Troubleshooting Distorted Audio From the TV Speakers - TV

Distorted audio may occur as a side effect of a feature, an issue with a certain audio 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.
