If you connect headphones to your TV and you can’t get sound, then you might want to unplug the headphones. Check if the sound appears. If so, then the TV is working fine. If not, then you can move to the next recommendation

5. Disconnect and reconnect the cable leading to the external device

If your TV fails to produce sound after connecting an external device, you should disconnect and reconnect the cable leading to the external device to see if it solves the problem. Loose connections can cause dropouts so you should confirm that the cable is well connected at both ends. You should try to use a new cable if the problem persists.

You might also want to try a different port on the port.

6. Test the HDMI cable

Sometimes the problem could be due to a bad HDMI cable. You can check if the HDMI cable is bad by performing a HDMI test. Unfortunately, not all TVs have this feature. If you’re using an older model, you’re less likely to find it. Keep in mind that the test is designed for HDMI cords less than 2 meters and may not give accurate results on longer cords. Also, it won’t work on a soundbar or home theater system and is only designed for devices which include a video signal.

To perform the test, make sure the TV’s source is still on the HDMI setting for the cable you want to test. After that, navigate to Settings > Support > Self Diagnosis > Signal Information > HMDI Cable Test > Start Test.

If the test says the cable is bad, then you will have to replace the cable.
