Sound and picture out of sync on Samsung TV, well, search no further and keep reading.
Out-of-sync issues can vary from output devices to issues related to the source or input, but we will get it all cleared for you by the end of this guide!
Sync issues on your Samsung TV might be caused by a problem with the output devices and the essential source of the audio. The HDMI cable might also cause sync issues, as well as trouble with the input.
There are even more causes that you should be paying attention to so let’s review them all in-depth before proceeding with the solutions.
Samsung TV out of sync could be caused by several factors. From interruptions with the output speaker device to delayed HDMI data transfer on the audio side.
It is not excluded that the source/broadcast you’re currently watching is responsible for this delay as well.
Below we’ve listed all possible causes for this issue for you to inspect:
1. Devices Not Synced
It is possible that your home theater (audio configuration) is not synced with your TV.
2. Outdated Firmware
Even outdated firmware of your Samsung TV is capable of causing sync issues with the audio line.
3. Third-Party Devices/HDMI
Any third-party devices connected via the HDMI you’re viewing, could also lead to sound delay. Too long HDMI cables are well-known for delaying data transfer.
4. Current Broadcast/Source
A potential problem with the current broadcast or show you’re viewing could also cause a similar issue.
5. Sound Configuration Problem
Lastly, if you’ve changed the sound options in any way, you might have caused a slight fall-behind of the audio transfer.
These are the main suspects and now it’s time to address each of them so let’s jump right in.
Before you try applying any of the upcoming solutions, we suggest restarting your TV and re-plugging the output devices.
By doing so, you will refresh the sync in the video and hopefully fix the issue without bothering too much.
If a restart didn’t help, then proceed with the solutions in the order that they are listed:
First of all, switch the broadcast. By changing the show or media you’re viewing you will be able to tell whether the issue is occurring with your TV or the source you were watching.
If you have an antenna attached to your TV, feel free to browse throughout the rest of the channels.
If you’re using cable TV, you would also have plenty of alternatives to test out the sync on your Samsung TV.
If the problem appears on a certain group of channels or only within a specific application then the problem is not with your TV.
But if the out-of-sync issue is on ALL channels/media that you’re watching then the issue is more serious.
We recommend discharging your TV to resolve any temporal glitches that might have developed.
By discharging (power cycle), you will reboot ALL services including the audio line and hopefully fix the out-of-sync problem.
To discharge your TV, follow the steps down below:
- Turn OFF your TV using the Samsung remote.
- Unplug the power adapter and wait for ~5 minutes.
- Once discharged, re-attach the power adapter to your TV.
- Turn on your Samsung TV and test.
If you’re worried your TV might have power fluctuations, you might as well plug it to a different outlet during the process.
Tip: Avoid using power dividers and plug your TV in a power source that has been proven to work well.
This solution is meant for people with an entire Home Theater setup. That might include a soundbar with several speakers.
In such cases it’s possible that your configuration isn’t synced, thus, the audio or video may fall behind at some point while watching your TV.
Follow the given instructions to sync your home theater and resolve potential audio issues:
- Press the “Home” button on your Samsung remote and navigate to the settings.
- Tap on the “Audio” option and select “Expert”.
- Next, choose “Audio Delay”.
- Use the numbers to increase/decrease the audio delay.
The numbers on your screen respond to seconds.
You must measure how many seconds your audio is falling behind and increase the numbers given on your screen accordingly.
If the solution above didn’t help we suggest unplugging ALL audio output devices and using the default audio configuration of your TV.
This way, you will determine if the issue is occurring due to a fault with the given output devices, or you have to focus on troubleshooting the TV.
Unplug the AUX from behind your TV where your output devices connect. Go to Menu > Settings > Audio and choose “Default Audio” in the drop-down menu.
Once you’re done, restart your TV and check if the sync has been restored.
For Samsung TV users who use a third-party device to watch, we suggest inspecting & reconnecting the HDMI cable that transfers the audio and video from the third-party device.
If you’re using a cable box or a gaming console to watch various sources, make sure the HDMI is tightly plugged into the corresponding port and inspect the source.
Then double check if the source you’re using is the correct one as well as if the HDMI cable is shorter than a meter.
Longer HDMIs tend to transfer data more slowly thus delivering different types of audio/video delay.
In addition to troubleshooting the HDMI, you can try an HDMI handshake, where you practically grab the HDMI and shake it around. It might sound weird, but for some people, it does help so why not to try.
If your sound and picture are out of sync on Samsung there is a high possibility that the firmware version is outdated.
This is why we suggest updating the firmware to resolve any sync issues.
To update your TV, follow these steps:
- Go to the Settings of your Samsung TV.
- Select “Software Update” and choose “Update Now”.
- The update will start downloading and you will be able to apply it once it is done.
The TV may restart during the process, so make sure to wait it out patiently.
Once ready, test the audio/video sync, and if it’s not solved then proceed with the next step.
If nothing worked so far, we suggest resetting the audio configuration on your Samsung TV.
That will revert ALL audio settings to their default state and ensure that there is no misconfiguration in the settings.
To reset the audio of your Samsung TV follows these steps:
- Open the Menu on your Samsung TV.
- Head to the settings tab and select “Sound”.
- Scroll all the way down until you find the “Audio Reset” button and click it.
Wait for the TV to finish resetting the audio configuration and test your TV. You might as well reconnect your output devices to test while they are plugged in.
The very last option you’ve got is to factory reset the entire TV.
That will re-install the software and hopefully fix any potential glitches that might be causing out-of-sync problems.
Alert: The factory reset will erase ALL settings, configurations, and applications from your TV.
To factory reset your Samsung TV follow the steps below:
- Open the Settings.
- Go to General and select Reset.
- Enter the PIN (default is “0000”).
- Click on OK.
- Wait for the TV to reset.
Once the reset is over you can test the sync issue by viewing various sources and determine whether it’s fixed or not.
If not, well you can either bring your TV for inspection and possibly repair or contact Samsung customer support for additional troubleshooting.
