How to replace the formatter?
Do not proceed when you are in a dusty environment!
Dust will fall onto the DMD.
1. Remove the lens holder — "Removing the lens holder", page 99
2. Remove the two top nuts. Be careful not to drop the springs!
Tip:
Look at the position of the nuts: they must be in the same position when remounting a new formatter (focus !).
