Degaussing demagnetizes the metal components in your TV and minimizes the potential for image distortion. Although most televisions, including Sony televisions, degauss automatically, there are times when you must manually force the TV to degauss. A degauss is required when you notice image distortion and color issues, especially around the edges. Forcing a degauss in a Sony TV is straightforward. However, if image distortion and color issues persist, you might consider purchasing a brand-new television (link in Resources). Tips Warnings Writer Bio
