Working on a TV can be difficult and dangerous due to the high voltage circuits inside. Always remember to unplug any TV before trying to service it and if unsure of the proper procedures, seek the service of a trained professional.



I'm sorry to hear that your television has lost audio and I would like to assist you.  I advise checking the audio settings to verify that the speakers have not been turned off.  You will also want to attempt to use another source of audio, like a dvd player or the like.  If the issue is still there, it will likely require the television to be serviced by a technician who will be able to replace the circuit board that contains the audio circuit.


Please let me know if you would like any further assistance.
