If you come across this problem this may help, had this problem myself and helped someone with the same problem last weekend - and he was just about to throw his receiver in the bin.
Symptoms - no signal or sat finder beeps intermittently.
Cause - LNB not getting voltage through coax cable caused by the screen not contacting in moulded plugs.
Solution - check with a meter if you can or just remake the ends.
You can slice the rubber sleeve/foot off of the connector and it will still work as an interference fit once you have remade the end.
I have also found that having the central conductor at a slight angle helps as well as sometimes this will give a better connection.
