TCL Soundbar Troubleshooting: How to Fix Common Audio Problems
TCL Soundbars and Common Issues
TCL originally burst onto the home theater scene as a budget TV alternative to big-name brands like Sony, Samsung, and LG. The quality of these TCL TVs has steadily improved over the years, causing their popularity to soar as they began to rival the competition at a cheaper price point.
To complete its home theater package, TCL developed a lineup of soundbars—ranging from a simple, single-bar setup to a full surround setup featuring a bar, subwoofer, and rear speakers. Like their TV counterparts, these soundbar systems have competed against some of the best soundbars available today.
Despite the brand’s dedication to quality, TCL’s soundbars can run into the same common issues that accompany many soundbar systems. Some of these problems include:
-
Audio cutting in and out
-
A subwoofer or rear speaker not fully working
-
The soundbar itself not delivering any audio
While frustrating, there’s usually a simple fix at the heart of these routine issues.
Issue 1: The Soundbar Has No Sound
Most modern TVs automatically send audio signals to a connected soundbar, especially when connected via HDMI ARC or eARC. So, after setting up a new soundbar system, one of the most numbing experiences is to power on your TV and hear… nothing.
Sometimes there’s a clear indication that something is wrong, such as a flashing light on the soundbar. It’s a common problem that can happen to any soundbar brand, not just TCL. More often than not, it’s tied to a connection issue or an audio setting that doesn’t match for both the TV and soundbar.
How to Fix It
| Step | Action |
|---|---|
| 1 | Check your connections. If using HDMI ARC/eARC, make sure the HDMI cable is connected to the correct ports on both devices. |
| 2 | Verify the soundbar’s input is correct. Most TCL soundbars have dedicated inputs for HDMI, optical, and Bluetooth. |
| 3 | Ensure the soundbar is set to the cable or connection you’re utilizing. |
| 4 | Adjust your TV’s audio settings. Find the TV’s sound settings and toggle its Audio Output setting to either external speakers, HDMI ARC, or optical. |
Pro Tip: The exact steps for changing audio output vary depending on your TV brand, but the setting is usually found under Sound or Audio in the TV’s settings menu.
Issue 2: Audio Is Cutting In and Out
If you are getting audio from your new TCL soundbar, another common issue is experiencing the bar’s sound randomly cutting in and out. This issue can be mind-numbing because it may not follow a pattern—you may get a solid episode of TV in without any hiccups, then be plagued by it the next time you stream something.
The Most Likely Culprit: Your Connection
| Connection Type | Susceptibility to Interference |
|---|---|
| Bluetooth | ⚠️ High—most susceptible to signal interference |
| HDMI ARC/eARC | ✅ Low—stable, wired connection |
| Optical | ✅ Low—stable, wired connection |
How to Fix It
| Step | Action |
|---|---|
| 1 | If using Bluetooth, switch to a hard-wired connection like HDMI or optical. |
| 2 | If already using HDMI or optical, check that the cables are fully secured into both the soundbar and TV’s ports. |
| 3 | If the cables are physically damaged, replace them. |
| 4 | Test the system again to see if the issue persists. |
Why This Works: While Bluetooth has evolved dramatically over the years, it’s still the type of connection most susceptible to signal interference. Wired connections eliminate this problem entirely.
Issue 3: Surround Speakers or Subwoofer Isn’t Working
TCL has largely streamlined its setup process with its complete surround sound system packages. Effectively, after the soundbar, rear speakers, and subwoofer have been plugged into power sources, they should automatically identify each other and pair together.
However, parts of the ensemble sometimes have issues making that seamless connection. If you can’t hear the bass in the music or movies you’re watching, or if there’s no sound at all coming from your rear speakers, it’s likely that they aren’t paired to your soundbar.
How to Fix It
| Step | Action |
|---|---|
| 1 | Unplug everything—the soundbar, subwoofer, and rear speakers. |
| 2 | Power up the soundbar first, since it effectively operates as the brains of the system. |
| 3 | Power up the subwoofer next. |
| 4 | Complete the process with the rear speakers. |
| 5 | If they still aren’t connecting, manually pair each piece per the soundbar’s included instructions. |
Manual Pairing
The process differs slightly from system to system, but it generally involves:
-
Holding a reset button on the subwoofer or speakers.
-
Plugging them into power while holding the button.
-
Waiting for the pairing indicator light to confirm connection.
Pro Tip: If you’re still experiencing issues with connections, audio, or anything else with your TCL soundbar, it might be worth reaching out to TCL’s customer support team for additional troubleshooting.
