  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.

  Travis MunozAug 26, 2025
  If one or more channels do not display on your Sharp TV, ensure the channels are not blocked by checking parental control settings. Also, verify the channels are not hidden, as they may have been deleted from the channel list. You can tune to the channel by pressing the number buttons or add the channel back to the channel list. If you are using a cable or satellite box, use the remote that came with that box to change channels and make sure that you have the correct input selected to view channels from the cable or satellite box. If you are using an antenna, the digital channel signal may be low, so check the digital channel signal strength.

  If, after running Auto Channel Search on your Sharp TV, there are no channels, reception can vary by channel depending on the broadcast power level of a given station. Contact your cable or satellite TV provider. Make sure that the antenna or cable/satellite TV is connected securely to your TV. Try replacing the cable between the antenna/cable or cable/satellite box and your TV.
