Yes

Yes.

It could be one of the receiver is faulty, causing the LNB to become faulty. It may be that the LNB is faulty. It may just be a co-incidence such as low signal, dodgy connections etc.

Personally I would try another LNB as they are so cheap, unless you happen to have spare boxes to test with.

Thanks i do happen to have a spare sky box pluged it in to test and the same thing is happening when i power it on i lost all the hd channels on the other boxes...... so i persume now it's the LNB thats at fault and needs replacement
