Troubleshooting
This section provides information and procedur es for resolving common projector issues. If a 
projector issue cannot be resolved, contact a Christie accredited service technician.
Projector does not power on
• Make sure the projector circuit breaker is set to the on position.
• Check the status LEDs on the rear corners of th e projector for a fault condition. A flashing red 
LED indicates an alarm or warning preset with  the projector and a problem that must be 
addressed.
• Use the touch panel controller (TPC) status menu to troubleshoot further.
Lamp does not ignite
• Check and correct all interlock failures.
• Verify that the lamp has been installed and conne cted properly. Verify the condition of the lamp 
and that is not blackened or otherwise damaged.
• Verify the number of hours the lamp has operated . A lamp nearing the end of its operational life 
should be replaced.
Lamp suddenly turns off
• Increase the lamp power.
• Review and correct all interlock failures.
• Ensure the TPC has no temperature or fan RPM warnings. If all fans are running normally and 
the air filters are not blocked, the ambient ai r temperature may exceed the maximum operating 
specification. If possible, reduce the ambient temperature.
• Ensure no heat sources are exhausting into the  projectors intake, or move the projector to a 
cooler environment.
• Verify the number of hours the lamp has operated . A lamp nearing the end of its operational life 
should be replaced.
• Check for a cross-connected condition.

A cross-connection hazard can occur when installin g multiple projectors at once. A fire hazard 
exists if a lamp power supply interlock cable is  connected to a different projector than its lamp 
power cables. 
Flicker, shadows or dimness
• Make sure the shutter is fully open.
• Verify that a LampLOC calibration is not already in progress.
• Perform a LampLOC calibration.
• Increase the lamp power. Lamps which are near  end of service may not operate reliably at a 
lower power setting.
LampLOC not working
•If the  Auto LampLOC  option is not working, on the touch panel controller, tap  Menu > Lamp 
> LampLOC  and adjust the lamp position manually. Observe screen brightness by adjusting 
the X, Y and Z values or use a light meter to check for changes in brightness.
• Check that the flat part of the anode end of th e lamp (if applicable) faces up in the anode yoke.
Touch panel controller is blank
• If the touch panel controller (TPC) display is blank, make sure the TPC communication harness 
is connected securely.
Blank screen, no display of image
• Make sure both lens caps have been  removed from the projection lens.
• Make sure the lamp is on.
• Make sure that all power connections are good.
• Make sure the shutter is fully open.
• Make sure that any test pattern (other than a full black test pattern or test pattern = none)  displays properly.
Cannot communicate with projector
• Make sure the computer and the projector are both connected to the network.
• Make sure that all input devices have the same subnet mask and unique IP addresses.

Inaccurate display colors
• Adjust the color, tint, color space, and co lor temperature settings of the input source. 
• On the touch panel controller, tap  Menu > Configuration > Color Correction  and verify the 
settings are correct.
Display is not rectangular
• Verify the projector is level and the lens  surface and screen are parallel to one another.
• Adjust the vertical offset of the lens mount.
Display has suddenly frozen
• If the source is frozen, restart the source device.
• If the source is not frozen, restart the projector.
Display is jittery or unstable
• Verify that the input device is connected properly . If the input device is not connected properly, 
the projector repeatedly attempts to display an image.
• The horizontal or vertical scan frequency of  the input signal may be out of range for the 
projector. 
For more details, see  Specification on page 72.
Incoming signal(s) problems
The Status tab > Signal group contains information about all the signals that the projector receives. 
A properly configured system shows the frequency an d a status of Master or Locked for each input 
in the selected channel.
• If one or more of the signals are listed as No  signal, verify that the source is properly 
configured and the cables are secure between the source and the projector.
• If one or more of the signals are listed as Inactive, either an incorrect channel has been  selected or the cables are not plugged into the correct inputs.
• If one or more of the signals is listed as Unlocked or Out of phase, the source is not properly  frame locked to the master signal. This usually occurs when two independent sources are not 
locked together. Verify the setup of the source s. If the sources are locked together, contact 
Christie Technical Support for help.

Touch panel controller or projector head 
problems on startup
Check the following to determine if the touch pa nel controller (TPC) or the projector head are 
experiencing problems on startup.
The projector has two sets of LEDs to help distingu ish how far into the start-up process it is when a 
problem occurs.
For more details, see  LED expected behavior on power up  on page 45.
The Projector LEDs or the MCPU board power LED are not on
Solution 1
If AC power has been applied to the projector head, verify the power source.
Solution 2
If the AC power source is good and the AC power  is applied to the projector head, check the LVPS 
and all the harnessing going to it inside the projector.
The MCPU board power LED is not on
If the AC power is applied to the projector head  and the projector’s LEDs turn on, the MCPU board 
or the ABP must be replaced. Replace the MCPU  board first and if the problem is not resolved, 
replace the ABP.
• If replacing the MCPU board, indicate that the Power LED is non-functional.
• If replacing the ABP, indicate that  power did not reach the MCPU board.
MCPU board power LED behavior
• Solid yellow—The MCPU board must be replaced . Indicate that the MCPU board failed to 
initialize.
• Blinking red—The MCPU board must be replaced. Indicate that the MCPU board failed to  initiate the control FPGA.
• Blinking yellow/green—The MCPU board is running in recovery mode and needs a software  upgrade followed by a AC cycle of the projector head.
Touch panel controller does not connect
If the projector LEDs display so lid yellow and the touch panel controller (TPC) has power but does 
not connect, the projector head is fine. However,  a problem could exist between the TPC and the 
MCPU board.
• Disconnect the corded harness to the TPC and reconnect it. You may need to replace the corded harness.
