I’m getting low to no signal strength on transponders 2,4,6,8,10,12 and lower than the odds on the remaining evens. All my odds are in the 90’s while the remaining evens are averaging the 70’s. I’m getting the feeling from other posts that this may be an LNB issue but I’m looking for a little more input. I’ve also noticed that the test channels 490-494 tune fine if I start at 494 and go sequentially down to 490. If I start at 490 and increment up to 494, 490 is the only one that tunes in properly. I either get a searching message or the test banner will randomly flash on and off for the other channels. I don’t notice any missing channels during the day but at night I lose disc, a&e, spke, to name a few. I have a phase III dish with all new RG6 running directly (no splitters or even grounding blocks) to a Hughes E1 and a HR20. All three tunes show similar signal strengths. The other two satellites are getting good strengths or zeros but they remain consistent with and without the channel drops. So am I looking at a bad LNB or do I need some more troubleshooting? Thanks in advance.
