Few things are more frustrating than turning on a Samsung TV only to discover there is a perfect picture—but absolutely no sound. Whether it happens after a software update, a recent settings change, or seemingly out of nowhere, audio issues are surprisingly common across Samsung’s LED, QLED, OLED, and Crystal UHD models. Fortunately, most sound problems are not hardware failures and can be resolved in just a few minutes.
TLDR: If a Samsung TV has no sound, the problem is usually caused by muted output, incorrect audio settings, external device conflicts, or outdated software. Checking the volume, running a sound test, restarting the TV, inspecting cables, updating firmware, and resetting audio settings fix the issue in about 85% of cases. These steps work for most Samsung models made in the last decade.
1. Check the Basics: Volume, Mute, and Output Settings
It may seem obvious, but a surprising number of “no sound” cases are caused by simple audio settings. Before diving into advanced troubleshooting, verify the essentials.
- Ensure the TV is not muted.
- Increase the volume using the remote.
- Make sure the correct Sound Output option is selected.
To check the sound output:
- Press the Home button on the remote.
- Go to Settings.
- Select Sound.
- Choose Sound Output.
If external speakers or a soundbar are connected, the TV may be routing sound elsewhere. Switching the output back to TV Speaker often restores audio instantly.
Users should also confirm that Bluetooth headphones, if previously connected, are not currently paired. The TV may silently redirect sound to them even when they are not nearby.
2. Run the Built-In Sound Test
Samsung TVs include a built-in diagnostic feature that plays a test tone or sample audio. This helps determine whether the issue originates from the TV hardware or an external device.
To run the sound test:
- Open Settings.
- Select Support.
- Choose Device Care or Self Diagnosis (depending on model).
- Select Start Sound Test.
If the test sound plays successfully, the TV’s internal speakers are working correctly. The issue likely lies with:
- An HDMI-connected device
- A cable box
- A streaming stick
- An audio receiver
If the test produces no sound at all, it may suggest a deeper system or hardware issue.
3. Power Cycle the TV (Properly)
Modern Samsung TVs operate much like small computers. Software glitches can temporarily disable sound, especially after firmware updates or abrupt shutdowns.
A full power cycle clears residual electrical charge and refreshes system software. Here’s how to do it:
- Turn off the TV.
- Unplug it from the wall outlet.
- Wait at least 60 seconds.
- Press and hold the power button on the TV (not the remote) for 10 seconds.
- Plug the TV back in and turn it on.
This simple reset resolves minor firmware conflicts in many cases.
It is important not to skip the waiting period. Simply turning the TV off and back on does not achieve the same effect.
4. Inspect HDMI and External Connections
Audio frequently disappears when external devices are involved. Faulty HDMI cables, loose connections, or mismatched input settings can disrupt sound transmission.
Users should:
- Disconnect and reconnect HDMI cables.
- Try a different HDMI port.
- Replace the HDMI cable entirely.
- Test the device on another TV if possible.
Sometimes the issue occurs because the external device’s volume is turned down or muted independently of the TV.
If using HDMI ARC (Audio Return Channel) with a soundbar or AV receiver:
- Ensure HDMI-CEC (Anynet+) is enabled.
- Confirm ARC is turned on in sound settings.
- Verify the cable supports ARC or eARC.
Improper ARC configuration is one of the most common causes of lost sound when using external audio systems.
5. Update the TV’s Software
Software bugs occasionally affect audio output. Samsung regularly releases firmware updates to address compatibility problems and performance issues.
To check for updates:
- Press Home.
- Go to Settings.
- Select Support.
- Choose Software Update.
- Select Update Now.
If the TV is connected to Wi-Fi, it will search for the latest version automatically.
After updating, restarting the TV ensures changes are fully applied. Many intermittent sound issues resolve immediately after installing pending firmware updates.
6. Reset Sound Settings or Perform a Factory Reset
If all else fails, resetting audio configurations can eliminate conflicting settings that may be suppressing sound.
To reset sound settings only:
- Open Settings.
- Select Sound.
- Choose Expert Settings.
- Select Reset Sound.
This restores audio settings to default without affecting apps or picture preferences.
If the issue persists, a full factory reset may be required:
- Open Settings.
- Select General.
- Choose Reset.
- Enter the PIN (usually 0000).
A factory reset erases all custom settings, installed apps, and network information. While more extreme, it resolves persistent software conflicts in many cases.
When It Might Be a Hardware Issue
Although rare, hardware failures can occur. Signs of a hardware problem include:
- No sound during the built-in sound test
- Distorted or crackling audio
- Sound that cuts in and out randomly
- Physical damage to speakers
In such cases, professional servicing may be necessary. Internal speaker replacement or motherboard repair is beyond basic troubleshooting.
Preventing Future Sound Problems
Once sound is restored, several precautions can help reduce future issues:
- Avoid unplugging HDMI devices while powered on.
- Keep firmware updated.
- Use high-quality HDMI cables certified for ARC or eARC.
- Power down devices properly instead of unplugging abruptly.
- Periodically restart the TV to refresh system memory.
Proper cable management and consistent software updates significantly reduce recurring problems.
Frequently Asked Questions (FAQ)
Why does the picture work but there is no sound?
This usually indicates an audio output setting issue or a problem with an external device. Running the TV’s built-in sound test helps identify the cause.
How do I get sound back on my Samsung TV quickly?
First, check if the TV is muted and confirm the correct sound output is selected. Then perform a full power cycle by unplugging the TV for 60 seconds.
Why did my Samsung TV lose sound after an update?
Occasionally, firmware updates reset or alter audio settings. Checking Sound Output and running a software update again can resolve compatibility issues.
Does factory reset fix sound problems?
In many cases, yes. A factory reset eliminates conflicting configurations and restores default settings, solving persistent software-related sound issues.
Can a bad HDMI cable cause no sound?
Absolutely. HDMI cables transmit both video and audio. A partially damaged cable may allow video to display while preventing audio from passing through.
What if the built-in sound test does not work?
If no audio plays during the sound test, the problem may be internal hardware failure. Contacting customer support or scheduling service would be the next step.
Why is there sound on apps but not on cable TV?
This often indicates an issue with the cable box or HDMI input rather than the TV itself. Testing different inputs can pinpoint the problem.
Audio issues on Samsung TVs are typically straightforward to fix. By methodically checking output settings, testing internal speakers, rebooting the system, inspecting cables, updating firmware, and resetting configurations, users can resolve the vast majority of no-sound problems in minutes—without professional repair. In most cases, the silence is only temporary and easily reversed with the right steps.
