Recently bought second hand Pace 3100 and installed all myself. Picking up sky channels fine and have installed raven quad lnb with new dish. Did signal test and input one shows good signal quality and strength. Input 2 shows no signal at all. Swapped cables around and still have good signal on Input one and no signal on Input two. so I guess LNB and dish OK Does this automatically mean there is a problem with the box or can dish/lnb be moved to get good signal at both inputs? If it can only be the box, any ideas what problem may be? Any help will be gratefully received.
