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

Hi Old guy, Thank you for your feedback regarding the screen abnormalities you're seeing on your TV. To help determine if the issue is related to the panel itself, we recommend starting with a Picture Test, which displays a high-definition image you can examine for flaws: Settings > Support > Device Care > Self Diagnosis > Picture Test If the issue appears during the test and across all sources (built-in apps, HDMI devices, etc.), it may indicate a panel-related concern. You can also try displaying solid-color test videos (red, green, blue, black, white) from a USB drive or YouTube. This can help you identify whether any pixels are stuck or not functioning properly. In some cases, unplugging the TV for a few minutes and rebooting it can help resolve stuck pixels caused by temporary display behavior. If the problem persists after these steps, the TV may require service. To set up a service appointment, please contact Samsung Support 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
