Why sound is Not Working on TV?

Your TV’s volume control issue can stem from various factors. Here are some of the most common reasons:

Why Won’t My TV Turn On

  1. Speaker Problems: If the built-in TV speakers are malfunctioning, the volume control might not work as expected. Troubleshooting the speakers could help resolve the volume issue.
  2. Media Device Connections: Devices like receivers, DVD players, or game consoles may not be properly connected to the TV due to disconnections, blocked ports, or incorrect settings.
  3. Cable Issues: If TV wires are exposed or if a plug cord from an external speaker device is accidentally disconnected, it can result in no sound output from the TV.
  4. Analog Broadcast Tuning: If your TV supports analog broadcast, performing analog broadcast tuning can help identify if noise is present. If there’s any unusual noise from the TV, check other potential sources like playback content or connected devices for sound.
  5. Driver or Software Issues: Inadequate drivers or software can impact specific channels or all channels, leading to sound problems. Ensure that your TV’s systems are up to date and functioning properly.

By considering these factors and conducting appropriate troubleshooting, you can address the issue of your TV’s sound not working.

How can the sound on a TV be fixed?

Smart TVs, while sharing many features, can have varying audio settings and configuration methods due to different brands. However, the following advice should aid you in restoring sound to your device.

Here are proven solutions to assist with troubleshooting:

  1. Restart the TV: Performing a power cycle is a foundational step in resolving common issues with your Smart TV. If your TV’s volume isn’t functioning or is stuck, power it off and then back on.

    If you encounter volume problems, consider unplugging the TV from the power source for approximately 10-15 minutes before plugging it back in. After rebooting, check if the volume issue is resolved. Follow these steps to restart your TV:

    • Hold the TV’s Power button for a few seconds.
    • Disconnect any associated devices.
    • Unplug the TV from the wall.
    • Plug it back in and restart the power.

    This seemingly simple process often proves effective as it updates your TV’s settings, potentially resolving the issue upon reboot.

  2. Verify Audio Settings: Review your TV’s audio input settings. Audio input refers to how audio signals are delivered to a device, such as your TV. Audio issues can arise when these settings are incorrect.

    Incorrect button presses on the TV remote are a common way audio settings can be compromised. For example, pressing “AUX” by mistake switches the audio input to AUX, requiring something to be connected to the AUX port for sound.

    On Samsung TVs, you can run a sound test to check audio settings:

    • Go to “Support” under Settings.
    • Select “Start Sound Test” and then tap “Self Diagnosis.”

    If audio settings are problematic, the test will indicate it. If an issue is found, you can reset your sound settings by navigating to Settings, choosing “Sound,” selecting “Expert Settings,” and finally, “Reset Sound.”

  3. Check HDMI Cable Connection (For TVs Using HDMI): HDMI cables can contribute to sound issues. These cables transmit both audio and video from external devices. Check if your HDMI cable connecting the set-top box to your TV is damaged or loosely connected. Securely insert both ends of the cable. Loose connections can sometimes lead to sound problems.

    Disconnect and inspect the HDMI cable for damage, then reconnect it. Verify if the issue is resolved and if the connections appear intact.

  4. Switch to Another Channel: If the problem isn’t related to speakers, TV, or audio settings, consider changing the channel. This can help determine if the issue is specific to the channel you’re watching.
  5. Check Mainboard Components: Malfunctioning mainboard components can impact a TV’s sound production. The mainboard, or motherboard, acts as the backbone of the TV. While identifying mainboard issues might be challenging, consider seeking professional assistance if needed.
  6. Contact TV Customer Service: If the problem persists or you need further assistance, reach out to your TV’s manufacturer. Check your warranty card for details on potential coverage. Customer service can guide you through troubleshooting or provide necessary support.


Remember to consult your TV brand’s website for customer service information, including email or phone support. If you have a warranty, you’re covered.

To address low volume on your TV:

4. Why is the music louder than the talking on my TV?

The disparity between music and dialogue volume on your TV can be due to speaker quality:

  • Many home sound systems emphasize high frequencies present in music, causing music to sound louder.
  • Human voices generally occupy lower frequency ranges that might not be as well-reproduced by standard speakers.
