1998 Sony KP-53s65 53" Projection Problem

[pac.attack76]

Set runs normal except for some color offset in some areas. Almost like convergeance but not consistant. Uneven in some areas and even mostly in the bottom right corner. Got the idea to block off the blue lens and that corrected it. What could be causing the blue to be offset? Everything else is good. Tried marking and rotating the adjustments on the neck but nothing happens. I did notice slight movement when i passed the magnectic tip of my screwdriver next to it.
