Why does my Sharp LC-40LB480U have good picture but no sound?

If your Sharp TV has good picture but no sound, first increase the volume and ensure the sound isn't muted. Check that the correct audio mode is selected and the audio cables are securely connected to the TV. Also, make sure the antenna or cable TV is correctly and securely connected. If you are using an antenna, the digital channel signal may be low. To check the digital channel signal strength, see “Checking the digital signal strength” on page 52. The audio cables you are using may be faulty, so try a new set.
