Hhisense lcd tv has lost its volume

Hisense is a relatively new Chinese TV brand, and the first couple I owed all had audio problems. A sharp chirp was emitted every time a switched from an HD channel to normal resolution.

1. Try different sources to see if audio comes through on those devices. If so, it could very well be something simple like a muted device.

2. If you pipe everything through a receiver, check the volume options there first before you start throwing things out the window. If you own a small gnawing animal, check speaker cables to see if they still go places.

3. If all 3rd party device possibilities have been ruled out, open up the menu and explore the audio options for the TV itself.

4. If all else fails and you're ready to turn this thing into a pile of glass, try a factory reset. You can find this option by going to Menu > System > Factory Reset.
