771 searching for signal message

i just have a technician out and he changed out the SLIMLINE 3 LNB and got my services back up. 

but i'm still getting this error message on some channels.

i have a SWM-8 setup.  i attached the test and configuration setup.

one of the four cables that come into the SWM isn't getting a signal.   he spliced one of the cable near the dish to test the signal.  i'm wondering it this splice is causing the issue or is it something else. 

i never had this problem with my slimline 5 LNB and didn't have the issue with the Slimeline 3 until recently.

so i moved the cables around the SWM input until i got a configuration with the least amount of errors, but still getting 771 code sporadiacly

so when i run the satelite install on any reciever in the house

i get check marks on all but the 13V 103* setting.   is this normal or should i get DTV to come out again. 

i knew more than the last tech they sent out so i'm a little worried.
