2. Carefully release the 4 lock-down screws, holding the DMD unit onto Prism frame (image 27-59).
Tip: Release the lock-down screws in a way the DMD assembly becomes just movable. Keep in mind that at the end of the
re-convergence, tightening the DMD unit can cause some small convergence drift.
3. Start the re-convergence in the center of the image as follows (using tool R847204):
- Adjust the control Bb1 until the crossing of the center Blue convergence pattern coincide with the Top left/Bottom right diagonal
line of the center Red convergence pattern.
- Adjust the control Bb2 & Bb3 simultaneously until the crossing of the center Blue convergence pattern coincide with the Top
right/Bottom left diagonal line of the center Red convergence pattern.
