Hi Greyed A, Thank you for your purchase and for the video of the image issues you are having with your new DU8000 TV. I have put a few troubleshooting steps for you to try before calling Customer Support for a warranty appointment. First, if you have any cables connected to your TV, please double-check that they are securely inserted. Next, there are energy efficiency features designed to reduce power consumption that may be causing the flickering. Go to Settings > All Settings> General > Power and Energy Saving > and adjust the Brightness Optimization, Brightness Reduction, and Motion Lighting. Finally, I recommend running a picture test to ensure it is the TV, not the program source. Go to Home > Settings > Support > Device Care > Self Diagnosis > Picture Test. 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 Not Great, I'm sorry your DU8000 TV is randomly shutting itself off. If your TV appears to turn off by itself, try disabling some of the TV's energy efficiency functions. See if the Sleep Timer has been enabled. The Sleep Timer automatically turns the TV off after a specific period of time. Go to: Settings > All Settings> General > System Manager > Time > Sleep Timer If the Sleep Timer has not been enabled, see if Auto Power Off or Off Timer has been enabled and disable it. - Settings > All Settings> General > Power and Energy Saving > Auto Power Off - Settings > All Settings> General > System Manager > Time > Off Timer If the TV continues to turn off by itself continuously, please get in touch with Samsung Customer 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
