—
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.
3. If confirmed the projector has power out of the LVPS but the system does not boot, check the
LEDs on the housekeeping board (HKBB).
•
If no light on the housekeeping board, ensure the 12V harness (J112) from the LVPS to
the housekeeping board is properly seated and connected.
•
If the housekeeping board boots, the two LEDs should be blinking. If not blinking, ensure
the harness (J30) between the housekeeping board and card cage is properly seated and
connected. If the display panel is on, it indicates a functioning card cage.
•
If the harness is connected and properly seated between the two boards, replace the
housekeeping board.
4. Check the display panel and keypad are functional.
•
Check to ensure the display panel harnesses (J30 and J32) are connected and properly
seated, or are not damaged. If damaged, replace the affected harness.
•
Check the card cage. Turn on the projector and from the web interface check for any
errors on the Status page. If an error is listed, correct the error.
•
If the display panel and/or keypad are not functional, replace the user interface module.
