Hi DH Ladd, Thank you for sharing your experience. We’re sorry to hear your U7900F TV is turning on and off unexpectedly. This kind of power cycling can often be resolved with a few troubleshooting steps: 1. Check the power cable for secure connection and signs of damage. If it’s bent, pinched, pressed by furniture, or shows wear, replacing it may resolve the issue. 2. Unplug the TV from the wall outlet for 30 seconds, then plug it back in and test operation. 3. Update the TV’s software (if the TV remains on long enough). Note that a power interruption during an update can cause further issues, so only proceed if the TV is staying on reliably. Go to: Settings > Support > Software Update > Update Now 4. If your TV is connected to SmartThings, it may be turning on from a signal sent through the network. You can disable this feature by going to: Home > left directional key > Settings > All Settings > Connection > Network > Expert Settings > Power On with Mobile = Off If none of these steps resolve the issue, your TV may need service. Please give us a call at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). Our LiveChat agents are also available at the ‘Support’ link on our website. ~ Samsung Advisor

Hi Sheebs, Thank you for sharing your review. Please know you can control your connected devices (like cable boxes, Blu-ray players, or game consoles) using your U7900FD TV’s remote by following these steps: 1. Connect & Power On the Device Connect the external device to one of your TV’s HDMI ports and power it on. Your TV may automatically detect the device and switch inputs. If it doesn’t, continue with the steps below. 2. Launch Universal Remote Setup. On your TV, navigate to: Home > left directional key > Connected Devices > Universal Remote Setup. When the connected device appears, select it to begin setup. 3. Start the Setup. Select Universal Remote on the Home screen, choose Start, and ensure your device is powered on. When your desired device appears, select it and follow the on-screen instructions. Setup may vary slightly based on device type. 4. Finalize and Test. Once complete, your Samsung TV and remote will remember the connected device and its HDMI port. If the device doesn’t respond after setup, you may need to re-register it or adjust its position for better signal reception. Helpful Tips: • If your external device is a Samsung product, Anynet+ (HDMI-CEC) may let you control it automatically using your TV remote with no extra setup. • Make sure nothing blocks the IR signal between your TV and external devices. • If you’re having difficulty, try adjusting the device’s position for better remote signal reception. • This feature may not be supported on all external devices or setups. For further support with setup or compatibility questions, please don’t hesitate to contact Samsung Customer Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).
