Run a Picture Test to check for panel-related issues: Settings > Support > Device Care > Self Diagnosis > Picture Test 4. Perform a cold boot by holding the power button on your remote for about 10 seconds 5. Ensure your TV has the latest software installed: Settings > Support > Software Update It is also possible that the TV was damaged during transit, if care was not taken.
