowl of popcorn. Then, we sat on the sofa comfortably.

Guess what happened next? We experienced the same thing that you might be experiencing right now – there was no sound, just the picture. This ruined our plans. (Blastade Technology!)

However, I immediately performed some basic troubleshooting, and even though I’m not a DIYer, it wonderfully worked for me. The issue was a temporary glitch and was solved by a simple power reboot.

But, it may not work for you. In this article, I will explain why and when you may face this kind of stupid issue, and what you need to do to troubleshoot it.

Understanding when and why the Hisense TV’s sound may stop working.

reasons why sound not working on hisense tv

Several reasons exist for the sound issue on Hisense TV. But a temporary system glitch, or outdated system firmware is the main culprit. Aside from this, issues with audio processing circuitry or the audio decoder may also be responsible.

However, here’s a list of some potential reasons:

  • Wrong audio output settings.
  • Temporary system glitch.
  • Audio processing issues.
  • Speaker problems.
  • Outdated firmware.

Troubleshooting a Hisense TV that has no sound

In short: To troubleshoot if your Hisense TV has no sound, first do a power reset. Disconnect the TV from the power outlet, and wait a minimum of 60-80 seconds. During this time, press and hold the power button for about 20 seconds. Once done, replug the TV.

Before moving into step-by-step instructions, look at the bellow table. This will make it easier to understand this article quickly.

Reason for sound issues Potential solution
Audio output settings Check the TV’s audio output settings and ensure they are set to the appropriate mode
Loose or faulty audio cables Check the audio cable connections and try replacing them if necessary
Audio processing issues Try restarting the TV, resetting the audio settings, or updating the TV’s software
Speaker problems Check the speakers for damage or defects and repair or replace them if necessary
Software updates Check for software updates and install the latest version
Audio source issues Check the audio source for problems and ensure it is sending an audio signal

Step 1: Do a basic check

Checking the volume label, changing the audio settings, or rebooting the TV are almost the basic troubleshooting steps that people generally do as the initial steps. I think you have already done so.

However, there may be some steps that you might don’t know about.

  • Restart the TV: Often, a power reboot is all it takes, and this works in about 90% of cases. I personally had success with this method: turn off the TV and unplug it from the power source for a few minutes, then plug it back in and turn it on again.
  • Check the audio output settings: If you have external speakers connected to your TV, make sure that the TV is set to output audio to the correct output device. You will find this in the TV’s audio settings menu.
  • Audio source issues: If the audio source, such as a cable box, streaming device, or DVD player, is not sending a proper signal, sound issues is mandatory. Check the source device if it is faulty.
  • Check the HDMI connection: Though HDMI connection is primarily used for video signals, it also carries audio signals. So, HDMI connections can potentially cause sound issues on a Hisense TV if the audio signal is not being transmitted correctly. Check the HDMI cable for damage, loose connections, or proper insertion. If necessary, try replacing the HDMI cable.
  • Reset the Audio settings:  Go to Settings > Device Preferences > Sound, then click on Reset to Default. Fear not, this will not delete anything.

Step 2: Deep troubleshooting

Sometimes, sound can stop working due to a virus/malware infection or an issue with the system firmware. If basic troubleshooting doesn’t solve the issue, do the following things.

♦ Update the firmware

Hisense releases regular system updates to improve overall functionality and eliminate bugs. When an update is released, TVs automatically catch it.

But if yours failed to do so, various problems could arise like the TV not turning on or the remote not functioning. And the sound issue is common. So, before factory resetting, check if there is any update available.

Here’s how:

  • Press the “Home” button on your Hisense TV remote.
  • Select “Settings” and then “System“.
  • Choose “System Update” and select “Check Now“.
  • If there is an update, select “Download” to begin the process.

That’s it! Once the update is downloaded, your Hisense TV will automatically install it and restart.

♦ Factory Reset the TV

If there is no available update, consider doing a factory reset as the final solution. This will essentially erase any corrupted code and return the TV to its original settings.

That’s logic, of why you have to reset the TV. Hopefully, a factory reset may help you.

Keep in mind that resetting the TV will erase all installed apps and your customizations, as well as other data.

  • Press the “Menu” button on the remote control.
  • Go to “Settings” and then “System“.
  • Select “Factory Reset” and press “Enter“.
  • Enter the password, if prompted. (The default password is usually “0000” or “1234”).
  • Select “Yes” to confirm the reset and press “Enter“.
  • Wait for the TV to reset and restart.

After the reset, the TV will be restored to its default settings and all your customizations, installed apps, and saved data will be erased.

Step 3: Out-of-the-box solutions

out of the box solutions for hisense tv that has no sound

Let’s say, you ensured that the TV’s internal speaker or the audio processing circuitry is faulty. In this case, you can try some creative hacks like using a Bluetooth speaker or an external audio decoder.

Remember: these may require additional equipment or expertise to implement. So ensure that you have the necessary tools and knowledge before attempting them.

♦ Use a Bluetooth speaker

This method comes in handy If your TV’s internal speaker is not working or is somehow damaged. It involves connecting a Bluetooth speaker to get direct audio output instead of relying on the TV’s internal speakers.

It will, however, require you to purchase an additional speaker/subwoofer, which may cost between 99$ to 200$. You can use any model but be sure it has Bluetooth compatibility.

♦ Use an external audio decoder

This is basically useful when the TV’s speaker is good but the audio processing unit is faulty.

This is because it takes the audio signal from the source device and decodes it into analog. Which then deliver to the external sound systems.

However, it requires additional equipment and is more complicated to set up than other solutions.


Q: Can a faulty HDMI cable cause sound issues on a Hisense TV?

Yes, a faulty HDMI cable can cause sound issues on a Hisense TV. Check the HDMI cable and make sure it is properly connected and not damaged.

Q: How can I connect an external sound system or speakers to my Hisense TV?

You can connect an external sound system or speakers to your Hisense TV by using a compatible cable, such as an HDMI cable or Bluetooth connection.

You will need to connect the cable to the TV’s audio output and the input on the sound system or speakers.

Q: Is it safe to try to repair the internal audio system of a Hisense TV by myself? 

No, it is not safe to try to repair the internal audio system of a Hisense TV by yourself. This could cause damage to the TV or harm to yourself.

You should contact a professional technician or customer support for assistance.
