At a Glance
In the event that your LG TV produces sound but fails to show a picture, potential causes could include a loose or faulty cable, incorrect input settings, or, in rare instances, a TV malfunction.
If your home theater or receiver serves as a central hub for all external devices connected to the TV, make sure that the TV is set to the same input as the home theater.
Additionally, ensure that the home theater is set to output from the external device connected to it. If you are unfamiliar with how to operate the function/input settings of your home theater or receiver, you may need to directly connect the external device to the TV.
