What all has been replaced?
Is there a barrell connector in the wall plate? If so, take the cable loose and tell us what color the plastic insert is.
Have they pulled the plate off and checked the cable behind it? What kind of connector is in there, is the center conductor long enough?
Are there any splices in the attic/basement? If so, what are the components? What about the connectors and center conductors there?
What about the ground block? Is it a 3 GHz model or one of the old zinc 1 GHz style?
All splices and their components need to be checked out. Dish told us the 1 GHz stuff wouldn't pass the higher frequencies (couldn't tell you, I only run 3GHz stuff). Dish also told us that on dual tuners running DPP this type of problem could be caused by the reciever not getting enough power through the surge protector. Hook it up directly to the outlet and see if that fixes it.
The simplest way to eliminate the wiring is by running a line straight from the reciever to the LNB. Bypass everything else. If the problem still exists, that would point toward the LNB, or the power strip.
