Hi JayJay, Thank you for sharing your experience with volume fluctuations on your Samsung U7900F TV. 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 – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun. LiveChat is also available via the ‘Support’ link on our website. ~ Samsung Advisor

Hi Tanny, We’re sorry to hear that the picture on your Samsung U7900F TV appears too dark. If this isn’t meeting your expectations, there are several settings you can adjust to improve the overall brightness and clarity of your screen. First, try disabling certain energy-saving features that may be dimming the screen automatically. 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. Next, adjust the Picture Mode to better match your viewing environment: Settings > All Settings > Picture > Picture Mode and choose from the following: • Dynamic – Brighter and clearer for well-lit rooms • Standard – Balanced for most environments • Movie – Ideal for watching in a dark room • Eco – Designed for energy savings • Filmmaker Mode – Preserves the creator’s original intent You can also manually adjust brightness by going to: Settings > All Settings > Picture > Expert Settings > Brightness. Use the slider to set a level that suits your preferences (0–50). Finally, we recommend making sure your TV has the latest software installed: Settings > Support > Software Update > Update Now We hope these tips help improve your viewing experience.
