How to Replace the LNB Switch on a Dish
Replacing the LNB, or low-noise block converter, on your satellite dish is a job that you can certainly get done without calling the satellite guy. The LNB is the most important portion of the dish: it receives the satellite signal, converts it and sends it down your RG-6 coaxial cable to your satellite receiver, which then in turns it into your television's picture. Portions of the LNB are made from light plastic, which can easily crack with your dish out in the elements.

Locate the screw that holds your LNB in place. This will be underneath the dish's arm, close to the LNB. Remove this screw and pull the LNB out from the dish's arm carefully. A wire or two will pull out with it, connected to the LNB.

Disconnect the wires from your LNB. Twist the ends of the wires until they come loose. Keep note of which wire is connected to which port if you have more than one; this can make a difference in your dish's alignment.

Re-connnect the wires to your new LNB in the same ports they were in the old one. Insert the pin from wire into the pin-sized hole of the port, then twist the wire to secure it in the port. Repeat with the other wire(s), if necessary.
