Hi Madbuck, Thank you for your feedback. If the latest firmware version 1132.0 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 1-800-SAMSUNG (8AM – 12AM EST, 7 days a week), or connect with a LiveChat agent by selecting ‘Support’ on our website. ~ Samsung Advisor

Hi FakeCakes, Thanks for sharing your experience. If your TV is powering on by itself, there are a few settings and external triggers to review: 1. Power On with Mobile – Your TV may be connected to the SmartThings app or other networked devices. To stop wake signals, turn this feature off: Settings > All Settings > Connection > Network > Expert Settings > Power On with Mobile = Off 2. Check for Active Timers – Go to Settings > All Settings > General & Privacy > System Manager > Time > Timer Settings, then disable any On Timers or Sleep Timers 3. Anynet+ (HDMI-CEC) – If your TV is connected to external HDMI devices, one of them may be triggering power-on behavior. To disable this feature: Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC) = Off 4. Software Update – Make sure your TV is up to date: Settings > Support > Software Update > Update Now If you’ve ruled out all the above and your TV still powers on unexpectedly, try unplugging it for 30 seconds. Should the issue continue, please call Samsung Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat agents are also available by clicking the ‘Support’ link on our website. ~ Samsung Advisor

Hi Cab15, We appreciate your feedback on the inputs available on the U7900F TV. Although there is not a One Connect Box available for this TV Series, you can utilize an HDMI splitter to increase the amount of ports available. I hope this helps! If you have any questions or need help, we’re always here. Call 1-800-SAMSUNG from 8AM - 12AM EST, seven days a week, or connect with a LiveChat agent anytime by selecting ‘Support’ on our website. ~ Samsung Advisor
