• Defective laser driver board—high voltage current source (HVCS) boards or low voltage current
source (LVCS) board
• Defective harness between the LOS and driver board
• Issue with the LOS or backplane (LBP7) board
• LOS problem
Resolution
Caution! If not avoided, the following could result in minor or moderate injury.
• Only Christie qualified technicians who are knowledgeable about the hazards associated with
laser use, high-voltage, and high temperatures generated by the product are authorized to
assemble, install, and service the Christie Laser Projection System.
1. Swap the board from the laser driver with another laser driver.
• If the problem follows the board, replace the faulty board.
• If the problem does not follow the board, the problem could be the harness, with the LOS,
or a backplane board problem. Proceed to step 2.
2. If the harness (J150, J151, J152, J156, J157, J158, or J159) from the LOS to a laser driver
board is not seated properly, removed, or damaged, the Cross Plug Detected warning is
displayed.
a. Check the logs to determine which one of the seven slots is causing the Cross Plug
Detected warning to focus on the HVCS or LVCS board affected at that slot. Reconnect or
replace the harnessing going to that board.
b. If the warning persists, swap in a different HVCS board and if the warning persists on the
same slot, replace the LBP7.
c. If the warning follows the board, replace the affected HVCS or LVCS board.
3. To determine if an LOS or backplane problem exists, check the warnings and use the
interrogator logs to narrow down what the issue is. Contact Technical Support.
For example, if the system reports a high temperature warning from one of the devices, an
LOS problem is indicated.
Formatter Fault error has occurred
One of the following Formatter Fault errors appear in the Status tab of display panel for either the red,
green, or blue formatter boards
• Formatter Detection Fault
• Formatter Initialization Fault
• Formatter Runtime Fault
Resolution
Follow these steps to determine the cause of the Formattter Fault error.
The examples used in the steps below are based on a Formatter Detection Fault error on the red
formatter board and use the cables labeled as red and green.
1. Remove top cover.
