Don't rule out an LNB...I had one go out on a Dish approx 15 months after install. DirecTV technician didn't believe that it would have been dead so fast but it solved my signal problems. Also better mounted the dish so that it's more wind-resistant. You can "sign up" for the Protection plan, call them the next day and schedule the install, then after the install drop the plan. Can save you $$$.
