View on the diagnostic LEDs
The Display Interface is located inside the Input & Communication unit. To view the diagnostic LEDs the Input & Communication unit
has to be placed in the service position as illustrated below (moved forward and tilted) and the top cover plate has to be removed.
C
AUTION
:
Only operate the projector for a few minutes while the Input & Communication unit is moved and
tilted in it’s service position. This to minimize the risk of exceeding the maximum permitted internal temper-
ature limit due to insuf
fi
cient air
fl
ow.

Comment
1
FPGA CONFIG (red)
This LED lit up during the start up of the Display Interface Board and in case the FPGA of the
Display Interface Board is not correctly loaded with the
fi
rmware. If this is the case try to reload
the
fi
rmware and/or software of the Display Interface Board. If the problem remains replace
the Display Interface Board.
2
HEARTBEAT (green)
This LED
fl
ashes once a second in normal operation which indicates that the Display Interface
Board works properly. In case of communication problems (e.g. SATA High Speed disconnected)
then this LED
fl
ashes twice a second.
3
++5V OK (green)
This LED lit up in normal condition and indicates that the ++5V standby voltage from the PMP is
available. The ++5V is generated on the PMP and derived from the ++12V from the Power Box.
4
++3.3V/++1.2V OK
(green)
This LED lit up in normal condition and indicates that the local gen+3.3V and ++1.2V
standby voltages are available. These voltages are derived from the ++5V standby voltage.
