Hi JPT28, Thank you for your feedback. If your remote isn’t responding or is responding slowly, 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. 4. Clean the remote: Gently wipe the top edge of the remote (where the infrared sensor is located) with a soft, dry cloth to remove any dust or debris that could interfere with functionality.
