Troubleshooting Dark or Dim Picture - TV

Dark or dim picture may occur as a side effect of a feature, an issue with a certain video/input, or in rare cases there may be an issue with the TV. Start by choosing your TV type from the images below, then follow some troubleshooting steps to resolve the issue.


Press the Smart  button on your remote,
then click on the image below that matches your screen.

(webOS and webOS 2.0 have a subtle difference in the top-right,
move your mouse over an image to zoom)

If you do not have a Smart Button, choose HDTV.



The Picture Test option will display a test image on the TV, and you will decide if it is displayed correctly. To access the Picture Test:

  1. Press the Home/Smart  button on your remote, then click the Settings icon in the top-right.

  1. Is the image dark/dim during the Picture Test?
    (If your TV doesn't have a Picture Test, choose Yes) Yes No
  2. The Picture Test runs with optimized picture settings. If the image was still dark/dim, try the following:

    • Set the Backlight and Brightness to high values, such as 100. Access the backlight/brightness settings from the Picture Mode Settings.
    • The lighting in your room can be a strong factor in perceived brightness. Try closing any blinds, shades, curtains, etc. and see if the picture improves.
    • If the issue persists, Contact Us.
  3. The Picture Test runs with optimized picture settings. If the image was not dark/dim during the test, your picture settings are likely the cause. Try the following:

    • Navigate to Settings > Picture.
    • Use the Picture Wizard feature for the easiest, most reliable way of configuring your Picture Settings.
    • Make sure Smart Picture Mode is set to Off.
    • Try some of the pre-set Picture Modes, such as Vivid, Cinema, or Game.
    • If none of the pre-set modes provide a desirable picture, try to adjust the Energy Saving mode. Setting this to Minimum or Off may improve the brightness (though it will consume more power).
    • Try to adjust your Picture Settings manually by accessing the Picture Mode settings sub-menu. Increase the backlight, brightness, and contrast.
    • If all else fails, choose Reset at the bottom of the Picture Mode Settings menu, then try again.
    • The lighting in your room can be a strong factor in perceived brightness. Try closing any blinds, shades, curtains, etc. if the picture is not improving enough when adjusting the settings.
