when trying to locate the satellites..it is better to leave the switch out..go direct from 110 lnb find the satellite then repeat for 119.. then you can hook up your switch..use port 1-119 use port 2-110 and make sure those setting match in your installation menu.
and if you have been connecting and disconnecting cables and switches with power on, then yes your disque will probably be fried.
as long as you have the proper elevation, azimuth you will find it...make sure you have the correct lnb type selected in installation 2 or it will not show up on the screen even though it is there..sometimes if you if you move to where you select sats it will show up on different ones..if so you can scan it there also.
119 lnb power - on lnb type - single (legacy twin LNB1) either one worked for me lnb freq - 11.250 22 khz - off disque switch - 1.0 committed - 1 legacy sw - off
110
lnb power - on lnb type - single (legacy twin LNB) either one worked for me lnb freq -11.250 22 khz - off disque switch - 1.0 committed - 2 legacy sw - off
