kpkp, Thank you for sharing your feedback with us. To help you get the most from your TV, you can download the full e-Manual and more by visiting Samsung’s website, then navigating to: Support > Manual & Software > TVs & Home Theater. From there, you can search for and select your U7900F TV model to view or download the available guides. The e-Manual & User Guide are also conveniently built into your TV: Settings > Support > Tips and User Guides. Your TV includes Learn Menu Screen, an accessibility feature that provides audio guidance for on-screen menus. When enabled, your TV will announce the name and function of each menu item as you scroll, without making any changes. This feature is particularly helpful for users who are visually impaired or new to Smart TV menus. To enable, go to: Settings > All Settings > General & Privacy > Accessibility > Learn Menu Screen. To exit, press the Return key twice. If you’d like more assistance with this feature, please reach Samsung Support at 1-800-SAMSUNG, available 8AM – 12AM EST, 7 days a week.

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
