Laser driver Principle and error codes
There are two identical laser driver PCB’s, de
fi
ned as Board 1 and Board 0, where Board 0 is the lower board and Board 1 is the
upper board.
There are also two identical laser clusters, de
fi
ned as Cluster left and Cluster right, seen from the back side of the projector.
Each cluster again consists of six laser banks, de
fi
ned as Bank0 to Bank5.
For monitoring the status/condition of the laser driver module, there are NTC’s connected to each laser bank and on each driver
output on the laser driver boards. The software will monitor the data from this NTC’s continuously and by an error, a failure message
will occur de
fi
ning the error.
The NTC’s on the Laser driver board are de
fi
nes as “heatsink” in the error message string, and the NTC’s on the laser banks is
de
fi
ned as “bank” in the error message string.
The error message may appear in OSD as illustrated below.
