Hi all,

Some may remember but I posted in here about 3 weeks ago about how my LNB had fallen out of my sky dish so I couldn't use my Sat card. It's finally been a nice day to be able to go up onto the roof to put the LNB back into the dish so i've done that. My prob is that I can't seem to find any channels with the Sat card. I can get a signal but no channels are being found. The signal quality on 12456MHZ is 65-66% I've changed the setting to suit my LNB (the old circle sky one). I don't know if my LNB is stuffed though. I say that because I hooked up my neighbours sky decoder and it was working fine. I've just tried my USB Sat Card and it seems to work fine which is good but still cant seem to pick up any channels with my skystar 2. It worked ok on at another location with a dual LNB (the newer oval sky LNB). Any one have any ideas? I'm completly stumped with this. Here's a print screen


Also that thread that I was talking about from two weeks ago:

Hi Mattie, my only thought is that the LNB is not aligned properly, the quality should possibly be higher, is the skew correct, to adjust the skew rotate the LNB in the holder to optimise quality.

Also set the LO SW to 12750 this will stop the card from outputting 22kHz as currrently you have it set to 11300 which is the LO freq, currently the logic thinks that the currently wanted 12456 is above 11300(SWitch point) so will turn on the 22kHz osc, some LNBs get confused and output nothing if 22kHz is injected to them.

ok. Yeah I thought it may not be aligned properly.

I say that because with my USB tuner I only pick up about half the channels I did before the LNB fell out of the holder. i only pick up 47 channels (thats everything of D1 eg freeview radio and tv channels. Only 28 sky channels showing up. Pretty sure I used to pick up 97 with it.)

Here's a print screen with my USB card:

Also here's all the channels that I pick up:

Is it possible that your new LNB is a different frequency to the last one, i had similiar problem as i went from 11300 to 10750
