Hi Chuy, 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

Hi John, Thank you for your feedback on the Samsung U7900F TV. If the picture appears unclear, dull, or lacks definition, there are several settings you can adjust to improve clarity and overall image quality. Go to: Settings > All Settings > Picture > Expert Settings, and review these key settings: Picture Clarity Settings: While originally intended for motion handling, these can also impact overall clarity • Off: Disables motion enhancements • Auto: Automatically adjusts based on content • Custom: Lets you fine-tune: o Judder Reduction – Helps smooth out uneven motion o LED Clear Motion – Boosts sharpness in fast-moving content o Noise Reduction – Reduces distortion and enhances detail in lower-resolution sources Core Picture Settings • Brightness – Controls overall screen brightness • Contrast – Enhances the difference between bright and dark areas • Sharpness – Adjusts edge definition; closer to 20 increases detail • Color – Enhances depth and intensity of colors And don’t forget to check for the latest firmware, which may improve performance: Settings > Support > Software Update > Update Now These adjustments can make a noticeable difference in overall clarity.
