BrowneAction:

 

@RunningMan. I've tried turning my LNB 90 degrees both clockwise and anti clockwise, as well as a number of other positions close to 10 o'clock and 4 o'clock but cannot scan any channels at all . Do you have any other suggestions what could be causing my channels to scan on the v instead of h??

 

 

Your amplifier doesn't have more than one Sat input does it?.. as in, one that provides 12v (vertical) and one that provides 18V (Horizontal)to the LNB?

figured it out last night after reading you note about voltages thanks. I saw there were settings on my set top box for LNB power either off, 13v, 18v or 13/18. When I set the power to 18v and do a blind scan, it finds them on the horizontal unlike the 13/18 I had it set to (or the 13v option does).

Something's going wrong there. The 18/13 volts is the DC voltage put on to the coax to power the LNB. Different voltage changes which antenna in the LNB gets used (i.e. which polarity). 13v=vertical 18v=horizontal

 

You should (almost) always have it set to 13/18 unless there is something specific about your setup that requires otherwise. I suspect that something between your STB and LNB is not passing the DC voltage through, and the LNB is staying on one polarity. It's finding the signal on the correct polarity, but the STB is reporting it incorrectly.
