I have bought two openboxs V8S,one for the living room and one for my sons bedroom,i connected them but cant get a signal on any channel,does it matter that I have two boxes coming from my dish.I did have sky working very well on both skyboxes until I disconnected sky and connected the openboxs,now no signal at all,i gave the box to my friend to try at his house and it worked fine in his house.any ideas?
