The place i am currently staying at has an old sky satellite dish on the roof, and they have a zinwell 7500 box, so i connected it all up as shown on the freeview site, but unfortunately it says no signal.  So basically the questions are, is it ok/does it work using a sky dish?  And everything seems to be connected up correctly,running rg6 coaxial cable from sat to box.  I tried resetting to factory  but it still says no signal, any help would be much appreciated thankyou. :)

There could be many possible reasons, when was the dish last used?, is it still aligned? Have you traced the cable all the way from the Sat to the box, is it chewed/broken anywhere. Thats just to start with, I'd test the box on another dish, could be the LNB is faulty.  Might just need to get an expert.

You might need to set the lnb frequency in the Zinwell to match the dish lnb frequency. If the Zinwell is set to 11300 try changing it to 10750. A lot of old sky lnbs out there are nearing the end of their life span. I had to set my lnb frequency 5MHz lower to make it work.

don't mess with me.... i'm the hd insider....

Does the zinwell auto tune, ie is it a freeview approved unit?

Yeah the lnb frequency is the main decision you have to make. As has been mentioned here a few times, the sky dual/oval/10,750 lnbs have been failing a bit lately, so if it really doesn't work it could be that the lnb is faulty.

Two main choices for lnb frequencies are 10750 and 11300.
22khz tone should be off.
