Hi Gray, We’re sorry to hear your remote isn’t working as expected. Please try the following troubleshooting steps, which may help: 1. Check and clean the top edge of the remote. Dust or smudges on the IR sensor at the top of the remote can interfere with performance. Gently wipe the sensor area with a clean, dry microfiber cloth. 2. Replace the batteries. Weak or depleted batteries can cause erratic behavior. Insert a fresh set of batteries and make sure they are positioned correctly in the battery compartment. 3. Check for available software updates. Occasionally, remote responsiveness issues can be resolved with a firmware update to the TV. Go to: Settings > Support > Software Update > Update Now 4. Ensure there are no nearby devices interfering with the signal. Nearby electronics (like soundbars, game consoles, or even sunlight hitting the IR sensor) may interfere with your remote's signal. Try using the remote with other nearby devices powered off. If the issue continues after trying these steps, please reach out to Samsung Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. Our LiveChat agents are also available by clicking the ‘Support’ link on our website. ~ Samsung Advisor

Hi Skyventor85, Thank you for your feedback. For optimal performance, please ensure your TV is running the latest firmware Update Version 1269.9. You can check this by going to: Home > left directional key > 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 continue to have issues, please call us at -800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat support and additional help are available at the ‘Support’ link on our website. ~ Samsung Advisor

Hi Thomas, Thank you for sharing your thoughts on the available inputs for the U8000F. Your TV has 3 HDMI ports and is Bluetooth-enabled. If an Optical port is a crucial part of your setup needs, you’ll find that connection starting with our Q8F Series and above. Should you ever need assistance with your TV, Samsung is here for you. Reach out by calling 1-800-SAMSUNG between 8AM - 12AM EST, any day of the week. You can also chat with us online by visiting the ‘Support’ section of our website. ~Samsung Advisor
