4. Troubleshooting
Code 5290: “dmd blue - temperature too high” (Error)
This error code is probably preceded by the warning code 5291: “dmd blue - temperature high”. The same troubleshooting table
can be applied.
Code 5291: “dmd blue - temperature high” (Error)
Situation Solution
Blocked fan of the blue channel. Check if the fan can turn freely.
The wire unit of the temperature
sensor (NTC) of the DMD in the blue
channel is disconnected from the
Signal backplane. Check if the wire unit (reference 3 image 4-24) of the temperature sensor (NTC) of the
DMD in the blue channel is connected with the Signal backplane.
Defect temperature sensor which
measures the temperature at the
rear side of the DMD of the blue
channel. Replace the whole Light Processor Unit. Contact Barco for further instructions to repair
the malfunction Light Processor Unit. It is too critical to replace this temperature sensor
in the
fi eld. The replacement of this temperature sensor must be done at factory or
at an authorized service center.

Code 5293: “dmd blue - temperature 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 condensation.
Defect temperature sensor which
measures the temperature of the
DMD of the blue channel. Replace the whole Light Processor Unit. Contact Barco for further instructions to repair
the malfunction Light Processor Unit.
Code 5294: “dmd blue - temperature sensor open” (Error)
Situation Solution
Wire units of the temperature
sensors are disconnected from the
Signal Backplane. Check if the wire units (reference 3 image 4-24) of the temperature sensors are plugged
into their sockets on the Signal Backplane.
Damaged wire unit of the
temperature sensors (reference
3 image 4-24) which measures the
temperature of the DMD of the blue
channel.
1. Repair the wire unit.
2. If not repairable, replace the whole Light Processor Unit. Contact Barco for further
instructions to repair the malfunction Light Processor Unit.
