Before Performing Convergence - Christie CP2230 Service Manual

3.5.1 Before Performing Convergence

• Tap Menu > Service Setup > Digital Convergence > Default to reset the red, green, and blue digital micro-
mirror device (DMD) values to their default settings.
• Ensure image-zoom and centering is complete before performing convergence.
For details, refer to
• Ensure boresight procedures have been completed before performing convergence.
For details, refer to the CP2230 User Manual (P/N: 020-100430-xx).
• Use only a prime lens when performing convergence. DO NOT use an anamorphic or Wide Converter Lens
(WCL) lens.
• The projector should be set up to final maximum usable brightness for the installed application.
• 14FL for Standard 2D
• ~25-30FL for Single Projector 3D with a silver screen
• 25FL per projector for Dual Projector 3D
• Once at the required power setting, the unit should be allowed to come "up to temperature" for at least 15
minutes. Note this nominal operating temperature for monitoring as you perform convergence.
• During convergence, the lid and/or filter side of the projector will be open, causing decreased prism cooling
performance and possible shifts in convergence or DMD focus. The prism temperature should be monitored
during the adjustment and kept within a few degrees of the nominal temperature achieved above by lowering
the lamp power or periodically replacing the cover for a cool-down.
• If the procedure takes longer than an hour, watch for over-temperature alerts when running near 6000W.
Cool-down periods with the shutter closed and cover on may be required.
• The active screen file should be 2048x1080 no crop to prevent any scaling of your reference test pattern.
• Use insulated tools to prevent short circuits (Figure 3-6):
• 2.5mm L-wrench with heat-shrink tubing
• 1.5mm driver with heat-shrink tubing
• Anti-static (ESD) grounding wrist strap
• Typically the green image component can be used as the fixed reference. It is easy to adjust, but very hard to
lock down without causing misalignment.
• DO NOT adjust the spring plunger screws.
• If the assembly will not move when the adjustment screw is turned counter-clockwise:
• Check that the lockdown screws are loosened properly.
• Due to the bulk and tension of the cooling hoses, it may be necessary to help the spring plunger do its job
by gently applying pressure to the edge of the formatter board to slide the assembly in the direction desired
when turning the adjustment screws counter-clockwise.
• Use extreme caution to not damage any components on the board.
• DO NOT force the board, there is no reason it should not move easily with gentle pressure.
