Hi Mary, Thank you for your feedback. If your remote isn’t responding, here are a few quick steps to help determine if it’s working correctly: 1. Check the batteries: Remove the back cover of your remote and replace the batteries with a fresh set, ensuring they are inserted in the correct direction. 2. Test for infrared signal: Point the front of the remote at your smartphone camera. While holding down any button, you should see a flashing light through the camera screen. (For iPhone users, the front-facing camera works best.) If you see the light, your remote is working and may need to be re-paired with your TV. 3. Point the remote correctly: Try pointing the remote directly at the TV from about 5-6 feet away. This can help ensure a clearer signal between the remote and the TV.

Hi Sandy, We’re sorry to hear you’re not fully satisfied with the picture quality on your Samsung U7900F TV. If the image appears too dark, we suggest disabling certain energy-saving features, which can automatically adjust brightness and affect how the screen looks. Go to: Settings > All Settings > General & Privacy > Power and Energy Saving, then turn off Brightness Optimization, Energy Saving Solution, Motion Lighting, and/or Contrast Enhancer. You can also adjust the Picture Mode to better suit your environment: Settings > All Settings > Picture > Picture Mode • Standard – Default mode for general viewing • Dynamic – Brighter and clearer, ideal for well-lit rooms • Movie – Best for dark room viewing • Eco – Energy-saving mode • Filmmaker Mode – Preserves content as intended by creators To fine-tune brightness, go to: Home > left directional key > Settings > All Settings > Picture > Expert Settings, then adjust the Brightness level (0–50) to your preference. Lastly, please make sure your TV is running the latest firmware: Home > left directional key > Settings > Support > Software Update > Update Now We hope these tips help improve your viewing experience. If you need further support, feel free to contact us at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat). LiveChat is also available via the ‘Support’ link on our website. ~ Samsung Advisor
