Hi Charlie, 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.

Hi Pat from FL, I'm sorry for any confusion about controlling your Samsung DU7200 TV with a voice remote. You are correct; the DU7200 does not have voice assistants built in. However, they do work with Alexa. You can connect them to your existing Alexa device to ask them to turn on your TV, change channels, control volume, and more. Our DU8000 TV Series and above offer voice command and built-in voice assistants. If you need assistance connecting your external Alexa device or if there’s anything we can ever help with, please call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week. Or visit us on the Samsung website and click on the ‘Support’ link for: 1) LiveChat 2) Manuals, Software, & Warranty Info ~ Samsung Advisor
