Understanding the Possible Causes
Before we dive into the troubleshooting process, it’s essential to understand the possible causes of the issue. Here are some of the most common reasons why your Hisense TV might have sound but no picture:
Loose or Faulty Connections
One of the most common causes of this issue is a loose or faulty connection between the TV and the external devices connected to it, such as a cable box, DVD player, or gaming console. If the connections are loose, it can cause the picture to disappear while the sound remains.

Hardware Issues
Hardware issues, such as a faulty backlight or a damaged screen, can also cause the picture to disappear while the sound remains. In some cases, the issue can be caused by a faulty motherboard or a malfunctioning graphics card.
Software Issues
Software issues, such as a corrupted operating system or a faulty firmware, can also cause the picture to disappear while the sound remains. In some cases, the issue can be caused by a conflict between the TV’s software and the software of the connected devices.
