Test the TV with different inputs, as many as possible, whatever you have: antenna, cable or satellite box, DVD player, game box. Sound only missing with one input? You've partially solved it--check for a bad jack, cable, or source.
Sound missing on everything? If you have a headphone jack, insert the headphone plug in and out vigorously several times. A contact may be stuck in the open position on the back of the jack.
If picture plays, but no sound comes from the Mintek Combo device, first increase the volume to ensure that no sound plays at any volume level. If watching a station on television, change the channel to make sure the issue is not related to the television station. If you still experience problems, check the rear for loose audio input cables. Additionally, check the sound options in the "Menu" to ensure that the "Second Audio Program" or "SAP" sound option has not been activated.
