LDM driver boards mapping
In each Laser Phosphor projector, there is at least one Laser Driver Module (LDM), with several different
Driver boards mounted in them. An LDM can generate two types of errors:
• An error that indicates a problem on the entire LDM case (LDM 1 – [error message]). This may vary from
wiring going to the LDM to a faulty fan or the printed boards malfunctioning. Error handling involving the
LDM errors mostly involve checking/replacing the wiring, replacing the fan, or swapping the entire LDM
• An error that indicates a problem on one of the LDM driver boards (LDM 1 – x – [error message]). This may
vary from the wiring connected to the LDM board to the board being faulty. Error handling involves either
checking/replacing the wiring connected to the LDM board, or swapping this one board with a board that
serves the same function.
Since there are different types of boards used, the following images should help you identify which board is
located where.

The Blue laser driver board can be swapped with the +36V module and vice versa. None of the
other driver boards can be swapped, except with a board that serves the same function.
