Over a year ago I replaced my satellite with a Weingard in motion satellite and it worked fine until today. I have been parked for about two weeks and have had good reception until now. The only difference is the temperature. It went from in the high seventies to the mid thirties in one day and on the second morning of cold weather the satellite no longer is sending signals to the receiver. I checked all my receivers and they all do not work. I also reset the satellite and it went through the search mode and stopped after searching but I can't tell whether or not it is actually locked on to the satellite. How can I diagnosis the dish? Any suggestions as to a fix.
