5. Troubleshooting
Code 7612: “Blue DMD temp low” (Error)
This error code is probably preceded by the warning code 7613: “Blue DMD temp low”. The same troubleshooting table can be
applied to.
Code 7613: “Blue DMD temp low” (Warning)
Situation Solution
The electronics of the Light
Processor Unit remains off due to a
low DMD temperature. Make sure that the ambient temperature is within specs: higher then 10°C (50°F). Let
the projector acclimate. Do not ignite the lamp, otherwise there is a risk for condensate.
Defect temperature sensor
(reference 17 image 5-21) which
measures the temperature of the
DMD of the BLUE channel. Replace the temperature sensor on the cooling block of the BLUE channel.

Code 7614: “Blue 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
BLUE 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 BLUE 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.
