CONVERGENCE OVERVIEW
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. However, the fan packs can be removed for a short
time to access the adjustment screws. If this is necessary you can verify the
temperature at the TPC status window.
The projector has three separate DMD panels to produce three separate red, green and blue image
components. To get 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.
