How to Troubleshoot Hisense TV Sound Not Working

With a few simple steps, you quickly fix a Hisense TV Sound Not Working problem in no time!

Here’s what to do:


1. Check if Speakers are Connected:

Check all the connections on the back of your TV and make sure all speakers are connected and turned on.

If any of them are not, then reconnect them and make sure they are firmly attached to the back of the TV.

Also, make sure none of the wires are loose or frayed.

2. Check Volume Level:

To do this, simply press the “up” and “down” keys on your TV remote. You should be able to hear a slight increase or decrease in volume when you push either button.

Also, ensure your TV’s volume is turned up as high as it will go. If it’s not, then try turning it up louder.

If it’s too loud, then try turning it down a notch or two.

3. Check Speaker Jack:

Remove the rubber cap from the headphone jack on the back of your TV.

Look inside the jack and see if any dirt, dust, or debris has gotten into the jack. Clean it out with a cotton swab or your fingers. If the debris is still in there, then remove it.

4. Inspect Ribbon Cable:

Check the ribbon cable connecting your TV to the audio/video input on the back of your satellite box or cable.

If there is any kink or damage to the cable, gently straighten it out.

Also, ensure that none of the connectors are broken or loose.

5. Clean Air Ventilation Holes:

Check all the ventilation holes on the back of your TV and make sure none of them are blocked.

If they are, use a cotton swab or your fingers to wipe them out gently.

Blocked ventilation holes can cause overheating and may be the reason why your TV sound is not working.

If your Hisense TV has no sound, the next thing to check is the speaker connectors.

Here is how:

  • If you have any speaker cables attached to the back of your TV, then disconnect them from the connectors on the back of the TV.
  • Next, unplug the connectors from the back of the speakers. Then, plug the connectors on the back of the speakers into the proper jack on the back of the TV.
  • Finally, reconnect the cable that was connected to the speakers.

7. Inspect Signal Cables:

Check all the signal cables attached to the back of your TV and make sure they are all plugged into their respective jacks.

Also, if there are any loose or damaged cables, then gently clean them out with a cotton swab or your fingers.

8. Check Antenna Input:

Make sure the antenna input on the back of your TV is clear of any obstructions.

Also, make sure the coaxial cable that goes into the antenna input on the back of your TV is securely attached to the back of the TV and not loose or damaged in any way.

9. Check Power Cord:

Make sure the end of your power cord is not kinked or damaged in any way. If it is, then gently straighten it out.

Also, double-check that none of the connectors are broken or loose.

10. Force Restarts your Hisense TV:

If all else fails, try forcing a restart of your Hisense TV.

To do this,

  • Turn off your TV.
  • Remove the battery from the back of your TV.
  • Wait a few seconds.
  • Then, replace the battery and turn your TV back on.
  • This should force your TV to reboot and may fix the sound problem.

11. Try a Different Audio/Video Source:

If all these steps do not work, try using another source like a DVD player, video game system, or radio.

If you still have no luck, then it’s time to call a repair person.

These troubleshooting steps should solve the sound problem. If this Hisense TV problem persists, you should take your television to a repair shop.

What are the Sources of Sound in a Hisense TV?

To summarize, sound just might be the most important element that you can find in a TV. It can make or break your experience with it.

Sound is also one of the sources of Hisense TVs. For TVs to achieve proper sound and ensure an immersive experience, they always come with multiple speakers and a powerful amplifier.

There are speakers at the back and top of the TVs, while the amplifier placement is on the bottom.

The speakers need power from an AC outlet, which the TV utilizes to power up the amp and provides signals for processing audio and video signals.

What’s more, the TV has a subwoofer, which is a small bass speaker, and its placement is at the bottom part of the cabinet.

All these components work together to provide you with the best sound experience possible.

What is the Difference Between Speakers and Surrounds? Hisense TVs come with two types of speakers:

  1. Front Speaker/Center Channel: This is the most common type of speaker that you will notice on most TVs. It has a single diaphragm and is responsible for delivering mid-range and high frequencies.
  2. Surround Speakers: Surround speakers are usually smaller than the front ones and are used for reproducing low frequencies. They are used to enhance the bass effect of the TV. Hisense also offers a Surround mode that allows you to connect up.

  1. We have a Hisense TV Model 40H4030F1, the tv works good but sometimes the sound quits. When the sound quits, we restart the tv and the sound works again. Sometimes it stays working and sometimes it quits and have to restart again. Any suggestions?

    • Hello Patti,

      You can check to see if your device is plugged into a power source and the TV is on and if it is not, plug it in and turn on your TV.
      The TV’s sound settings are controlled by the TV’s internal system. You’ll need to check your TV manual for the correct settings.
