Customer Ratings & Reviews

Hi ElishaM,

We're sorry to hear about the issues you are experiencing with the operating system on your TV. Please ensure your TV is running the latest Firmware, version 1132.0. Go to Settings> Support> Software Update. If this firmware version is not yet available on your TV, 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.

Hi JohnP,

We’re sorry to hear you’re not fully satisfied with the picture quality on your Samsung U7900F TV. 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.

Hi Keelo22,

We appreciate you sharing details about the flickering you’ve noticed on your Samsung U7900 TV. This behavior may be related to energy-saving features or dynamic picture settings that adjust the screen brightness automatically.

Please try disabling the following features: Settings > All Settings > General & Privacy > Power and Energy Saving
• Brightness Optimization
• Energy Saving Solution
• Motion Lighting

If these are already off, check if Contrast Enhancer is enabled, which can also cause brightness to shift depending on content: Settings > All Settings > Picture > Expert Settings > Contrast Enhancer

To ensure optimal performance, please also confirm your TV is running the latest firmware: Settings > Support > Software Update > Update Now

We hope these steps help stabilize your screen brightness. If you continue to experience issues, please don’t hesitate to contact 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 AnthonyC,

Thank you for your feedback. Please know you can control multiple devices with your Samsung TV remote if they are connected via HDMI cable. If your Remote isn’t controlling your external device, please try the following:
1. Reset the Remote: Press and hold Return and Enter (center of the navigation pad) for more than 10 seconds. Then, re-pair the remote by pressing Return and Play/Pause simultaneously for at least 5 seconds, or until a message appears on screen confirming connection.
2. Check the Remote Battery: On your TV, go to: Home > left directional key > Settings > All Settings > General & Privacy > Remote Control
3. Ensure the Remote is Sending IR Signals: Use your smartphone camera to check for infrared. If you see a flashing light from the remote’s front when pressing a button, it’s working properly.
4. Enable Anynet+ (HDMI-CEC): This feature allows your remote to control HDMI-connected devices. To enable it:
Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC) = On
5. If the device doesn’t support HDMI-CEC, use the Universal Remote feature. First, confirm the external device is properly connected. Then go to: Home > left directional key > Connected Devices > Universal Remote Setup, and follow the prompts.

If the issue persists, please call Samsung Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. Our LiveChat agents are also available by clicking the ‘Support’ link on our website.

Hi DelaynieW,

Thank you for sharing your experience. Buffering during streaming is typically related to internet speed or signal strength. This can happen when your connection isn’t able to deliver data quickly enough for smooth playback.

We recommend the following steps to help improve streaming performance:
1. Use a 5GHz Wi-Fi connection, if available
2. Try a wired LAN connection for more stability
3. Reposition your router to minimize obstacles between it and the TV
4. Make sure your TV is running the latest firmware (Settings > Support > Software Update)
5. Run Device Care to optimize performance: Home > left directional key > Settings > Support > Device Care > Start Device Care

If buffering continues, you may want to contact your internet service provider to check your current speed or explore upgrade options.

If we can assist further, please call us at 1-800-SAMSUNG, available daily from 8AM - 12AM EST. You can also visit the Samsung website and click on ‘Support’ for:
• Live Chat
• Manuals, Software, & Warranty Info
