Only takes a few minutes to pull that splitter/amp out of wall and see which cables go where. If you can see on the outside the color of the sat input coax, then see if it goes to the aux/sat connector on back of faceplate. Mine was connected to one of the connections on the splitter/amp, so it had to be moved.
i took mine to dealer for other things and OTA not working. Dealer said no problem found, so I still ended up fixing it myself.
