A TV with no sound but picture is like a phone with no network – you can see everything, but the communication is incomplete.

Fortunately, this common issue can often be resolved with a few simple troubleshooting steps. In this article, we’ll discuss how to fix a TV with no sound but picture issue.

TV with no sound but picture: 12 fixes

In this section, we will present 12 fixes by which you can resolve your TV with no sound but picture issue easily.

Check volume and mute settings

Maybe the TV’s volume and mute buttons have been adjusted by someone without your knowledge. So, it is better to check these settings first before moving on to the technical fixes.

Volume controls

Ensure that the TV’s volume is turned up to an audible level. Locate the volume buttons on your TV remote or the TV itself and adjust accordingly.

Mute settings

Check if the TV is muted. Press the Mute button on the remote control or navigate to the TV’s settings menu to disable the mute function.

Examine audio output settings

We will advise you to examine audio output settings both for external devices and for internal speakers.

External devices

If you have connected external devices such as a soundbar or home theatre system, ensure that they are powered on and properly connected to the TV. Verify the audio output settings to ensure they match the connected devices.

Internal speakers

If you own a TV with built-in speakers, confirm that the audio output is set to internal or TV speaker in the TV studio settings. Adjust the balance and equalizer settings to ensure they are not affecting the audio output.

Check cable connections

Are gold HDMI cables and 3.5mm audio connectors better?

Here, we’ll talk about the HDMI or audio cables and the optical or RCA cables.

HDMI or audio cables

If you are using external devices, check the HDMI or audio cables connecting them to the TV. Ensure they are securely plugged into the correct ports and not damaged or loose. If the cables are damaged, replace them asap.

Optical or RCA cables

For TVs with optical or RCA audio output, inspect the cables and connections. Replace any damaged cables and ensure they are tightly connected.

Test with different audio sources

Connect alternative audio sources such as a DVD player or gaming console to the TV to determine if the issue lies with a specific source or the TV itself.

If the sound works with other sources, it indicates a problem with the original source device.

Try different audio outputs

If your TV has multiple audio output options, such as HDMI ARC, optical, or headphone jack, try connecting your audio device to a different output port. This can help determine if the issue is specific to a particular audio output.

If this didn’t fix the TV with no sound but picture issue, follow the other instructions given below.

Disable audio output formats

Some TVs support various audio output formats, such as Dolby Digital or DTS. In the TV’s audio settings, try disabling specific output formats and test the sound. Incompatible formats may result in no audio or distorted sound.

Check surround sound settings

If your TV supports surround sound, adjust the audio settings to match your speaker configuration. Incorrect settings may result in audio being routed to speakers that are not connected or activated.

Reset audio settings to default

In the TV’s audio settings, look for an option to reset the audio settings to their default values. This can help eliminate any custom settings that might be causing the audio problem.

Power cycle the TV to fix no sound but picture

Power cycling a TV refers to the process of completely turning off the device, disconnecting it from the power source, and then reconnecting and turning it back on. It helps to reset the TV’s internal components and can resolve certain issues or glitches.

Here’s how to perform a power cycle of the TV:

  • Locate the power button on your TV or the remote control.
  • Press and hold the power button for about 10-15 seconds until the TV turns off completely.
  • Once the TV is powered off, unplug the power cord from the electrical outlet or the back of the TV.
  • Wait for approximately 1-2 minutes to allow any residual power to dissipate.
  • Plug the power cord back into the electrical outlet or the TV.
  • Press the power button again to turn the TV back on.

Update firmware and drivers

Ensure that your TV’s firmware and any connected audio devices’ drivers are up to date. Visit the manufacturer’s website or use the TV’s settings menu to check for available updates and install them if needed.

Perform a factory reset the TV to fix no sound but picture

If all else fails, you can try performing a factory reset on your TV. However, note that this will erase all settings and personal data, so it should be a last resort.

Refer to your TV’s user manual or manufacturer’s website for specific instructions on how to perform a factory reset.

Consult professional support

If none of the above solutions resolves the issue, it’s advisable to seek professional assistance. Contact the TV manufacturer’s customer support or consult a qualified technician who can diagnose and repair any hardware or internal component issues.

That’s it. By following the above 12 steps, you can definitely fix a TV with no sound but picture issue.
