I'm not sure how anyone can help, as I still don't quite understand your satellite set up, or your problem.
I can't even understand your previous post:
"well,i have done something else..i have put the device that settles the lnb with the satelite(sorry,dont know how it is called) directly to the cable that goes to the reciever..I have a clear screen view in the tv that way..even it is hotbird,astra etc..So something must be wrong with the reciever
"
Can you please post some technical information, and better describe your problem.
How many satellite dishes, LNB's, do you have connected to your VU+ receiver?
Are you using a Diseqc switch, which connects multiple LNB's?
What exactly is happening, when you boot up your receiver, are you able to view a channel, for 2-3 minutes, and then it goes off, or something else?
