Before we dive into the solutions, it’s essential to understand the possible causes of a darkening Vizio TV screen. Here are some of the most common reasons:
Backlight Issues
The backlight is a critical component of your Vizio TV, responsible for illuminating the LCD panel. If the backlight is faulty or failing, it can cause the screen to appear darker than usual. There are several reasons why the backlight might be malfunctioning, including:

- Loose connections: If the connections between the backlight and the TV’s motherboard are loose, it can cause the backlight to malfunction.
- Backlight driver failure: The backlight driver is responsible for controlling the backlight’s brightness. If it fails, the backlight may not function correctly.
Picture Settings
Sometimes, the issue might not be with the TV’s hardware but with the picture settings. Here are a few scenarios:
- Incorrect picture mode: If you’re using a picture mode that’s not suitable for your viewing environment, it can cause the screen to appear darker than usual.
