I have a slimline 5 dish with the 4 outputs going into a zinwell 4x6. I have 2 hd dvr, one is a hr22 and one is a hr20. The hr20 receives all of the channels like it is supposed to, and has pretty good signal on the 99 and 103 satellites. around 89-90 on most transponders. For some reason I cannot get a signal on the hr22 on any transponder on the 99 and 103 sats. I have tried moving receivers around to make sure it wasnt a inside cabling issue, and I even bypassed the zinwell switch and still see the same issue. I also swapped b-band converters and even tried a spare hr23 that I have(without using the bband converters) and still have the same issue. I have to think it is a lnb issue but this just has me perplexed. why would the hr20 show good signal and receive all of the channels and the hr22 wont? If it was a lnb you would think that if I take a hr20 out and put a hr22 in its place it would work without any issues? Please help me, this has my head spinning.
