maybe you have the wrong lnb type selected for echo 8 in antenna setup, if you have dish-pro selected - delete channels and scan using standard lnb type.
FRIEND HAS THE SAME PROBLEM. NO SIGNAL IN TP'S WITH H . IF U TRY TO CONVERT THEM TO V USING 25600 METHODE STILL SAME PROBLEM. I THINK THE LNB'S ARE DP HAVE PRPOBLEM WITH PANSAT IN HORIZONTAL TP'S
