Green convergence adjustment
6. Continue with re-convergence in center a t the Top and the Bottom of the im age as follows (using tool R847204):
- Adjust the c ontrol Gb3 for coincidence of the diagonal Green line of the Green convergence pattern with the Blue line of the
Blue convergence pattern in the center a t the top of the image.
- Adjust the c ontrol Gb2 for coinci
dence of the diagonal Green line of the G reen convergence pattern with the Blue line of the
Blue convergence pattern in the center at the bottom of the image.
7. Because the different adjustments interact, step 4 and 5 have to be repeated until full coincidence of both convergence patterns
is obtained.
8. Carefully s ecure the position of the DMD as sembly by tightening the 4 lock-down screws.
