5. Troubleshooting
Code 7608: “Green DMD temp high” (Warning)
Situation
Solution
Blocked
fi
lter of the Light Processor
compartment. The other DMD
temperatures are too high as well.
Ensure that the air inlets of the projector are not blocked. Replace a dirty
fi
lter with a
new one.
The liquid cooling circuit of the Light
Processor is not connected with the
main liquid cooling circuit. Most
likely the other DMD temperatures
are too high as well.
Check of the cooling circuit of the Light Processor is connected with the pump and heat
exchanger. See reference 1 & 2 image 5-17.
The wire unit of the temperature
sensor (NTC) of the DMD in the
GREEN channel is disconnected
from the Power Backplane.
Check if the wire unit (reference 19 image 5-18) of the temperature sensor of the DMD in
the GREEN channel is connected with the power Distribution board.
The wire units of two temperature
sensors (NTC’s) have been
swapped. While the temperature of
one DMD is too high, the other will
most likely be too low.
Check if the wire units of all temperature sensors (NTC’s) are plugged in there respective
connector sockets on the Power Distribution board. See image 5-18.

Malfunction Fan Control board.
Replace the Fan Control Board. See "Replacing the Fan control board", page 278.
Defect temperature sensor
(reference 18 image 5-20) which
measures the temperature of the
DMD of the GREEN channel.
Replace the temperature sensor on the cooling block of the GREEN channel.
Code 7609: “Green DMD temp high” (Error)
This error code is probably preceded by the warning code 7608: “Green DMD temp high”. The same troubleshooting table can be
applied to.
Code 7610: “Green DMD temp open” (Error)
Situation
Solution
The wire unit of the temperature
sensor (NTC) of the DMD in the
GREEN channel is disconnected
from the Power Distribution board.
Check if the wire unit (reference 18 image 5-18) of the temperature sensor of the DMD in
the GREEN channel is connected with the power distribution board.
Damaged wire unit of the
temperature sensor (reference
18 image 5-20 and image 5-18)
which measures the temperature of
the DMD of the GREEN channel.
Repair or replace the wire unit.
Defect temperature sensor
(reference 18 XXXX) which
measures the temperature of the
DMD of the GREEN channel.
Replace the temperature sensor on the cooling block of the GREEN channel.
Code 7611: “Green DMD temp short” (Error)
Situation
Solution
Damaged wire unit of the
temperature sensor (reference
18 image 5-20 and image 5-18)
which measures the temperature of
the DMD of the GREEN channel.
Repair or replace the wire unit.
Defect temperature sensor
(reference 18 image 5-20) which
measures the temperature of the
DMD of the GREEN channel.
Replace the temperature sensor on the cooling block of the GREEN channel.
