What Hisense TV has no sound?
The sound on your Hisense TV won’t work for many reasons. Isolating the exact reason behind the problem is a little tricky.
Below are the common reasons why your Hisense TV has no sound:
- Volume is set too low: Many people accidentally set the volume too low or mute and wonder why the TV does not have sound.
- A glitch: A glitch or bug may make Hisense TV sound not work. Bugs are relatively common on all TVs, including Hisense TVs.
- Misconfigured sound settings: Incorrectly set sound settings can end up causing sound problems on your TV.
- Cable not connected properly: If you have connected external speakers to your TV, a loose connection could be a probable reason why your TV has no sound.
- TV’s internal speaker is faulty: If the internal speaker of the TV is faulty, the sound won’t work. You can confirm this by connecting an external speaker or a Bluetooth speaker.
How to fix Hisense TV when it does not have sound?
If your Hisense TV does not have sound, first, make sure the TV is not muted or the volume is set too low. Next, power cycle the TV by unplugging it and pressing and holding the power button for 20 to 30 seconds.
Ensure the TV is not muted or the volume is too low
The first thing you must check when your Hisense TV has no sound is whether the TV is muted or the volume is set to low.
People accidentally mute their Hisense TV and wonder why the TV does not have sound.
People unknowingly sit on top of the TV remote, or the remote slips through the crevices of the couch and may mute the TV.
See if you can find a speaker icon with an x or cross mark on the TV screen. If yes, it means the TV is muted.
Press the Mute button on the remote to unmute.
Similarly, if you set the volume too low, the sound won’t work. Grab your Hisense TV remote, press the volume up button several times, and see if it helps.
If your TV is connected to a set-top box, Blu-ray player, or any such devices, grab the remote of that specific device, make sure it is not muted, and press the volume up button a couple of times to increase the volume.
If your TV is not muted and the volume is not set too low, it could be due to a software bug.
Soft reboot the TV
Simple software glitches on your Hisense TV can be easily fixed by performing a power cycle a.k.a. soft reboot. It helps to eliminate bugs by completely turning the TV off and on again.
Power cycling drains piled up static charges on the TV.
Firstly, unplug your Hisense TV from the wall outlet.
Locate the power button and press and hold it for 20 to 30 seconds.
Wait for a minute or two.
Plug the TV back in and press the power button to turn it on.
See if the sound works now.
Power cycling helps when your TV does not turn on or it keeps restarting.
Are you using an external speaker with your Hisense TV? Loose connections are yet another problem that causes sound issues on your Hisense TV.
For example, let’s say you have connected a sound bar or advanced speakers system to your Hisense TV. If the HDMI cable or the AUX cable is not correctly connected or the cable is faulty, your Hisense TV will not produce any sound.
So unplug the HDMI or AUX cable and plug it in again.
Ensure no dust or debris is built up on the port or cable.
Look for visible cable damage, like a cut, and make sure the cable is not frayed.
Additional tip: try restarting the sound bar or speakers system as It will help fix any simple glitches associated with them.
Tweak the sound settings
Switching the Hisense TV audio digital output to PCM mode has helped fix sound issues for many people.
Follow the steps below to see how to set digital output to PCM on your Hisense TV.
Select Device preferences.
Scroll down and select the Sound option.
Select the Digital Output option and set it to PCM.
After setting the digital output to PCM, see if your Hisense TV has sound.
Reset sound settings
If setting the digital output to PCM on your Hisense TV sound settings didn’t help fix the problem, let’s try resetting the entire sound settings.
People unknowingly play with sound settings on their TVs and configure it incorrectly. If you are not sure what exact settings you changed, the simple thing to do is to reset the sound settings.
Hisense Android TV:
On your Hisense TV, open Settings.
Select Device Preferences.
Scroll down and select the Reset to Default option.
A pop-up may appear asking you to confirm. Select Yes to continue.
Hisense Roku TV:
- Open Settings
- Select System
- Scroll down and select Advanced System Settings.
- Select Factory Reset.

Once you reset the sound settings, restart the TV and see if the sound works now.
Disconnect the external speaker
Is the problem with your TV or the external speaker connected to it?
Sometimes, the problem may not be with the Hisense TV but with the speaker attached to it.
Many people use external speaker systems instead of built-in TV speakers.
You need to disconnect the external speaker system to see if the problem is with the TV or the external speaker.
After disconnecting the external speaker, try playing some content on the TV and see if the sound works.
If your TV has sound after disconnecting the speaker, it means the external speaker has some problem.
On the other hand, if the sound does not work even after disconnecting the speakers, the issue is with the TV itself.
Connect an external speaker
The next thing is to check if the internal speaker of your TV is faulty. But how will you know it?
To see if the problem is with the TV’s built-in speaker, you may try connecting an external speaker, a headphone, or a Bluetooth speaker and see if the sound works.
If the TV has sound after connecting an external speaker or headphones, it means the built-in speaker is faulty.
Since it is a hardware problem, you must contact Hisense support and arrange a pickup and service.
You may also take your Hisense TV to an authorized service center and let a professional inspect and fix the problem.
If connecting an external speaker does not fix the problem, it might be a software issue.
