Why is not sound coming from my television?

@lokendraku80696 check all of your audio settings. Make sure that you have selected proper input and output. If you are using HDMI cables, change those since they can be the culprit. If after all of that, it still does not have any sound then the issue could very well be with the audio circuit on the main board. If your TV has an audio jack, try that with some headphones etc. After that, it's time to open up the TV and to investigate the main board.

We will need to know the exact make and model for you TV to try and help you further.
