I assume you have a c/ku setup
Ku-band is a bit harder to tune than C-band, go to G4-17 press options 6-4-4 select X4 go to channel 603 and bump the dish slowly east from the number you started at, move very slow, if you think you have go to much move back to the number it was and then bump west looking at both the screen and the DC light on the 4dtv, if you get the signal in you may also need to play with the skew to get it to its top quality reading.
