I have been trying to setup a friends satellite dish, but having an interesting problem which I am hoping some here can point me in the right direction.

The story: I have used a satlink meter to make sure dish is aligned. I get 90% strength and 80% quality plugging directly into dish and at the lounge end of the cable. My meter blind scans all freeview and sky channells. I can see and hear the freeview channels on my satlink meter. I can blind scan all freeview channels into a very old satellite box and they work on the tv. How ever, this is where it gets interesting.

They have a Hills HSM075 satellite box which will not scan for channels and I tried a DTVSB1 box as well. The DTVS will blind scan all freeview and sky channels but comes up with bad signal when you try to watch a channel. I can get both of these boxes to scan all channels and work on my satellite dish perfectly. My dish and friends dish are identical dish sky dishes with the sharp LNB.

If I then try either box on friends satellite dish they both show bad signal, but my really old box and my satlink meter work fine. I have checked the cable at friends is on continuos piece of rg6 cable.
What am I missing?

Failing LNB. With a blind can you will pick up TP frequencies that are a few MHz out no problem. With a STB that is looking for specific transponders, you'll have no luck.

Check the exact frequencies report by the blind scan and see if they correspond with the exact transponder frequencies, or of they are a bit off - if they're off, replace the LNB.

I did try another LNB. It was another sky sharp one, still with the same results. Maybe I need to get a new LNB and try that.

There's a lot of half dead Sharp LNBs around. The definitive way is to check the transponder frequencies showing in the blind scan
