I just found this forum and can't stop reading all there is in here. I was able to get some chinese chanels on sat GE-4 up until last week. Now there is nothing I can do to get it back . I have a Microyal MRX-866 receiver and a 100 cm dish asnd a KU Band V/H LNBF. Can someone give me an idea why the signal would disappear out of the blue. I am pretty new to this and would love to learn more. Thanks.
