12. Servicing
Necessary tools
• 2x R84 7204 : steel s crewdriver with 1/16” ended hex blade.
• R847205 : square drive socket with soldered hexagon key of 2.5 mm

How to re-converge
1. Remov e the convergence cover plate (A) in the top plate by rem oving the necessary screws.

2. Is your p rojector an FLM H D projector?
If yes, Lo osen the 4 screws Cr and the 4 screws Cg on the heat pipes of HD light processors. Then continue with step 3.

If no, go to step 3
3. Put the s quare drive sock et, w ith a s oldered he xagon key onto a ratchet.
4. Carefully release the 4 lock-down screws, holding the DM D 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 cente
r of the image as follows (using tool R847204):
- Adjust the c ontrol G b1 until the crossing of the center G reen 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 pa ttern.
