Hi LeeAnn, Thank you for sharing your experience. If your TV isn’t finding a signal or channels, please try the following steps: 1. First, make sure the external device (such as a cable box or antenna) is securely connected to your TV and powered on. 2. On your remote, press the left directional button to access the Connected Devices menu, then navigate to Sources to switch between input sources and confirm your TV is on the correct one. 3. If you're using a set-top box or cable box, double-check the broadcast signal or the network connection to that external device, as signal issues may be coming from the source itself. If the issue continues or you need additional help with input settings or channel scanning, please don’t hesitate to reach out to Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). Our LiveChat agents are also available at the ‘Support’ link on our website. ~ Samsung Advisor
