How to Troubleshoot a TV with No Sound but a Working Picture?

Is your television showing a perfect picture but there's no sound at all? Don’t worry—you’re not alone. Many users face this common issue, and the good news is that you can often fix it yourself without needing an immediate technician. In this guide by Duty Guy, we’ll walk you through simple yet effective steps to troubleshoot a TV with no sound but a working picture, especially for users in India looking for LED TV repair near me.

Step 1: Check the Basics First

Before diving deep, make sure the basic settings are correctly configured:

• Volume Level: Make sure the volume isn't muted or too low.
• Mute Button: Sometimes, the mute button may be accidentally turned on.
• Remote Control: Try increasing the volume using the TV’s panel buttons to rule out remote issues.

Sometimes these minor checks can resolve the issue without any technical help.

Step 2: Inspect the Audio Output Settings

Many modern LED TVs come with external audio support via Bluetooth or HDMI ARC. Here’s how to inspect:

• Go to TV Settings > Sound Settings > Audio Output.
• Ensure the output is set to “TV Speaker” if you’re not using external speakers.
• If you are using a home theatre or soundbar, check its power and input mode.

Incorrect output settings can easily cause the sound to stop working while the picture remains fine.

Step 3: Check Connected Devices

If you are using DTH set-top boxes, Fire TV Stick, or HDMI devices, follow these steps:

• Disconnect the device and reconnect it.
• Check the volume settings on the external device.
• Try using a different HDMI port.

Sometimes the problem lies with the device connected to your TV, not the TV itself.

Step 4: Try a Different Source

To rule out the current channel or input as the issue:

• Switch to a different channel or app.
• Try playing content from a USB drive or built-in app.

If the sound works on a different input or app, then the problem may be specific to the previous source.

Step 5: Restart or Power Cycle the TV

This step works more often than you'd expect:

• Turn off the TV and unplug it from the wall socket.
• Wait for 1–2 minutes.
• Plug it back in and power it on.

This resets the internal system and often resolves software glitches.

Step 6: Update the TV’s Software

Outdated firmware can sometimes cause sound issues:

• Go to Settings > About > Software Update.
• Make sure your TV is connected to the internet.
• Download and install any available updates.

Updating the software ensures that bugs are fixed and the system is stable.

Step 7: Perform a Factory Reset

If none of the above works, a factory reset might help:

• Navigate to Settings > System > Reset > Factory Reset.
• Follow the on-screen instructions.

Note: This will erase all your custom settings, so only do this if absolutely necessary.

When to Call a Professional

If you’ve tried all the above steps and still have no sound, it might be a hardware issue such as:
