Check that you have the correct transponders in your list and that the signal quality is sufficient. Are you getting the SD channels from those two transponders?

Robbo for some reason, one got the channels back last night after another scan, not sure whats occuringit seems that if i turnoff from the mains my fs4200 box the output seems to be ok to the dvbs card , but if the box is turned on at the mains even in standby it causes a problem now " the dvbs card is connected to the output of the fs4200 box"but this hasnt happened before

Yes, as you are using the loopthrough from your Fortec star to supply the signal to another receiver you will get this problem

In order for loopthrough to work properly, you need to turn OFF the first receiver, else it will maintain control of the LNB, and won't let the 2nd receiver get a look in.

Some TPs will work;the ones that are on the same band and polarity as the first receiver was on.

Normally, receivers only have to be in standby to relinquish control of the LNB, apart from Sky digiboxes, maybe the Fortec Stars operate similarly to the digiboxes in that respect.

Remember a UNIVERSAL LNB is a switched device controlled by the receiver, the polarity and band needs to be selected.

My fortec Zeta retains the lnb power in standby. I only found out when I blew a diseqc switch 'cause the power was still coming through from the reciever.
