You must be looking at the screen with the new hd dvr verification screen.?
Are you using prewire in the house? There are many things to check that could be causing the problem. There are error codes that go with those errors but i don't have a list of what each error message means. Maybe someone else on here might.
Try this if at all possible. Run 2 new coax lines straight from the dish to the receiver and rerun the test again. If it works, it is more than possible a line/connection problem. If you still get the errors it is more than possible a dish problem.
There is a signal threshold for each transponder. I was having a problem with the 99c transponder 3. After a little fine tuning i got it to pass
