Hi Birdie Guy, 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 – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat agents are also available by clicking the ‘Support’ link on our website. ~ Samsung Advisor

Hi HBall, We’re sorry to hear that the picture on your Samsung U7900F TV appears too dark. If this isn’t meeting your expectations, there are several settings you can adjust to improve the overall brightness and clarity of your screen. First, try disabling certain energy-saving features that may be dimming the screen automatically. 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. Next, adjust the Picture Mode to better match your viewing environment: Settings > All Settings > Picture > Picture Mode and choose from the following: • Dynamic – Brighter and clearer for well-lit rooms • Standard – Balanced for most environments • Movie – Ideal for watching in a dark room • Eco – Designed for energy savings • Filmmaker Mode – Preserves the creator’s original intent You can also manually adjust brightness by going to: Settings > All Settings > Picture > Expert Settings > Brightness. Use the slider to set a level that suits your preferences (0–50). Finally, we recommend making sure your TV has the latest software installed: Settings > Support > Software Update > Update Now We hope these tips help improve your viewing experience. If you need further assistance with setup or adjustments, feel free to contact Samsung Customer Support at -800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).
