Today I tried to help a buddy of mine change his Old Dish with a new Oval one with three LNBs. He has two R10s and is about to add a HD dvr of some sort. But we were only able to get signal on the B and C satellite. B was in the high 90s and C was in the low to mid 90s. BUT the A satellite had no signal at all on all transponders. Any ideas? We plan to resume the battle tomorrow. I checked the receiver this morning and we are getting many more than three transponders on Sat B. Before we get back on the roof we are receiving on Sat. B the transponders: 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, and 32. On Sat. C we are receiving: 8, 10 , and 12. Is this still and aiming issue? Sorry for the repost we are running out of time I am about to assume the LNB group is bad and buy a new one at best buy or Fry's.
