Hi Harold, Thank you for purchasing Samsung’s U7900F TV and for sharing your feedback regarding low volume. To start, we recommend making sure your TV is running the latest firmware, as updates can include improvements to sound performance: Home > Settings > Support > Software Update If volume levels still seem too low, you can improve sound performance by adjusting a few key settings: Sound Mode: Navigate to: Settings > All Settings > Sound > Sound Mode • Standard: Balanced for everyday viewing • Optimized: Enhances effects and creates a more spacious sound • Amplify: Boosts mid and high tones, especially helpful if dialogue is difficult to hear Auto Volume: This feature helps maintain consistent volume levels across content and input sources. Turn it on under: Settings > All Settings > Sound > Expert Settings > Auto Volume = On You can also explore Expert Settings to fine-tune sound output with adjustments for Balance, Equalizer, and more.

Run a Picture Test to check for panel-related issues: Settings > Support > Device Care > Self Diagnosis > Picture Test 4. Perform a cold boot by holding the power button on your remote for about 10 seconds 5. Ensure your TV has the latest software installed: Settings > Support > Software Update If the issue continues after these steps, the TV may require service.
