Thank you guys for all your great input. I never could have made it this far without your help.
Yes Andy and Short Circutz are correct.
The front comes off with 4 screws to reveal a cornucopia of pots!
The ones that I found were as follows:
-V Skew G,B (2 of them for Blue. The one on the VertAdj PCB doesn't seem to do anything. Do they work in unison?)
-V Lin G,B
-V Size G,B,R
-V Cent G,B,R
-V Bow B
-H Skew R,B (2 of them for Blue),G
-H Sub Bow G
-H Sub Skew G
-H Bow B,G
-H Cent R,B,G
-H Size R,B,G
-H Lin B,G
-H Keys B,G
Never having adjusted a projection set before, the task seems daunting.
I managed to get the red lines to mostly converge, but now the blue is off.
Try as I might the way I did it with the Red, I just can't seem to get the Blue lines to converge.
Any advice on where to start, or a good document applicable to this set's calibration?
The green is predominant in the bright areas, so I guess turning up the Blue & Red would solve that one.
As for the Blue lines not converging, I must be missing a step in calibration.
I can attest to the tremendous weight of this monster. I pulled it up a steep icy driveway alone with a hand truck, and it was a very close call as to who was pulling who!
It feels like it rivals my treadmill or snowblower in weight, and they both weigh in at over 200 lbs.
I read somewhere that Elvis, who was notorious for going through a lot of TV's, had the same set. He must have had the prototype if he did, as he died in '77 but this came out in '78. If the prototype didn't have those sturdy casters, I can see it having a role in his death.
