Certain Televisions include a physical switch that switches the loudspeakers on and off; test if you can find and activate that button. Some Televisions offer this option in the sound settings; if it's turned off, enable it. Another television category has three choices: SAP, mono, and stereo in the audio menu options. Regular use does not activate the SAP option. Change the choice to either Stereo or Monochrome. If these measures do not address the problem, you must seek expert assistance.
