Hey @Mrkevin and @Haensenson ,
sorry to hear that this is happening to your TVs. Have you tried to run a Picture test to see if there is an issue with the TV? To do this head into the TV Settings> Support> Self Diagnosis> Picture Test. If the issue persists during the test or the TV failed this a repair will be required. Please contact our Support Team to get this arranged: https://www.samsung.com/uk/support/contact/
