Hi Not impressed, Thank you for sharing your experience with your U8000H TV. If you’re hearing no sound or the sound occasionally drops and you’re not using any external devices like a soundbar or receiver, the following steps may help restore or stabilize your TV audio: 1. Check your Sound Output. Make sure the TV is set to use its internal speakers: Home > left directional key > Settings > All Settings > Sound > Sound Output > TV Speaker 2. Run a Sound Test. This will help determine whether the issue lies with the TV’s speakers: Settings > Support > Device Care > Self Diagnosis > Sound Test. If you don’t hear audio during the Sound Test, the TV may require service. 3. Cold Boot the TV. This will refresh the system and can resolve temporary audio glitches. With the TV on, press and hold the Power button on the remote until the TV turns off and back on. Alternatively, unplug the TV from power for 30 seconds, then plug it back in. 4. Reset Sound Settings. If sound settings were changed or became corrupted, you can reset them to factory defaults: Settings > All Settings > Sound > Expert Settings > Reset Sound 5. Check for Firmware Updates. Software updates can improve audio performance and fix known issues: Settings > Support > Software Update > Update Now If the issue persists after trying the steps above, we recommend contacting Samsung Support for further assistance. You can reach us at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat agents are also available through the ‘Support’ link on our website. ~ Samsung Advisor
