If no, go to step 3
3. Put the square drive socket, with a soldered hexagon key onto a ratchet.
4. Carefully release the 4 lock-down screws, holding the DMD unit onto Prism frame.
Tip: Release the lock-down screws in a way the DMD assembly becomes slightly movable. Keep in mind that at the end of
the re-convergence, tightening the DMD unit can cause some small convergence drift.
5. 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 coincides with the Top left/Bottom right
diagonal line of the center Blue convergence pattern.
- Adjust the control Gb2 & Gb3 simultaneously until the crossing of the center Green convergence pattern coincides with the
Top right/Bottom left diagonal line of the center Blue convergence pattern.
