I have Dish 211 Hd reciever and the other week lost all channels. Checked signal strength and none was showing. Rechecked switch. Showed correct switch, but still no signals from any of the 3 sats. Hooked my 129LNB (while still on my dish) to my neighbors Dish 500 setup (which is located about 2 feet from my setup) with a SW21 switch. Found switch, sats, and all strength was there. Is my LNB (110-119 DP) bad? Or could I leave it setup this way? With being setup as is, will the HD channel be affected in any way? Thanks for any advise.
