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).
