Sound issues are typically common on TCL Roku TVs.
This issue arises due to different factors, but usually, a simple power reboot can rectify it in 90% of cases.
Yet, sometimes, just rebooting the TV may not suffice, and you have to resort to complex troubleshooting.
However, In this article, I will break down why your TCL TV no Sound, when it may stop working, and what you have to do to get it back working again.
Here we go! Let’s dive into it…
Understanding why TCL TV no Sound
TCL TV’s sound can stop working if the audio settings are misconfigured, the volume is muted, the cables or connections are faulty, the speakers are malfunctioning, or there is a software issue in the TV.
Anything could trigger this issue!
If the issue is caused by a glitch, just a simple reboot is enough. But often you need to make changes in the settings or reset the whole sound settings in the TV.
In general, the following are the culprits:
- Wrong sound settings or cable connection.
- malfunctioning speaker.
- TV’s software glitch or firmware issue.
- TV’s hardware failure.
How to Fix TCL Roku TV no Sound Issue
- Disconnect the TV from the power outlet completely.
- Similarly disconnect all the HDMI and Audio cables from the TV.
- Wait for at least 5 minutes.
- During this time, press and hold the TV’s power button for about 30 seconds.
- Once done, power the TV back on and test the result.
Here’s the detailed guideline:
Step 1: Check the TV’s sound settings
Start by checking your TV’s volume settings, whether you turned it down or mistakenly pressed the mute button on your Remote.
I know it sounds silly, but sometimes just making sure your TV isn’t muted or set to a very low volume can solve the problem. Because People tend to overlook the obvious.
Also check the volume on other connected devices (if you use set-top boxes, external speakers, soundbars, and gaming systems.) These may have their separate volume controls, such as a remote or physical knob.
Step 2: check the cable connection
Depending on which device you use (whether it’s a speaker or soundbars) you’ll likely see different cords coming out of the back of your TV, and maybe one of them could be affecting your audio.
Cables are vital for sending sound and video. In some cases, a malfunctioning or old cable cause a bunch of issue,s and who knows, this could be the culprit for your TCL TV’s audio issue.
So, make sure the cables (whether it’s HDMI or speakers cord) are undamaged and securely plugged into the correct inputs. Remember that HDMI 1.0 inputs can only support 1080p and lower resolutions, not all high-definition formats.
While checking the cable, it’s a good idea to unplug and replug them. This will help to secure the connection from gunk accumulation and make the input ports more stable.
If you notice any damage sign in the cable, replace it with a new one and then check again.
Step 3: Try changing the content you are watching
It’s likely that the TV source/program you’re watching is having issues, whether it’s an over-the-air broadcast, cable or satellite service, DVD or Blu-ray player, DVR, gaming console, or apps (streaming channels).
Change the TV channel, input, or app to see if the issue is only with what you’re currently watching. I mean, if you are watching a show on Hulu and its sound isn’t working, try moving to Netflix and see if it works.
Step 4: Reboot the TV
Fear not, it’s just a simple thing. At the beginning of this article, I defined ‘software glitch’ as a major reason for the sound issues.
Almost 90% of smart TV users claimed that a simple reboot fixed their TV’s minor issues like lagging, freezing, or audio issue.
So, rebooting is worth of try, and here’s how to force reboot your TV:
- Turn off your TV and unplug it from the power source.
- Then press and hold the power button (not the reset button) for about 30 seconds.
- Finally, plug it back in.
Now check whether your problem has been fixed. If not, proceed to the next step.
Note: If your TV’s firmware/software is outdated and an update is available, update it now. Because outdated software can also cause this audio issue. Here’s how to update your TCL Roku TV.
Step 5: Factory reset the TV
Some online guides suggest changing the TV’s audio settings. But I don’t think it’s necessary. There is an easy way to restore your TV to its default state and hopefully, it can resolve your TCL Roku TV’s audio issue.
Yes, I am talking about ‘factory reset. You know how effective it is in recovering a device from corrupted or firmware malfunctioning. If you reset your TV, chances are that you may find your TV’s sound working again.
Thankfully, we covered this article before with a step-by-step guide on how you can reset your TCL Roku TV. Click on this link.
Remember that a factory reset will erase all of your previous settings and revert them to the default state as brand new. So, make sure you keep noting your important things.
Step 6: Check the speaker
If none of the above-mentioned troubleshooting steps help you fix the issue, your TV’s external or internal speaker has been damaged.
To ensure, try connecting a different speaker to your TV. If it works, you must replace your TV’s internal speaker. But if not, visit your nearest TV repair shop.
Creative hack to bypass sound issue
Once you have verified that the TV’s internal speaker or audio processing circuitry is flawed, you could consider trying innovative fixes such as using a Bluetooth speaker.
This comes in handy If your TV’s internal speaker is not working or is somehow damaged. Because It will 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.
