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.
