A:AnswerHi Stef,
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 – 12AM EST, 7 days a week. LiveChat and additional support resources are also available through the Support link on our website.

A:AnswerHi,
If the image appears too dark, we suggest disabling certain energy-saving features, which can automatically adjust brightness and affect how the screen looks.
Go to: Settings > All Settings > General & Privacy > Power and Energy Saving, then turn off Brightness Optimization, Energy Saving Solution, Motion Lighting, and/or Contrast Enhancer.
You can also adjust the Picture Mode to better suit your environment: Settings > All Settings > Picture > Picture Mode
• Standard – Default mode for general viewing
• Dynamic – Brighter and clearer, ideal for well-lit rooms
• Movie – Best for dark room viewing
• Eco – Energy-saving mode
• Filmmaker Mode – Preserves content as intended by creators
To fine-tune brightness, go to: Home > left directional key > Settings > All Settings > Picture > Expert Settings, then adjust the Brightness level (0–50) to your preference.
Lastly, please make sure your TV is running the latest firmware: Home > Home > left directional key > Settings > Support > Software Update > Update Now
We hope these tips help improve your viewing experience. If you need further support, feel free to contact us at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat is also available via the ‘Support’ link on our website.

A:AnswerHi JM,
Verizon Cable is not included with the U7900 TV. However, it is not an additional cost to connect to a cable box outside of the cable subscription fee, cable boxes, and cables.

A:AnswerHi Andy,
Yes, you can disable the Smart Features, or when prompted, choose not to sign into a Samsung account, which will prevent any Smart Features from being accessed.
I hope this helps!
