Check the power into the power supply.
Replace the 48 VDC power supply.
No light — Use a multimeter to measure the 12 VDC out of the
low voltage power supply (LVPS). If no power is
measured, replace the 12 VDC LVPS.
2. Check the following harness connections to ensure they are not loose or damaged. If
damaged, replace the affected harness.
• Harness (J129) from the housekeeping board to the laser driver card cage (LDCC)
• Harnesses (J70 and J71) from the laser driver card cage (LDCC) to the laser optical
subsystem (LOS)
If the communication harness from the LBP7 to the LOS is removed, loose, or partially
seated and the system cannot read the LOS information, the lasers do not turn on.
• Communications harness (J110) from the housekeeping board to the 48VDC LVPS
• Communications harness (J112) from the housekeeping board to the 12 VDC LVPS
• Power harness (J111) from the LCDD to the 48 VDC LVPS
• Power harness (J113) from the LDCC to the 12VDC LVPS
3. Check to see if the housekeeping board has two blinking green LEDs.
If the housekeeping board boots, the two LEDs should move from solid green to blinking. If not
blinking, check the following:
• Check the harness (J30) between the housekeeping board and card cage is properly
seated and connected.
• Ensure the proper version of software is installed on the projector.
