Hi Ironhorserider, Thank you for your feedback. You mentioned already adjusting settings, but I am going to put a few suggestions below, just in case you have not tried these. 1. Adjust Digital Audio Delay. You can manually increase the audio delay to better match the video: Settings > All Settings > Sound > Expert Settings > Digital Output Audio Delay 2. Enable Audio Pass-Through. Samsung TVs include an audio pass-through option, which sends the audio signal directly to your connected soundbar or receiver without additional processing by the TV. This can reduce delay when using external audio devices: Settings > All Settings > Sound > Expert Settings > Digital Audio Output Format > Pass-Through 3. Check for Firmware Updates. Ensure your TV is running the latest software, which may include performance improvements related to sound or sync: Home > left directional key > Settings > Support > Software Update > Update Now If the issue continues after these steps, please contact Samsung Support for additional troubleshooting or assistance. We’re here to help at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat and additional support resources are also available through the Support link on our website. ~Samsung Advisor

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
