If the Scientific Atlanta receiver displays a 'No Signal' message or has no signal when switched on, it could be due to several reasons. First, ensure all satellite/antenna/video cables are properly connected. Second, verify that your satellite antenna is correctly aligned. Third, confirm that the correct installation settings are in use and that an adequate signal level is present. Also, check that your TV is set to the correct channel for receiving satellite signals, as configured in the Audio/Video Setup menu. Finally, ensure your subscriber services are currently authorized.
