Code 5295: "dmd blue - temperature sensor short" (Error)
Situation
Damaged wire unit of the
temperature sensors (reference
3 image 4-24) which measures the
temperature of the DMD of the blue
channel.
Defect temperature sensor which
measures the temperature of the
blue channel.
Code 5300: "dmd green - temperature too high" (Error)
This error code is probably preceded by the warning code 5301 : "dmd green - temperature high". The same troubleshooting table
can be applied.
Code 5301: "dmd green - temperature high" (Error)
Situation
Blocked fan of the green channel.
The wire unit of the temperature
sensor (NTC) of the DMD in the
green channel is disconnected from
the Signal backplane.
Defect temperature sensor which
measures the temperature at the
rear side of the DMD of the green
channel.
Code 5303: "dmd green - temperature low" (Warning)
Situation
The electronics of the Light
Processor Unit remains off due to a
low DMD temperature.
Defect temperature sensor which
measures the temperature of the
DMD of the green channel.
Code 5304: "dmd green - temperature sensor open" (Error)
Situation
Wire units of the temperature
sensors are disconnected from the
Signal Backplane.
Damaged wire unit of the
temperature sensors (reference
2 image 4-24) which measures the
temperature of the DMD of the green
channel.
Defect temperature sensor which
measures the temperature of the
green channel.

Solution
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.
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 field. The replacement of this temperature sensor must be done at factory or
at an authorized service center.
Solution
Check if the fan can turn freely.
Check if the wire unit (reference 2 image 4-24) of the temperature sensor (NTC) of the
DMD in the green channel is connected with the Signal backplane.
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 field. The replacement of this temperature sensor must be done at factory or
at an authorized service center.
Solution
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.
Replace the whole Light Processor Unit. Contact Barco for further instructions to repair
the malfunction Light Processor Unit.
Solution
Check if the wire units (reference 2 image 4-24) of the temperature sensors are plugged
into their sockets on the Signal Backplane.
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.
