Hi Costco shopper, Thank you for your feedback. If your remote isn’t responding, here are a few quick steps to help determine if it’s working correctly: 1. Check the batteries: Remove the back cover of your remote and replace the batteries with a fresh set, ensuring they are inserted in the correct direction. 2. Test for infrared signal: Point the front of the remote at your smartphone camera. While holding down any button, you should see a flashing light through the camera screen. (For iPhone users, the front-facing camera works best.) If you see the light, your remote is working and may need to be re-paired with your TV. 3. Point the remote correctly: Try pointing the remote directly at the TV from about 5-6 feet away. This can help ensure a clearer signal between the remote and the TV.

Hi Jeffrey, Thanks for sharing your experience with your U7900F TV. Unusual sounds can come from different sources, so first check whether it’s from the TV speakers, an external device (like a soundbar), or the back of the TV. • For external audio, ensure cables are connected to the correct output • If using antenna or cable, check signal strength: Settings > Support > Device Care > Self Diagnosis > Broadcast Signal • Popping sounds from the back may be due to thermal expansion - this is normal and not a malfunction • Run a Sound Test to troubleshoot: Settings > Support > Device Care > Self Diagnosis > Sound Test If the issue continues, please contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat and additional support resources are also available through the Support link on our website. ~ Samsung Advisor
