Satellite TV companies use satellite TV transponders to deliver TV channels to your satellite dish. Each satellite TV transponder carries multiple satellite channels, and you likely have multiple transponders communicating with your satellite dish at any given time so you can receive all the channels in your package. Troubleshooting a satellite TV transponder can help you when your satellite channels don't have a strong signal.
Things you need
Replacement LNB or receiver
Check the signal on your satellite dish from your television. Access the "System Setup" in the "Main Menu". Click Installation then "Point Dish". The signal meter displays on the bottom of the screen, and you can arrow left or right to switch transponders and satellites to see which signal is low.
Adjust the satellite dish as necessary to improve the transponder signal. Adjust the dish side to side, up and down and by rotating the dish around to obtain a better signal. You can check your signal at the dish with a signal meter plugged into the coax barrel just below the LNB.
Unplug your satellite receiver if adjusting the satellite dish doesn't fix the problem. Satellite receivers can sometimes have a static build-up in them, and unplugging the receiver discharges that static. Wait one minute, and then plug the satellite receiver back into the outlet.
Determine if you have faulty equipment. Replace the LNB first. If that doesn't fix the problem, you may need a new satellite receiver.
