Q-1) “Homespoiler, last night while streaming shows from my Laptop to TV, I experienced a strange issue. My Hisense TV’s sound wasn’t working, I mean as soon as I connect my Laptop to TV, sound stops working. But TV alone is working fine.”—Jemol Jackson, Washington DC
Q-2) “Hello Homespoiler, you guys are doing great. For the last few days, we having no sound issue on our Hisense TV. Before you tell me the sound speaker is damaged, I want to inform you that we use an external speaker from JBL and also our TV is brand new. What could be the issue?”—Herid Floker, Newyourk
Sorry to hear this!
First note, —‘Sound issues are typically common‘ not only in Hisense TV but also in other top brands like LG or Samsung.
But the Issues both of you described seem a bit complicated.
However, I will break down these issues one by one and also provide you with some potential solutions to get back your TV working again.
Here we go! Let’s dive into it…
Why Hisense TV has no sound?
Several reasons exist for the sound issues on a Hisense TV.
Common causes of sound issues on a Hisense TV include temporary system glitches, outdated system firmware, and problems with audio processing circuitry or the audio decoder.
In Jemol’s case, the issue might be with the laptop’s audio output settings, while in Floker’s case, the problem could be related to either the TV’s audio settings or a firmware issue.
Here is a list of some general reasons for sound issues:
- Wrong audio output settings.
- Temporary system glitches.
- Audio processing issues.
- Speaker problems.
- Outdated firmware.
How to troubleshoot a Hisense TV with no sound
To troubleshoot a Hisense TV with no sound, try performing a power reset. Disconnect the TV from the power outlet for 60-80 seconds, then press and hold the power button for about 20 seconds. Finally, plug the TV back in.
Here are the detailed solutions from basic to advanced.
Step 1: Do some basic check
Checking the volume label, changing the audio settings, or rebooting the TV are usually the basic troubleshooting steps that people generally take as initial steps.
However, I believe you have already done these.
Nevertheless, there may be additional steps that you might not be aware of.
- Change the audio output: If you are streaming from your laptop through HDMI cable, change the laptop’s audio output settings to route the audio to the Hisense TV.
- 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.
- Check the HDMI connection: Though HDMI connection is primarily used for video signals, it also carries audio signals. Therefore, 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 stops working due to a virus/malware infection or an issue with the system firmware. If basic troubleshooting doesn’t solve the issue, try the following steps.
♦ Update the firmware
Hisense releases regular system updates to improve overall functionality and eliminate bugs. When an update is released, TVs automatically catch it.
So, before factory resetting, check if there is any update available.
- 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 the 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
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.
