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 Jselover, We’re sorry to hear that the picture on your Samsung U7900F TV appears too dark. If this isn’t meeting your expectations, there are several settings you can adjust to improve the overall brightness and clarity of your screen. First, try disabling certain energy-saving features that may be dimming the screen automatically. 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. Next, adjust the Picture Mode to better match your viewing environment: Settings > All Settings > Picture > Picture Mode and choose from the following: • Dynamic – Brighter and clearer for well-lit rooms • Standard – Balanced for most environments • Movie – Ideal for watching in a dark room • Eco – Designed for energy savings • Filmmaker Mode – Preserves the creator’s original intent You can also manually adjust brightness by going to: Settings > All Settings > Picture > Expert Settings > Brightness. Use the slider to set a level that suits your preferences (0–50). Finally, we recommend making sure your TV has the latest software installed: Settings > Support > Software Update > Update Now We hope these tips help improve your viewing experience.
