Question about Symphonic Televison & Video
If you are using a cable/satellite receiver or digital converter, I would suggest resetting the receiver/converter. Some can be reset by simply switching off and on, some have a reset button and others need to be disconnected from the power supply for a minute or so. Reset the box, then try the TV again. Sometimes the software/firmware in these boxes can "crash" and "re-booting" the box will solve the problem.
If you have a DVD/VCR or game system connected to the TV, you should also test whether have audio on the TV from any of these devices. Finally, if the TV has a headphone socket, try plugging in a set of headphones to check for audio. You may have accidentally switched the TV speaker off.
If you've done all of the above and you have no audio from any device or headphones, it's likely that the Main/AV board (motherboard) in the TV has failed and will need to be repaired or replaced.
Please try the suggestions above, then post back with the results for further assistance. Please include the model number of your TV. If you don't know the model number, this can usually be found on a label on the rear of the TV. You can reply to me by clicking on "Add a Comment" below your question.
Hope this helps - good luck!
