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.

Hi Wishmyremoteworked, Thank you for your feedback on the SolarCell Remote. If you’re having trouble with responsiveness, here are a few quick ways to check if it’s functioning correctly: 1. Test for infrared signal: Use your smartphone camera to look at the front of the remote. (If you're using an iPhone, the front-facing camera works best.) While pressing a button, you should see a flashing light through the camera. This confirms the remote is sending a signal. 2. Pairing: If the infrared is working, but the TV isn’t responding, make sure your remote is properly paired with your TV. 3. Charging: If no light appears, the remote may need to be charged. Plug a USB-C cable into the port at the bottom, or place the remote solar-side up in a well-lit area to recharge. If these steps don’t help, please contact Samsung Support so we can assist further. Call 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week, or connect via LiveChat by visiting the ‘Support’ section on our website. ~ Samsung Advisor
