You’ve worked so hard the whole day and finally got some spare time, now all you want to do is to sit back and watch some TV. Maybe finally you can catch up with your favorite drama series or just watch a movie. You selected the show and leaned back on your cozy sofa. Then suddenly the TV sound just cuts out and reverts back to normal. You must be thinking, “Nah, it just a one-time thing”, then the audio cuts out again. The TV sound keeps cutting in and out, then a sudden dreadful realization that your TV night is officially over.
Surprisingly, this is a rather common issue not just for old smart TVs but it could also happen to a brand new 4K smart television. It can be a frustrating experience especially if you need to unwind and just chill after a hard day’s work. It could also be an expensive headache as you need to send it for repair but your warranty has expired. There’s no need to be frantic, this issue may be solvable with a quick fix that can be done by you. Let’s go through some troubleshooting first and try to isolate the problem, then maybe we could apply a fix to it.
Let’s Troubleshoot and Isolate the Problem
Before you decide to carry the whole smart television and send it for repair, you should at least give troubleshooting a try. Not only you can isolate the problem, you might even solve the issue without the need to pay for repairs. Like there’s a saying goes, knowing is half the battle, so let’s move on.
Is your TV speakers turned on
There are TV models which require you to set the TV speakers ‘On’. You should be able to access the option via the menu button on your remote controller.
Upgrade TV Firmware
Is your television firmware up to date? If not, you should update the firmware asap as it may solve the issue. You can contact manufacturer support so that they can guide you with this process. Do not use firmware updates from unknown source as it maybe corrupted.
Change HDMI Cable
Sometimes changing the HDMI cable may just do the trick. You can try testing this theory with a spare working HDMI cable. If the problem stops, that means your previous HDMI cable could be damaged. But before you throw it away to get a new one, you can try cleaning both ends of the ‘faulty’ HDMI cable if is dirty. Then try it once more to see if it works fine.
Change HDMI Port
If you have a spare HDMI port on your television which you can use, please do so. If the problem stops, that will mean your previous HDMI port is faulty.
Check for loose connections
Check for any loose connections, try to refasten all your cable connection too. Test your television again. Loose wirings is dangerous, and it may also cause audio to cut in and out.
Self Diagnosis Tools
There are TV brands and models which integrates a self diagnosis tool into the system. You should be able to access them via the menu. For some TV brands/models, you are able to do a sound reset as well. Once done, proceed to check if the TV audio still cuts out.
Set to PCM
You can try changing from Dolby Digital to PCM via your television audio settings. You should also change any sound modes and/or EQ settings back to normal. Check if the problem still persists.
Turn off and on again
You must have heard this phrase before. Try turning your TV off, wait for about 10-15 seconds then turn it back on again. Hopefully this simple task will fix your intermittent audio loss issue.
Source Components – Cable Box, Blu-ray Player and others
It could be your cable/satellite box or your Blu-ray player that is causing your TV speaker’s sound to be cut out intermittently. For instance, let’s say the problem started when you were using your cable box, you should try using other source components such as your Blu-ray/DVD/CD player, gaming consoles, laptops/mobile devices, etc. If there is no issue with other source components, this will mean the problems lies with your cable box.
For further confirmation if it is the source component that is causing the problem, you should also change the connecting cables to new ones and change to another TV input(s). Do another test to see if the problem persists.
Internet is lagging
If you are using streaming services such as Netflix, Disney+, etc. A sluggish internet may affect audio quality like audio delay and maybe audio been cut out. It could also be the server issue of the platform you are using. You can check online for any current surge of complaints about the streaming service you are using. If there are complaints, probably you’ll need to wait it out or contact their support. For your internet, if is lagging badly, you might want to check with your internet service provider.
The internet issue may also caused by your router as it can affect your connecting devices such as mobile phones, tablets, laptops, etc. For example, you are using your mobile phone to play YouTube videos on your television but due to faulty router, your phone’s internet connectivity is bad thus creating both video and audio problems..
Turn off Anynet
For Samsung TVs, you may want to try turning off the Anynet function via your television settings. Anynet functionality is to allow you to control all your peripherals by using just one remote control.
Try using Headphones
You can connect your headphones to the TV and see if it encounters the same audio cutting in and out issue. When it doesn’t, this will mean your speakers are likely the ones that are faulty.
Connect External Speakers
You either use your own speakers or your friend’s to do this test. We shall use soundbar as an example, connect it to your TV and start playback. If the soundbar has audio cutting in and out, then this means your TV speakers are not at fault. If the problem stops, that means your TV speakers are most likely kaput. It will be a great opportunity to get better speakers.
Energy Saving Mode
There are a few television models that come with energy saving mode (for audio), which will cut off the speaker’s sound if there are no audio signal. Once the TV receive an audio signal, it revert the speakers back to normal. This could be why your TV is having intermittent audio loss. You should be able to turn off this mode via your TV settings. Or you can also just turn up the volume higher.
Reset your TV
I usually find this as the last resort but resetting your TV might work.
As you can see, there are quite a number of causes as well as potential fixes. You might even manage to find the problem and fix it midway. I will suggest you go through the rest of the troubleshooting methods, just in case if there are more issues. Sometimes though, you will have no choice but to send your tv for repair, and hopefully, it is still under warranty.
In the future, when you are planning to buy a new television. You might want to check customer reviews before buying. Some TV models may have a lot of issues and require the manufacturer to develop a software update to fix them. The development could take many months. Sadly, I have seen some reviews whereby the customers are waiting for a software update from the manufacturer for almost a year, so to fix their televisions’ problematic issues.
