I think we need a little more information here......let's start at the beginning:
Is your mast plumb?
Are you sure nothing is obstructing your line of sight?
Are you confident that you have the correct data for azimuth, elevation, and skew for your location?
Did you correctly set the elevation? (The mark is the edge of the metal when you look thru the bolt slide slot; sometimes the metal edge is marked with a white line and sometimes it isn't. In any case, it's NOT the clamping bolt itself that is the marker.)
How did you determine the direction for rough-pointing the dish.....Dishpointer.com, or compass, or......? How confident are you that you are pointing generally in the right direction to get started?
What style of LNB do you have? If it's an xku LNB then you tune a new receiver using the signal meter on channel 252 and not 299 (In the attached photo the xku LNB (middle and right) has "eyes" that are more elongated than the older quad LNB. If your LNB resembles the one on the left, then it is NOT xku and you tune to 299 and use the signal meter on that channel.) Note it will also be important to know this information when you get to the point when you authorize your receiver.
When you tune to 299 (or 252 as the case may be) what level of signal do you see? Zero? About 20?
What happened when you entered 4128 into the provider ID? Did the box stay red? Turn to green? The reason you enter this number in the box is that, once you have a signal of, say 50, entering the number causes the box (or someplace on the screen) to turn from red to green IF you are pointing at a Shaw satellite and not some other provider's satellite.
I don't mean to insult your intelligence, but I suspect that the problem is more basic than a faulty LNB or faulty receiver.
Tell us a little more about what your have already done and how you did it.......
