Solution
Look in the projector log files for error entries for this specific laser bank
before it was turned off (other than this error).
These errors are of the format "LDM1–x – LLS bank y [error name]".
Resolve these errors first.
While the projector is in service mode, go to Communicator and go to
Diagnostics >> actual >> Currents. Check the current of the laser bank.
1. No current: Check / reseat the cabling between LDM module and light
source laser bank. Check / reseat the cabling between Light source
and Light source PCB.
2. Current ≤ 630 mA: Check the light sensor functionality, the cabling and
the mounting (check for errors mentioning one of these).
Also check the optical alignment to maximize light output.
Check / reseat the cabling between the LDM board and LLS. Check the
connector on the laser subassembly PCB.
