DM500 set up

[iain66]

Hi all trying to set up a DM500 it has pli jade installed, when I try to set up the sats what ever set up I try it will only give me 2 sats. Im using a 4/1 diseqc switch and when I select 4 sats the box just locks up. Has the image become corrupt or is it another prob !!!!

Thanks in advance
