try this:
Remove all satellite inputs from the back of the box . Do a switch check
Then reconnect only the 110/119 feed from the Sw34 (leave the 148 off the switch). Do a switch check. - should see SW34 and 100/119.
Add the 148 feed to the switch. -do a switch check.
I'm sure you've tried that, but just in case.
