Audio Systems: No more audio from TV, tv speakers, lg tv

Question
I have an LG TV. I bought a sound bar because it was so hard to hear the TV speakers, since they are located in the back. My sound bar went out and I had to use the TV speakers. I had to turn the volume up so loud just to hear regular programming. Once the TV was on for a bit, it almost sounded as though the speakers had "blown" with a lot of vibration and rattle. I know have a new sound bar and all was working well...until this morning. My wife sent me a text telling me that there was no volume on the TV. When I got home I checked it out, and sure enough, there is no volume at all. No volume coming from the sound bar and no volume at all coming from the TV speakers when I turn it up. Things had been working fine before this morning. I don't know if the volume has completely gone out on the TV, and therefore not sending volume to the sound bar or what. I am at a loss...any help would be appreciated. Thank you for your time.

Answer
Hi Paul,

This is definitely something you'll need to bring up with LG. If you're not getting any volume from the TV by itself (without the sound bar plugged in), it sounds like something pretty seriously wrong and "above my pay grade" to assess online.
