Does any of you happen to have any idea why the blue tube/lens assembly on my Data 701s is stuck? I need to adjust the angle to correct convergence but the blue won't bodge. I loosened the two screws on top.

That's not enough! If you look down either side of the blue tube, from the top where the two screws that you loosened are, you'll see two more of the same hex nuts down at the bottom of the tube mounting assembly. You'll need a nutdriver extension to get to them. Loosen those, then the tube will swivel. Don't re-tighten them, I've found that the alignment remains stable even if you just tighten the top two screws.
