Hi, I've got a similar problem so I thought I'd keep it in this thread.
I've got a 510 receiver and a superdish (105) and I just moved. I moved my dish myself, and have had few problems except the occasional signal loss because my dish is just temporarily fixed in the ground for now and gusting winds sometimes adjust it. However, the past few days I have lost all my local channels.
I've rebooted my receiver countless times, no dice. I was getting a strong lock on the 110 and 119 satellites, but when I run a check switch the result is
1. 119 - Dual
2. 110 - Dual
3. X - N.C.
I switched the cables going into ports 2 and 3 on my DP34, and ran a check switch. The result was
1. 119 - Dual
2. X - N.C.
3. 110 - Dual
I then completely switched the cables for the 110 and 105 lnb's to check and make sure I didn't just have a bad cable from the 105 lnb to the DP34. The result was that the 110 sat still showed up, but the 105 still reported N.C.
I called a local sat guy who had a brand new 105 lnb and picked it up. I swapped my 110 and 119 lnb's from my 105 arm to the new 105 arm and then hooked it all up again. The result is still the same,
1. Conn - Dual
2. Conn - Dual
3. X - N.C.
(the last time I ran the check switch my satellite was not in the ground anymore, as I'm preparing to permanently affix it with a strong pole mount)
Am I getting the N.C. reading simply because I haven't locked in the 105 sat? Shouldn't I at least get a "Conn" reading on my switch test indicating that an lnb is connected, just not locked onto a satellite? Because I get a "Conn" reading on my 110 and 119 lnb's, when they're not on the dish locked in (everything is in my basement right now while I troubleshoot) it leads me to believe that I should at least get a "Conn" reading on the 105 lnb as well, until it is out on the dish and locked in, in which case it should read as "105."
Surely I haven't got 2 bad 105 lnb's, right? Could this be something wrong with my switch? We have had freezing weather at night and temps up into the 40s during the day here, and when the installers originally swapped out my Dish500 for the SuperDish, they just used three zip ties to fasten my DP34 to the pole mount instead of using a weatherproof box like I see around town nowadays.
Unless there could be something wrong with my switch which disallows it to recognize my 105 lnb, I'm stumped. What should I try next?
