Early symptoms were missing channels from the 110 Sat, then it starting dropping the signal saying acquiring sat, run check switch. So I tried a check switch then it would come back on for a few hours then do the same cycle again, this time I would unplug the power cords from the 622 and the power inserter trying to reset the switch matrix. Now all I am getting is an X where the ports and sats should be. Anyone have any ideas or fixes? I also replaced the DPP44SW today and am still getting the dreadded X!
