How to Fix Samsung TV Distorted Sound

If your Samsung TV is producing distorted sound, this guide provides several methods to troubleshoot and resolve the issue. Follow the step-by-step instructions under each method to restore clear audio to your display.

Method 1. Check Basic Audio Settings

Ensure your TV’s volume, mute, and internal audio settings are configured correctly to avoid distortion.

Increase the Volume: Use the remote to raise the volume and verify that it’s not set too low.
Disable Mute: Confirm that the mute function is off by checking for any mute indicators on the screen.
Access Sound Settings: Navigate to the TV’s settings menu and select the audio or sound section.
Review Speaker Options: Ensure the correct speaker configuration is selected (e.g., TV speakers if no external device is used).
Test with Content: Play a program to see if the audio distortion persists after confirming these basic settings.

Method 2. Inspect External Audio Connections and Devices

Loose or damaged cables and improperly connected external devices can contribute to distorted sound.

Examine All Cables: Check HDMI, optical, RCA, or any audio cables connecting external devices to the TV for any signs of wear or damage.
Ensure Secure Connections: Make sure all cables are firmly connected to both the TV and the external audio devices.
Test Alternative Cables/Ports: Replace cables or try different input ports to rule out connection issues.
Verify External Device Settings: If using a soundbar or home theater system, confirm that it is set to the correct input and operating normally.
Check for Interference: Ensure that no other devices nearby are causing interference with the audio signal.

Method 3. Adjust Audio Output Settings

Misconfigured audio output settings may result in distorted sound, so verifying these settings is essential.

Open the Audio Menu: Using your remote, access the audio or sound settings in the TV’s menu.
Select the Correct Output: Choose between TV speakers, external speakers, or another connected audio device as appropriate.
Modify Audio Format: Change the audio format (e.g., PCM, Dolby Digital) to a format that is compatible with your setup.
Save and Test: Confirm the changes, then test the TV with various content to determine if the distortion is resolved.

Method 4. Change Sound Mode and Equalizer Settings

Incorrect sound modes or custom equalizer settings might be causing the audio to sound distorted.

Access Sound Modes: Navigate to the sound mode options in the audio settings.
Select a Different Mode: Switch between different sound modes (such as Standard, Movie, or Clear Voice) to see if the distortion improves.
Review Equalizer Settings: If available, adjust or reset the equalizer settings to default.
Test with Multiple Programs: Play different types of content to ensure that the new settings work consistently across all audio scenarios.

Method 5. Update the TV’s Firmware

Outdated firmware can sometimes cause audio issues, and updating it may resolve distorted sound problems.

Navigate to Support or Software Update: Open the TV’s settings menu and go to the ‘Support’ or ‘Software Update’ section.
Check for Updates: Select the option to search for firmware updates.
Download and Install: Follow the on-screen instructions to download and install any available updates.
Restart and Test: After updating, restart your TV and test the sound to determine if the distortion has been corrected.

Method 6. Perform a Power Cycle

A power cycle can reset the TV’s internal components and may eliminate temporary glitches causing audio distortion.

Turn Off the TV: Use the remote or the TV’s power button to shut it down.
Unplug the TV: Disconnect the power cord from the outlet and wait for at least 60 seconds.
Discharge Residual Power: Optionally, press and hold the power button for about 10–15 seconds while unplugged.
Reconnect and Restart: Plug the TV back in, power it on, and check if the sound quality has improved.

Method 7. Reset the TV to Factory Settings

A factory reset restores the TV to its default settings, potentially resolving any persistent audio distortion issues.

Access the General Settings: Open the TV’s settings menu and navigate to the ‘General’ or ‘Support’ section.
Locate the Reset Option: Find the option labeled “Reset” or “Factory Reset.”
Enter the Security Code: If prompted, input the default code (commonly “0000”) or your personalized code.
Confirm and Wait: Follow the on-screen instructions to complete the reset process and allow the TV to reboot.
Test the Audio: Once the reset is complete, play content to check if the distorted sound issue has been resolved.

Method 8. Contact Samsung Support or a Professional Technician

If none of the troubleshooting methods resolve the issue, professional assistance may be necessary to diagnose deeper problems.

Gather Information: Record your TV’s model number, serial number, and detailed description of the distorted sound issue.
Review Warranty Status: Check your warranty to see if the repair or replacement of the TV qualifies under the terms.
