Need more info to be able to help with this. Does it power-up, i.e standby LED on, does it then come out of standby after a few minutes when u press the power button, how do u know u dont have supply to the LNB, u shud have either 13v or 18v DC, dependant upon what channel ur tuned to. If ur technical i can send u PDF CCT diagrams, what model is it....(Ex STB engineer)
