Hi everyone! Hope you can help me. Got a 522 installed and activated yesterday. It worked great last night and this morning. Tonight when I got home from work, only tuner 1 will lock on to the signal, tuner 2 runs a aquiring satellite signal and just sits there. It locked on earlier for about one minute then went back to the aquiring signal. Checked all connections and every thing seems ok. Have a quad dp lnb. 508 in another bedroom is fine and main tv in living room is fine. Help!
