Why Does Your LG TV Have Sound but No Picture?

Why does my LG TV turn on, but the screen is black? There are several reasons why your LG TV has a black screen, yet the sound is audible.

Here are common reasons your LG TV might give sound but no picture:

  • Damaged TV panel: Another possible reason your LG LED smart TV has sound, but no pictures can be a damaged screen. If your TV has a damaged screen, you’ll hear the background sound, but no pictures will be on display. A faulty screen can result from an electrical surge or extreme temperature.
  • Power failure on the LG TV power supply board: Your TV’s power supply board allows you to view images on the screen. If the supply board fails, your TV won’t display pictures but will have sound.
  • Problem with connections: If your LG LED TV has no picture but has sound, investigate whether there are loose connections or damaged cables. When the cable responsible for displaying images is loose or damaged, your TV will have no pictures despite having sounds.
  • TV settings: Your LG LED TV might fail to display pictures if someone tampered with it. Perhaps a family member changed it to LG TV audio-only mode without your knowledge, allowing you to hear the sound but no picture.  

Now you know the possible causes of an LG LED TV with no picture but sound. So, what do you do if your TV has sound but no picture?
