I am going by assumption you have a H9S, it has two connections for signal wires from the satellite dish. 1. Is this correct? ( I don;t know how you are expecting cable on it).
2. Do you have signal wires hooked up to both connections? Yes/No answer.
3. What is tuner A set as?
4. What is tuner B set as?
Those are separate questions, if you provide separate answers, it will assist in helping you.
