3.5 DMD Convergence Procedure
Always wear an ESD strap when replacing the light engine or any other circuit
board; however, it is not recommended to wear a strap while converging a live unit, but to
instead ensure frequent contact with the bare metal of the projector to prevent static build-
up.
NOTICE:
This document is written only as a supplement descriptive guideline for information on
convergence. Personal tool preference, mechanical experience and individual techniques are all variables that
make this document a subjective tool for use only by experienced professional technicians. For full Christie
guidelines and company recommended tools, refer to Using the Christie Convergence Tool Kit (P/N: 013-
100074-xx) and Adjusting Convergence (P/N: 013-100139-xx).
The projector uses three separate DMD panels to produce three separate red, green and blue image
components. To ensure the most accurate color representation across the whole image it is essential the three
panels are perfectly aligned so that all pixels line up. The following convergence procedure outlines how to
achieve this. Only Christie authorized service technicians should perform the following procedure. Read this
entire section before adjusting convergence.
