View on the diagnostic LEDs
The DVI/HDSDI Input board is located inside the Input & Communication unit. Only the LEDs at the front side (cover plate) are
visible without opening the projector. To view the other diagnostic LEDs the Input & Communication unit has to be placed in the
service position as illustrated below (moved forward and tilted). The other LEDs are then visible through the grid at the sides of the
Input & Communication unit.

tilted in it's service position. This to minimize the risk of exceeding the maximum permitted internal temper-
ature limit due to insufficient airflow.

Comment
This LED lit up in normal condition and indicates that the +12V from the Power Box is available.
This LED lit up during the start up of the DVI/HDSDI Input module and in case the FPGA of the
DVI/HDSDI Input module is not correctly loaded with the firmware. If this is the case try to reload
the firmware and/or software of the DVI/HDSDI Input module. If the problem remains replace the
DVI/HDSDI Input module.
This LED lit up in case something has changed to the applied DVI source. Once the projector
has recognized the DVI source and configured the projector correctly for this source then this
LED goes out.
This LED lit up in normal condition and indicates that the internal clock (inside FPGA) for the DVI
is locked.
This LED lit up in case something has changed to the applied SDI source. Once the projector
has recognized the SDI source and configured the projector correctly for this source then this
LED goes out.
