Hi JanMar, Thank you for your feedback regarding the screen abnormalities you’re seeing on your Samsung U8000F TV. To determine whether the issue is related to the TV itself, we recommend running a Picture Test, which displays a high-definition test image for you to examine. Go to: Settings > Support > Device Care > Self Diagnosis > Picture Test If the issue appears on all sources and during the Picture Test, the TV may require service. For help setting up a service appointment, please contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun), or reach us via text anytime. You can also visit ‘Support’ on our website for: • Live Chat • Manuals, Software, & Warranty Info ~Samsung Advisor
