Customer Ratings & Reviews

Hi ChrisC,

Thank you for your review of the Samsung U7900 TV. A light popping or clicking sound may occasionally be heard due to the natural expansion and contraction of the TV’s outer casing as it warms up or cools down.

Please know that this is not a defect and does not indicate a malfunction. It’s a normal part of the TV’s operation, and your TV remains completely safe to use.

If you have any other questions, we’re here to help - please contact Samsung Support at 1-800-SAMSUNG, available daily from 8AM - 12AM EST. You can also visit the Samsung website and click on ‘Support’ for:

Hi KyleM,

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 MisterJ,

We’re sorry to hear you’re not fully satisfied with the picture quality on your Samsung U7900 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 AliciaH,

Thank you for your review and for sharing your experience with audio interruptions on your U7900 TV. If you're experiencing sound issues such as crackling, the steps below are designed to help you troubleshoot across different connection types.

HDMI ARC / eARC Connection
1. Use a certified High-Speed HDMI cable with Ethernet and ensure it's firmly connected to the HDMI eARC ports on both the TV and soundbar/receiver.
2. Enable ARC/eARC settings on your TV:
o Settings > All Settings > Sound > Expert Settings > HDMI eARC Mode = Auto
o Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC) = On
3. Adjust Digital Output Audio Format:
o Settings > All Settings > Sound > Expert Settings > Digital Output Audio Format
o Set this to Auto unless you're using a device that specifically requires Pass-Through.
4. Cold boot your TV by holding the power button on your remote for 5+ seconds.

Bluetooth Connection
1. Bluetooth connections can be sensitive to distance and interference. Keep the Bluetooth device close to the TV, and remove nearby sources of interference (e.g., wireless routers or other Bluetooth devices).
2. For improved stability, use a 5GHz Wi-Fi network if available.
3. If issues persist, we recommend switching to a wired connection (HDMI ARC or Optical) for a more reliable audio experience.

Wi-Fi / Wireless Speaker Connections
1. Make sure both your TV and audio device are on the same network band (5GHz is ideal for stability).
2. If you're using Samsung’s Wireless Audio features (e.g., Wi-Fi Speaker Surround Setup), ensure your speaker system is properly added in: Settings > All Settings > Sound > Sound Output > Wi-Fi Speaker Surround Setup
3. If signal issues continue, disconnect and reconnect the speaker from the network and re-add it to the TV.

Also Try:
• Update your TV's firmware: Settings > Support > Software Update > Update Now
• Run a Sound Test to verify internal sound functions: Settings > Support > Device Care > Self Diagnosis > Sound Test

Hi TimothyB,

Thank you for your feedback on the lip sync issues you're experiencing with your Samsung U7900 TV. This may be related to the content source, but if you're noticing the audio delay across all sources or channels, especially when using an external speaker setup (soundbar, receiver, etc.), there are a few settings that may help:

1. Adjust Digital Audio Delay. You can manually increase the audio delay to better match the video: Settings > All Settings > Sound > Expert Settings > Digital Output Audio Delay

2. Enable Audio Pass-Through. Samsung TVs include an audio pass-through option, which sends the audio signal directly to your connected soundbar or receiver without additional processing by the TV. This can reduce delay when using external audio devices: Settings > All Settings > Sound > Expert Settings > Digital Audio Output Format > Pass-Through

3. Check for Firmware Updates. Ensure your TV is running the latest software, which may include performance improvements related to sound or sync: Home > left directional key > Settings > Support > Software Update > Update Now

If the issue continues after these steps, please contact Samsung Support for additional troubleshooting or assistance. We’re here to help 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.
