Big-screen televisions can be adjusted for picture. Basic picture settings that are user customizable include the brightness, contrast, color, tint and sharpness. Some televisions feature advanced video settings that can include adaptive contrast, dynamic contrast, color temperature and more. Once you've verified that the television is plugged in and turned on, you can perform some settings changes that will fix the problem.

Step 1

Press the "Menu" or "Setup" button on the remote control and look for a menu item labeled "Picture" or similar. Use the arrow keys to scroll to the option labeled "Restore Picture Settings," "Restore Factory Defaults" or similar. Select it using the "OK" or "Enter" button. The original factory settings will be restored, and if you view a television program the brightness should be acceptable.

Step 2

Make changes to the "Brightness" setting if the picture is still too dark. Scroll to "Brightness" and using the arrow keys move the on-screen slider to adjust it. Try the television again.

Step 3

Make changes to some of the advanced settings if you continue to have problems. Look for a setting called "Advanced Video" or similar. Look for any settings related to contrast. "Adaptive Contrast" automatically adjusts picture detail related to brightness, and "Dynamic Contrast ratio" enhances the contrast ratio between light and dark areas on the picture. Make changes to those settings with the slider and check the results by viewing a program.

Step 4

Place the television out of direct sunlight, and pointing away from windows, if you continue to have problems.
