Possible Solutions to Fix Hisense TV No Sound Issue
The no-sound issue can be fixed by performing some easy fixes. Walk through the full guide chronologically to get to know them in detail. These troubleshooting methods will fix the Hisense TV no sound issue on models, including VIDAA, Roku, Google, Fire, Android, and XClass/Xumo TV.
Check Whether your TV is Muted
While this may be a simple fix, many of us put our TVs in mute mode unknowingly, and here is where the sound issue starts. To resolve this issue, check if your TV is fully muted or the TV volume is lowered. If muted, press the Mute button once to unmute the TV.
In case of low volume, press the Volume Up button on your remote TV to increase the volume. Once done, the Hisense TV no sound problem will be solved. If it doesn’t, move to the next troubleshooting method.
Power Cycle Hisense TV
A quick power cycle will be the best remedy to get any electronics out of the issue, including audio and video. Performing a simple restart on Hisense TVs will remove the temporary bugs and glitches at a basic level. To power cycle your Hisense TV,
- You must press the Power button and turn off your Hisense TV if it is turned on.
- After that, remove the power cables from the TV and wall socket.
- Leave the TV undisturbed for about a minute to drain out the power.
- Upon doing so, you need to plug the power cables back into the TV and then turn on the switch.
- Now, play any video and check if the TV delivers the audio properly.
Inspect the HDMI Cables
HDMI cables are known for high-quality video transmission and also for audio signals. If you are experiencing a sound issue on your TV, you must ensure that the HDMI cables are properly plugged into the TV without any loose connections. Suppose the connected cables are damaged, the sound might be distorted and they need to be replaced with a new one.
Once you have replaced the HDMI cables, play any media content along with audio and check if your Hisense TV is out of the no sound issue.
Check the Speakers
In rare scenarios, the Hisense TV speakers may get damaged or blocked by external objects. In these cases, you need to hire a technical team to fix the speakers or other audio systems.
Sometimes, external speakers may also not work efficiently if dust particles accumulate on them. So, if you have connected a soundbar to your Hisense TV, you must clean the device at regular intervals to avoid the Hisense TV no volume issues.
Verify the Audio Settings of the TV
Audio settings are one of the important aspects that cause Hisense TV sound problems while streaming Netflix, Prime Video, or other programs. To deliver seamless audio, you need to check whether the audio output settings on your Hisense TV are correctly set to the necessary ones. In case your TV is connected to external speakers like a soundbar or home theatre, ensure you switch the input on Hisense TV to the respective ones to get the sound output.
Change the Digital Output to PCM
Another reason for the Hisense TV’s lack of sound is the poor digital audio output configuration on your Hisense Smart TV. However, switching the digital output to PCM is the only way to get your TV out of the issue. To do this, you need to navigate to the Settings menu of your respective Hisense Smart TV and change the digital output to PCM.
As Hisense runs on various OS and each TV differs with its settings option, you need to perform this process carefully.
Verify the Bluetooth Devices
Sometimes, you’ve accidentally connected your Hisense TV to a Bluetooth speaker and left the speaker in mute mode. Also, there might be a possibility that you paired your Hisense TV with AirPods. So, inspect if your Hisense TV is connected to Bluetooth devices or not. If it does, disconnect your TV from the Bluetooth device and check whether the sound is hearable from the TV’s speakers. However, if it doesn’t, then move on to the next troubleshooting technique.
Update the Hisense TV Firmware
Outdated firmware also plays a vital role in the no-sound issue. To avoid such issues, you need to update the firmware of your Hisense TV at regular intervals whenever a new update arrives. If you don’t want to deal with manual updates, enable the auto-update option, and your TV firmware will automatically update whenever a new version is released.
Once your smart TV is updated to its latest software, play any content on the TV and check if the audio is delivered properly.
Reset Hisense TV
If nothing seems to work properly, then it’s time to restore your TV to its default settings. Unfortunately, resetting your Hisense TV will delete all the stored data and settings on the TV, but it can fix any sort of issue.
By performing the reset process, you can eliminate any hidden sound settings that cause the TV to malfunction abnormally. Once done with this process, you need to set up your Hisense Smart TV from scratch and customize the audio settings of your choice.
