i have recently moved into a new home and have a bell dish on the roof, so i though perfect time to dust off my hd bell 6131 receiver and hook up, trying to get signal was a breeze, but when i hooked up the sw21 switch i can only receive signal for one dish at a time, if i hard wire directly to the lnb's separatly i get signal on both but once they go into the switch only one shows up ( the one plugged into the dish 1 port on the switch), so at this point i went and bought a new sw21 switch and found that there is nothing wrong with the switch because the new switch gave me the same issues. is it possible that my receiver is fried? like ive said ive had them hooked straight to the receiver separatly and no problems getting signal on either one so that cancels out a lnb error or cable error, and when i run check switch its says missing port1a sat91 odd (even though this is the signal it says im getting) any help is greatly apreciated
