Blue convergence adjustment
4. Continue with re-converging the center at the Top and the Bottom of the image as follows (using tool R847204):
- Adjust the control Bb3 for coincidence of the diagonal Blue line of the Blue convergence pattern with the Red line of the Red
convergence pattern in the center at the top of the image.
- Adjust the control Bb2 for coincidence of the diagonal Blue line of the Blue convergence pattern with the Red line of the Red
convergence pattern in the center at the bottom of the image
5. Because the different adjust
ments 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.
27.4.3.3.3 Readjustment of the plungers
CAUTION: 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.
