Guys, I soldered out the mentioned coil and soldered what ever 1mH coils available I had, guess what!? Nothing! then I soldered 2 wires to the bases of the coil and tested near 30 coils!!!!! nothing happend to high band, finally I opened shell of original coil but wires seemed to be ok and no sign of burning or overheating was visible! :( so I soldered the original coil to the board again. The PDF file I downloaded exactly explaines my problem but mine seems to be more complicated, for the coil is not the component to be blamed!! I will highly welcome any other suggestions. :-cry1:-cry1:-cry1:-cry1

I am writing this final post for those who may encounter the same problem.
If you are sure that your dish, lnb and other equipment are 100%ok and all software settings are correct, then you can proceed to test your hardware (Skystar). Because most of the components on this card are SMD (surface Mountable Device), they may easily became disconnected from board by smallest force withought any visible symptoms. so, look at Mr.Albert Houwer's description of coil replacement at http://joshyfun.blogspot.com (only if you are experienced enough with electronic boards and soldering), then if that was not the case, look at the nearby component for defection. In my case, one miniature resistor, 220ohms, R17 was a little above the board! bringing me alot of trouble and preventing the card from receiving high band.
Hereby I want to thank Rolfw and Orthoclipse for their guides to me and my especial thanks to Mr. Albert Houwer whose instructions lead to solving my problem. :) :)

hello, first thanks to all on your information..
I have the same problem with my ss2 - the coil was faulty, and I changed it.The capacitor near it (10V,100uF) was also faulty and I changed it (I put 16V,100uF).Everything else works fine except 22kHz. Does anyone know where is the source of 22kHz signal, on the board? Or what else could be problem? Just to mention, coaxial cable was short-circuited and it was the main source of problems :(
Thanks for any info

hi, just ignore the previous post, I solved the problem. It was coil, capacitor and LNB. Everything's ok now. These messages helped me a lot. thanx
