Customer Ratings & Reviews

Hi user381725,

Thank you for your review. While your U7900 TV may currently default to Samsung TV Plus when powered on, you can customize what your TV does at startup by adjusting the Start Screen Options.

To do this, navigate to: Settings > All Settings > Advanced Features > Start Screen Option and choose from the following:
1. Start with Smart Hub Home – Automatically launches Smart Hub when the TV is turned on. You can enable or disable this option based on your preference.
2. Autorun Multi View Casting – If you cast YouTube content from your mobile device, the TV will automatically display the content using Multi View.
3. Autorun Multi View Mirroring – When you screen mirror your mobile device, Multi View will automatically open to show your device’s screen.

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 Sound Mode. 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.)
3. 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.
4. 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 – 12AM EST, 7 days a week. LiveChat is also available via the ‘Support’ link on our website.

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