Voice on my tv

@paulsospeter if you hve no audio the issue could be related to the audio amp on the main board or with the speakers. You also want to check how your TV is connected. If you are using HDMI try a different cable and/or a different input source like Coax or Composite.

If changing the connection does not yield any results, remove the back cover from your TV ( disconnect the power plug) and have a look at the main board. Check for any charred, missing or otherwise damage looking components. You can always post pictures of what you see with your question. That way we can see what you see. Adding images to an existing question

You can also try to connect a separate speaker to your TV right from the connector on the main board. If that works you will know it is your speaker that has failed.

Of course, also make sure that your TV's settings are properly set to whatever Audio you are using.
