Green convergence adjustment
4. Continue with re-convergence in center at the Top and the Bottom of the image as follows (using tool R847204):
- Adjust the control Gb3 for coincidence of the diagonal Green line of the Green convergence pattern with the Red line of the
Red convergence pattern in the center at the top of the image.
- Adjust the control Gb2 for coincidence of the diagonal Green line of the Green convergence pattern with the Red line of the
Red convergence pattern in the center at the bottom of the image
5. Because the different adjustments interact, step 3 and 4 have to be repeated until full coincidence of both convergence pattern
is obtained.
6. Carefully secure the position of the DMD assembly by tightening the 4 lock-down screws.

AUTION
:
Do NOT adjust the plungers on the DMD assembly, if small convergence drifts have to be corrected
only.
For extreme convergence adjustments, possible in case after the replacement of a DMD assembly, a readjust-
ment of the plungers can be necessary.
Convergence screw is end of course
1. Turn the plunger (A) a few turns counterclockwise.
