JVC TV Sound Quality – Fix

JVC TV Sound Quality – Fix

JVC TV models are known for bringing on-screen pictures to life with better color quality, but you might experience low sound quality issues while viewing your favorite channel. 

In this article, we’ll explore why your TV is experiencing audio issues and in what ways you can have better sound with easy step-by-step instructions.  

Why is my JVC TV sound quality low? 

  • Incorrect equalizer or surround sound settings. 
  • Small built-in speakers on the TV. 
  • Loose or faulty HDMI or other sound cable. 
  • Hardware issues. 
  • Low volume on the TV
  • Outdated TV firmware.
  • Minor bugs causing the TV to glitch. 

How do I fix JVC TV sound quality? 

Power Cycle the TV

Before you go for any advance fix, try power cycling your JVC TV. This will clear out any system bugs that are causing the TV to glitch and result in the sound quality problem.

To do this:

  • Press the “Power” button on the front or back control panel of your JVC TV.
  • Disconnect your JVC TV from the power source by unplugging its cable from the wall outlet. 
  • Wait 30-40 seconds.
  • Plug back the power cable into the mains and press the “Power” button to turn on the TV.

Afterward, watch any channel or on-demand content and see if the problem is resolved. 

Check the HDMI or Sound Cable

A loose or defective HDMI or other sound cable connected to your JVC TV and external audio device might be the reason for your problem. 

Therefore, ensure the audio cable is securely connected to the back of your JVC TV and the audio device. Also, carefully inspect the cable for any damage and replace it with a new one. 

NOTE: It is possible that you’ve lowered the volume on your TV. This makes it seem that the sound quality is poor. So, increase the volume to a comfortable level and verify if this helps.

Use an External Sound Bar

Some JVC TVs have a small internal speaker, due to which the sound quality is affected. 

So consider investing in an external soundbar or speaker system to get more immersive and clearer sound while watching Live TV or streaming app content. 

You can connect the soundbar to your JVC TV through HDMI, Optical cable, Aux, or Bluetooth. 

Change the Equalizer Settings

JVC TVs have equalizer settings that allow you to adjust different frequency ranges. But if these settings are misconfigured, it can lead to various quality issues, such as sound distortion or tinny volume. 

Therefore, change the equalizer settings on your JVC TV by following the steps given below and fine-tune the audio to your liking: 

Now, make these changes based on your preferences:

For Movies:

  • 1.5kHz: 5dB
  • 5KHz: 12dB
  • 10KHz: 12
  • 120Hz: 10dB
  • 500Hz: -6dB


  • 1.5kHz: 5dB
  • 5KHz: 10dB
  • 10KHz: 12
  • 120Hz: 5dB
  • 500Hz: 0dB


  • 1.5kHz: 5dB
  • 5KHz: 10dB
  • 10KHz: 12
  • 120Hz: 0dB
  • 500Hz: 0dB

Once you do that, check the sound quality on your TV and verify the fix. 

Change Surround Sound

Some users report that changing the surround sound settings through the Service Menu on their JVC TV also helped them fix the issue. Here’s how:

  • Press “Menu” on your JVC TV remote. 
  • Press “4 7 2 5” one after another to enter the Service Menu.
  • Select “Audio Settings.”
  • Change the Surround Type to “Other.” 

Afterward, check the sound on your JVC TV, and the issue should be resolved now.

Check for Updates

If your JVC TV is running on an outdated firmware version, it may lead to audio quality problems. 

To prevent this, keep your TV up-to-date, along with the audio driver, with these instructions:

  • Press “Menu” (on the remote). 
  • Select “System.” 
  • Choose “Settings.” 
  • Choose “More.”
  • Select “Software Update.” 
  • Select “Scan for Update.”
  • Follow the on-screen instructions to update your JVC TV to the latest version. 

After updating your JVC TV, hopefully, the audio quality will be back to normal. 

Reset JVC TV

As a last resort, try performing a factory reset on your JVC TV. This will resolve temporary glitches and software issues that result in poor sound quality. To do this:

  • Press “Menu.” 
  • Select “Settings.” 
  • Choose “Storage & Reset.” 
  • Choose “Factory Data Reset.”
  • Confirm this action to reset the TV to default settings.

Afterward, reconfigure your JVC TV and check if this resolves the problem. 

NOTE: Keep in mind that resetting your JVC TV will erase all your settings and personalizations, and everything will be back to default. 

Diagnose and Fix Hardware Issues

If you’ve tried all the above fixes, the built-in speaker on your JVC TV might be faulty or damaged.

So, seek professional help from a qualified technician to repair or replace the speaker in your TV. 

You can also reach out to the JVC Support team to discuss this problem with them. They will provide you with a more specified solution.
