LG TV - Troubleshooting Sound But No Picture on an LG TV

  • Troubleshooting

At a Glance

If your LG TV produces sound OK but no picture, you can check the TV by performing an image test.
If you have a problem with the set-top box or with the cable, the sound may be produced OK, but not the picture. In this case, you may try resetting the set-top box to solve the problem.
If you don't see the text, such as the TV channel or HDMI port information as shown below when you turned on the TV, we recommend that you request a repair for further assistance.
