View on the diagnostic LEDs
The Display Interface is located inside the Input & Com munication unit. To view the diagnostic L EDs the Input & Comm unication unit
has to be placed in th e service position as illustrated
below (moved forward and tilted) and the top cover p late has to be r emoved.
CAUTION: 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 insufficient airfl ow.

Comment
1
FPGA CONFIG (red) This LED lit up during the s tart up of the Display Interface B oard and in case the F PGA of the
Display I nterface Board is not c orrectly loaded with the firmware. If this is the case try to reload
the firmware and/or software of the Display Interface Board. If the problem remains replace
the Display Interface Boa rd.
2
HEARTBEAT (green) This LED flashes once a second in normal operation which indicates that the Display Interface
Board works properly. In case of com munic ation problems (e.g. SATA High Speed disconnected)
then this LED flashes twice a second.
3
++5V OK (green) This LED lit up in nor mal condition and indicates that the ++5V standby v oltage from the PMP is
available. The ++5V is generated on the PM P 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 generated ++3.3V and ++1.2V
standby voltages ar e available. These voltages are derived from the ++5V standby voltage.
