4. Troubleshooting
Code 5331: "pfc heatsink - temperature high" (Warning)
Situation
Ambient temperature too high.
Blocked front filter.
Malfunction SMPS module
Malfunction Fan Control board.
Code 5340: "dmd red - temperature too high" (Error)
This error code is probably preceded by the warning code 5341 : "dmd red - temperature high". The same troubleshooting table can
be applied.
Code 5341: "dmd red - temperature high" (Error)
Situation
Blocked fan of the red channel.
The wire unit of the temperature
sensor (NTC) of the DMD in the red
channel is disconnected from the
Signal backplane.
Defect temperature sensor which
measures the temperature at the
rear side of the DMD of the red
channel.
Code 5343: "dmd red - 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 red channel.
Code 5344: "dmd red - 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
1image 4-24) which measures the
temperature of the DMD of the red
channel.
Defect temperature sensor which
measures the temperature of the red
channel.

Solution
Check the ambient temperature at the air inlets of the projector. Make sure that the
ambient temperature does not exceed 35°C (95°F).
Clean the filter at the front side of the projector or replace with a new one. See
"Removing the front dust filter", page 333.
Replace the SMPS module, see "Replacement of the Switched Mode Power Supply",
page 281.
Replace the Fan Control board. See "Removing a board in the card cage", page 213.
Solution
Check if the fan can turn freely.
Check if the wire unit (reference 1 image 4-24) of the temperature sensor (NTC) of the
DMD in the red 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 condensation.
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 1 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.
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
