Hi Tvbuff, We’re sorry to hear you’re not fully satisfied with the picture quality on your Samsung U8000F 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. If you need further support, feel free to contact us at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat is also available via the ‘Support’ link on our website. ~ Samsung Advisor

Hi there, We're sorry to hear about the color issues you are experiencing on your TV. Please ensure your TV is running the latest Firmware, version 1132.0. Go to Settings> Support> Software Update. If this firmware version is not yet available on your TV, you can download the update on a USB drive and manually update your TV: 1. On Samsung's website (upper right corner), go to: Support > Manual & Software > Find your TV model, and click on the Firmware – Upgrade File. 2. When the file has finished downloading, locate it and then unzip it. There is normally one folder inside but there may be multiple files. 3. Copy or move all of the files that were included in the zip file to a USB flash drive, but do not place them inside any other folders. If you place the software folders inside a folder on the USB flash drive, the TV or monitor will not find them. 4. Connect the USB drive containing the software upgrade into a USB port on your device. 5. Using your device's remote, navigate to and select Settings, then select All Settings, and then select Support. Select Software Update, select Update Now, and then select Yes if prompted. Your device will search the USB drive for update files. Follow the on-screen instructions to install the updated software. Updates usually take a few minutes; please do not turn off the TV until the update is complete. When the update is finished, it will restart automatically. If you need additional support, Samsung is here to help. Please call us at 1-800-SAMSUNG, available daily from 8AM - 12AM EST. You can also chat with a LiveChat agent by clicking the ‘Support’ link on our website. ~ Samsung Advisor
