2. In TV settings, find "Restore Factory Settings" and click Wait for a while to finish restoring factory settings. It should be noted that after the factory settings are restored, all downloaded third-party software and local files will be deleted, and they can be backed up in Dangbei Market Management-Cloud Backup before the factory settings are restored.
