It is difficult to give some advice from far away. Depends on your ability 
to do some testing with the right eqiupment.
Since you still get the OSD,I believe your 14/18 volts are gone. You have to 
measure the LNB-voltage. If both voltages are present without connected LNB 
and voltage goes down with connected LNB (max. 200 mA), then you should 
check your Coax-cable, but also the LNB. Otherwise you could try to get from 
a friend a sat-receiver for testing. If he is doing well, then you have a 
problem with your receiver and you should consult you dealer.
