Customer Ratings & Reviews

Hi RobertA,

Thank you for your feedback. Please ensure your U7900 TV is running the latest firmware update 1132.0. To do so, go to Settings> Support> Software Update. If that version is not available you can download the update on a USB drive and manually update your TV:

1. On Samsung's website (upper right corner), go to: Support > Manual & Software > Find your TV model, and click on the Firmware – Upgrade File.
2. When the file has finished downloading, locate it and then unzip it. There is normally one folder inside but there may be multiple files.
3. Copy or move all of the files that were included in the zip file to a USB flash drive, but do not place them inside any other folders. If you place the software folders inside a folder on the USB flash drive, the TV or monitor will not find them.
4. Connect the USB drive containing the software upgrade into a USB port on your device.
5. Using your device's remote, navigate to and select Settings, then select All Settings, and then select Support. Select Software Update, select Update Now, and then select Yes if prompted.

Your device will search the USB drive for update files. Follow the on-screen instructions to install the updated software. Updates usually take a few minutes; please do not turn off the TV until the update is complete. When the update is finished, it will restart automatically.

If you need additional support, Samsung is here to help. Please call us at 1-800-SAMSUNG, available daily from 8AM - 12AM EST. You can also chat with a LiveChat agent by clicking the ‘Support’ link on our website for:

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.
