Hi Slygawd, 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 > Home > left directional key > Settings > Support > Software Update > Update Now We hope these tips help improve your viewing experience.

Hi TOzone, Thank you for sharing your experience with your U7900F TV. If you're not hearing sound or if the sound cuts out and you're using only the TV’s built-in speakers (no soundbar or external device), try the following steps: 1. Check volume and mute settings, and make sure the Sound Output is set to TV Speaker: Settings > All Settings > Sound > Sound Output > TV Speaker 2. Run a Sound Test to help diagnose the issue: Settings > Support > Device Care > Self Diagnosis > Sound Test 3. Cold boot your TV by holding the power button on the remote until the TV turns off and back on (Or unplug the TV from power for 30 seconds, then plug it back in) 4. Reset sound settings to default: Settings > All Settings > Sound > Expert Settings > Reset Sound 5. Update your TV’s software in case a firmware issue is affecting audio: Settings > Support > Software Update > Update Now If none of these steps restore your sound, please contact us for further assistance.
