Anyone experienceing (or ever experienced) issue where even transponders have zero signal strength but odds are fine (in the 30s which is where they were upon installation)... I realized this trying to tune to 367 Smithsonian Channel but get Error 002 screen showing Satellite 72, Transponder 24. Crystal clear weather, no obstructions, did a visual on the dish. I ran diagnostic and says everything is okay. I went to the setup screen and scrolled through and noticed all even transponders are 0 for 72 sat... I get that some are spotbeams so no signal on some is normal. But I have been able to get ch 367 until today.
