Needed tools for r-convergence
For older versions of the light engine, the screwdriver R847204 is used as well for the convergence adjustable
screws as well for the plungers.
How to re-convergence
1. Put the square drive socket (A), with soldered hexagon key, onto a ratchet (B).

2. Carefully release the 4 lock-down screws, holding the DMD unit onto Prism frame (image 27-52).
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 Gb1 until the crossing of the center Green convergence pattern coincide with the Top left/Bottom right
diagonal line of the center Red convergence pattern.
- Adjust the control Gb2 & Gb3 simultaneously until the crossing of the center Green convergence pattern coincide with the Top
right/Bottom left diagonal line of the center Red convergence pattern.
