29. Convergence adjustment
Necessary tools
• 2x R847204 : steel screwdriver with 1/16” ended hex blade.
• R847205 : square drive socket with soldered hexagon key of 2.5 mm
• R847203 : Steel screwdriver with 0.05” ended hex blade
•Allenkey3mm
•Allenkey2.5mm
How to re-converge
1. Remove first the convergence cover plate (A) in the top plate by turning out the necessary screws.

2. Is your projector an FLM HD projector?
If yes, Loosen 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 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 DM
D 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.
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 coincide 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 coincide with the Top
right/Bottom left diagonal line of the center Blue convergence pattern.
