Hi Enimom, We’re sorry to hear your U8000F TV is turning off on its own. Please try the following troubleshooting steps which may help resolve the issue: 1. Unplug the TV from the wall outlet or surge protector for at least 30 seconds. 2. Inspect the power cord for any visible damage. If damaged, the cord may need to be replaced. 3. Plug the TV directly into a wall outlet, bypassing any power strip or surge protector for now. 4. If the TV remains on long enough, try updating the TV’s software: Home > left directional key > Settings > Support > Software Update > Update Now. Note: If your TV powers off during the update, it could result in damage, so only proceed if the TV is stable. Next, check the TV’s Power and Energy Saving settings to ensure no timers or auto-off features are enabled: • Sleep Timer: Settings > All Settings > General & Privacy > Power and Energy Saving > Sleep Timer • Auto Power Off and Off Timer: Settings > All Settings > General & Privacy > Power and Energy Saving > Auto Power Off/Off Timer Also, if you have devices connected via HDMI, check if Anynet+ (HDMI-CEC) is enabled, as this can allow external devices to control the TV and may cause it to turn off: Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC) = Off If your TV continues to power off unexpectedly, please call us at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).

Hi Jax24, Thank you for sharing your experience with volume fluctuations on your Samsung U8000F TV. Sudden changes in volume can often be related to audio settings or content differences between sources or apps. Please try the following adjustments to help stabilize your TV's audio: 1. Enable Auto Volume. Go to: Settings > All Settings > Sound > Expert Settings > Auto Volume. This feature helps maintain a consistent volume level when switching channels or apps. 2. Change 3. . Try a different sound mode to see if one offers a more stable output: Settings > All Settings > Sound > Sound Mode (We recommend Standard or Amplify for more even performance.) 4. Check External Devices. If you're using a soundbar, receiver, or other audio device, check that its volume leveling or dynamic range settings aren’t interfering with the TV’s audio. 5. Update Firmware. Ensure your TV is running the latest software, as updates may include audio improvements: Settings > Support > Software Update > Update Now If the issue persists after these steps, please don’t hesitate to reach Samsung Customer Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat is also available via the ‘Support’ link on our website. ~ Samsung Advisor
