Hi Dimps, Thank you for purchasing the new Samsung DU8000 TV and for providing us with feedback on the picture quality. I have a few troubleshooting steps for you to try that may resolve any image issues you are seeing. First, let's run a picture test to ensure it is not a connected device or app you are using that is causing the issue. Go to Home> Left directional button> Settings> Support> Device Care> Self Diagnosis> Picture Test. Next, there are several picture settings available, allowing you to adjust the image, including Picture Mode, Contrast, Brightness, and Sharpness settings. Go to Settings> All Settings> Picture. If you continue to have issues, please call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week. LiveChat with an agent, as well as manuals, software, and warranty info, can be found at the ‘Support’ link on our Samsung website. ~ Samsung Advisor

Hi TVLADY, We appreciate your feedback regarding the screen abnormalities you’re seeing on your DU7200 TV. Please run a Picture Test to determine if the problem is caused by the TV. Picture Test displays a high-definition picture you can examine for flaws or faults. Go to Settings > Support > Device Care > Self Diagnosis > Picture Test. If this occurs on all sources and the picture test, this may require service. For help with setting up a service appointment, please contact Samsung Support at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week. Our LiveChat agents are also available by clicking on the ‘Support’ link on our website. ~ Samsung Advisor
