How Do I Make My Optical TV Work?
It’s quite common for cables and ports to get damaged and not work properly at times, but most of the time you aren’t aware so you try every fix there’s in the book.
If you’re facing the same issue with your Optical sound, I suggest you first check your settings if the Output is on Optical or not, if it is, then we can consider the broken or damaged cable and the port.
Here’s how you can check if the Output is Optical or not:
- Open Settings on your TV.
- Find Sound.
- Scroll until you find Sound Output.
- Now there you’ll see Optical, click on it.
If the Output isn’t on Optical, change it.
Also, make sure that both HDMI Input Audio Format and Digital Output Audio Format are on the PCM setting. You can check that by going to Settings > Sound > Expert Settings.
In addition, now that you have changed the Output to Optical, power off your TV, wait 1 minute, and turn it on, you should be able to hear the sound.
However, if you still don’t hear any sound, now you should consider the possibility of broken or damaged cable and port.
Can Unplugging Fix The Optical Sound In My Samsung TV?
If nothing worked so far, I believe it’s time to try unplugging. While it’s not guaranteed that it’ll work, miracles happen.
I don’t want you to unplug and immediately plug it back in, because that won’t make much difference, here’s what I want you to do:
First, you need to unplug your TV, wait 1 minute, and plug it back in. Now press and hold the Power button, which is on your Samsung TV for only 30 seconds, be sure to hold for the whole 30 seconds because that’s where the magic will happen.
Well, this should fix the issue, however, if it didn’t then you should consider a factory reset.
