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-

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.
NOTICE! Do not run the projector while performing convergence with the Light Engine Fan
Pack or the Cooling Duct removed. This will cause overheating of the Satellite Formatter
Board FPGA's.
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.
