Sharp TV No Sound? 10 Easy Fixes to Restore Audio

Few things are more annoying than turning on your Sharp TV, seeing a perfect picture, but hearing no sound at all. Whether you’re using a Sharp Smart TV, a Roku version, or a standard LED model, this “Sharp TV no sound” issue happens more often than you’d think and in most cases, it’s easy to fix. In this guide, we’ll go through all the common reasons why your Sharp TV might have no sound and walk you through the exact steps to get it working again. By the end, you should have your TV’s audio back without needing to call a technician.

Check the Basics: Volume and Mute Settings

Let’s start with the easiest thing to check your volume settings. It’s surprisingly common for TVs to be muted or the volume turned all the way down by accident.

Here’s what to do:

• Make sure the TV volume isn’t set to zero.

• Look for a mute icon on your screen. If you see one, press the Mute button on your remote to unmute.

• Try using the volume buttons directly on the TV instead of the remote.

• If the remote still doesn’t work, the batteries might be dead or the remote could be faulty. Replace the batteries and test again.

Test with Different Input Sources

If you’re using an external device like a set-top box, streaming stick, or Blu-ray player, the sound issue might not be from your TV at all it could be from that device.

Here’s how to check:

• Switch to another input, such as HDMI 2 or AV.

• Play something from a built-in app like YouTube or Netflix.

• If you get sound from a different source, the problem is likely with your external device or its cable.

And if one HDMI port has no sound but another works fine, that could mean the port is damaged or the connected device isn’t sending out audio correctly.

Perform a Power Cycle (Soft Reset)

Sometimes, a simple restart can fix temporary sound glitches caused by minor software hiccups. Here’s how to do it:

1. Turn off your TV.

2. Unplug the power cord from the wall.

3. Wait at least 60 seconds.

4. While it’s unplugged, press and hold the Power button on the TV (not the remote) for about 10 seconds. This helps drain any leftover power.

5. Plug it back in and turn it on.

This quick reset refreshes the TV’s internal circuits and often brings the sound back right away.

Check Audio Output Settings

Sharp TVs can send sound through different outputs like TV Speakers, HDMI ARC, or Optical Audio. If the wrong one is selected say your TV is set to use an external speaker you’re not actually using you won’t hear anything.

Here’s what to do:

1. Go to Menu > Settings > Sound > Audio Output.

2. If you’re using the built-in speakers, select TV Speakers.

3. If you’re using an external sound system, make sure HDMI ARC or Optical is selected correctly.

4. Exit the menu and test the sound.

A quick check here usually fixes the problem if the sound settings were just misconfigured.

Disconnect Any Bluetooth Devices

If your Sharp TV isn’t making any sound, Bluetooth could be the reason. Many Sharp TVs automatically connect to Bluetooth speakers, headphones, or soundbars. When that happens, the TV’s built-in speakers turn off.

Here’s how to fix it:

1. Open Settings and go to Bluetooth.

2. Disconnect any paired devices.

3. If you’re not using Bluetooth, just turn it off completely.

Now play something again. If you hear sound, the issue was a Bluetooth connection blocking the TV speakers.

Check the Audio Format

Another common cause is an unsupported audio format. Some movies or shows use formats like Dolby Digital or DTS, which your TV might not support. When that happens, you’ll get silence.

How to fix it:

1. Go to Settings > Sound > Audio Format.

2. Change the format to PCM (Pulse-Code Modulation).

PCM is the safest option since almost all TVs and devices can handle it. After switching to PCM, test your sound again it should be working now.

Update Your Sharp TV Firmware

Outdated firmware can sometimes mess with your TV’s sound. Thankfully, updating it is quick and easy:

1. Make sure your TV is connected to Wi-Fi.

2. Go to Settings > Support > Software Update.

3. Select Check for Updates.

4. If an update is available, install it.

5. When it’s done, restart your TV.

Firmware updates often fix bugs that cause audio issues, so this simple step can make a big difference.

Check HDMI or AV Cables

Loose or damaged cables are another common reason for losing sound. Take a look at your setup and check for:

• HDMI connections that aren’t fully plugged in.

• Cables that look bent, frayed, or worn out.

• Older HDMI cables that may not properly carry audio signals.

If anything looks off, swap the cable for a new high-speed HDMI 2.0 or newer version. You can also try a different HDMI port. If your sound comes back, the old cable or port was likely the culprit.

Test Other Apps or Channels

If the sound problem only happens in one app or channel, your TV is fine the issue is with that specific app or content.

Here’s what to try:

• Play something from another app like YouTube or Netflix.

• Switch to live TV or a different HDMI source.

If sound works everywhere else, uninstall and reinstall the problem app. Streaming apps can sometimes glitch after updates or when the cache gets full. A quick reinstall usually fixes it.

Reset Sound Settings to Default

If you’ve adjusted settings like the equalizer, balance, or other advanced sound options, something might’ve been changed accidentally. Resetting everything back to default often fixes small audio issues.

How to reset:

1. Go to Settings > Sound > Reset Sound Settings.

2. Confirm the reset when asked.

3. Restart your TV.

This will restore the original sound setup and usually clears up any wrong configurations.

Factory Reset the TV

If nothing else works, a factory reset might be your last option. This wipes all apps, settings, and saved data, returning your Sharp TV to its original state.

Here’s how:

1. Press the Menu button on your remote.

2. Go to Settings > System > Reset > Factory Reset.

3. Enter your PIN (the default is 0000).

4. Confirm the reset.

Once done, your TV will restart like it’s brand new. Set it up again and test the sound to see if it’s working.
