Onn TV sound issues (Volume low/not Working)

If you’re having sound issues on your Onn Roku TV, if the audio doesn’t seem to match up with the image on your screen, or even if your Onn Roku TV’s sound isn’t working completely or its volume is too low, you’re not alone. While many assume that the lack of sound is due to faulty wiring or an issue with their speakers, it could also be very basic.

Before you call an expensive service to fix the problem, try these quick fixes to see if they work. They might save you time and money in the long run.

Why is My Onn TV has no sound?

Why does my onn tv has no sound_

Your Onn Roku TV has no sound because your television’s audio input may be set to AUX, while your speaker system is set to ON/OFF/DIGITAL AUDIO OUT. Alternatively, maybe you have your speaker system connected to an audio output that isn’t receiving a signal from your television (such as from a cable box).

So the possible reasons for sound issues on your Onn TV might be:

  1. The Volume could be turned down.
  2. The mute button could be on.
  3. The TV could be connected to an external muted device or has its Volume turned down low.
  4. There could be something blocking the TV speakers.
  5. Your TV may be facing an internal software-related error.
  6. The TV speaker is malfunctioning.

Whatever the reasons, I will explain them in detail so that you can understand every step and do what is needed.

Fixing the Onn TV sound Issues

In short: To troubleshoot sound issues in your Onn TV, ensure that the Volume is turned up. If it is, try adjusting the settings. For this, go into the menu and look for the audio settings. Check your audio connections, such as HDMI or optical output, and the audio equipment connected to your TV and ensure that they are set to the correct input. If nothing works, factory reset your TV.

I’ll go over all possible solutions in further depth below, including what you’ll need to do to fix your TV. But before that, look at the below table for a better understanding…

Reasons Solutions
Volume is turned down Increase sound level
loose HDMI Tighten the cables
Internal software issues Reboot/Factory reset your TV
Malfunctioning Speaker Replace the Speaker

Step 1: Check the Cables

Before moving on to a more complex solution, check that all of your cables are correctly connected. If it’s an HDMI cable, make sure it’s plugged into both devices. Remember that HDMI 1.0 inputs can only support 1080p and lower resolutions, not all high-definition formats.

If you want to watch something at 2560×1440 or 4K resolution on your new flat screen HDTV from another source, such as your computer or game console, you may need to use a different cable.

Check your HDMI cable connections by connecting them to another device, such as a laptop computer or game console. If you can hear audio from those devices but not from your Onn TV, you most likely have a problem with one of your HDMI cables. Furthermore, you may have trouble receiving the TV signal if there is a problem with the HDMI cable.

Step 2: Make sure the audio player is plugged in properly

The second step is to ensure that your external audio device is plugged in and turned on, as well as your DVD player or VCR/DVR. These may appear simple, but they are to blame for many problems with TVs that do not have sound.

If your Onn TV’s sound is still not working, move on to the next step.

Step 3: Check Sound Levels

People tend to overlook the obvious. But that could be the root of the problem. Maybe your TV’s sound level is set to zero, and you don’t hear any sound from it.

So make sure the sound levels are where you want them to be. For this,

  • Look for the remote control’s sound level buttons on the right side.
  • Hit the mute or unmute button to see if it is muted.

If the sound is too low, too high, or distorted, use the Volume Up/Volume Down buttons to adjust the Volume.

Step 4: Check the Sound Settings and Connections

If step 2 and 3 fail to troubleshoot your issue, the next step you should do is to check the audio settings in your Onn TV. You can try different audio/sound settings and connections depending on the kind of speakers you’re using.

☞ Built-in TV Speakers

If you use the built-in TV speaker, check that they’re turned on. To do this,

  • First, press the “Home” button on the Remote.
  • Go to “Settings
  • Then go to “Audio.

Afterward, go to “Speakers” and ensure that the TV speaker option is marked. This indicates that they are switched on.

Also, ensure that the headphone output on the back of the TV is unplugged. The TV speakers will be muted if you connect anything to them.

☞ External Speaker

But if you are using an external output audio device, you’ll need to try a variety of things depending on the sound problem you’re having:

If no sound is coming from the external speakers, ensure they are turned on and properly connected. Look for any visible damage to the cable and connectors. If the cord is damaged, it may need to be replaced.

On the other hand, If the sound you’re hearing is too low or too loud, check that the external audio equipment’s sound levels are set correctly. And If the sound you’re hearing is distorted, recheck all of the above.

However, if you use the HDMI (ARC) connection, you must configure the CEC settings.

For this, return to the Settings menu by pressing the Back button on the Remote. Then go to “System” and double-check that ARC (HDMI) and System audio control are both checked under “control other devices (CEC).” These will allow your TV to output sound to external audio devices as well as control external sound systems via the TV remote.

Step 5: Identify and Fix TV Source Issues

It’s likely that the TV source 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.

Step 6: Turn off your TV  Completely

If none of these scenarios apply to you and you still can’t hear anything on your Onn television, you should turn off all power sources for 30 seconds and re-establish them in their original configuration.

This may resolve any interference, system, or temporary hardware issues causing sound issues on your Onn TV.

Step 7: Factory reset your TV

Still, not working? Well, in that case try resetting your TV to it’s factory settings. It’s a process of restoring a device to its original factory settings. This can be useful if the device is not functioning properly, or if you wants to restore the device to its original state.

However, it’s possible that your TV’s sound isn’t working properly because of incorrect audio settings made by you or other family members, and you can easily restore this setting to default by performing a reset. To reset your Onn TV, tap/click here.
