4. Troubleshooting
Code 5331: “pfc heatsink - temperature high” (Warning)
Situation Solution
Ambient temperature too high. Check the ambient temperature at the air inlets of the projector. Make sure that the
ambient temperature does not exceed 35°C (95°F).
Blocked front fi lter. Clean the fi lter at the front side of the projector or replace with a new one. See
"Removing the front dust fi lter", page 333.
Malfunction SMPS module Replace the SMPS module, see "Replacement of the Switched Mode Power Supply",
page 281.
Malfunction Fan Control board. Replace the Fan Control board. See "Removing a board in the card cage", page 213.
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 Solution
Blocked fan of the red channel. Check if the fan can turn freely.
The wire unit of the temperature
sensor (NTC) of the DMD in the red
channel is disconnected from the
Signal backplane. 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.
Defect temperature sensor which
measures the temperature at the
rear side of the DMD of the red
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 5343: “dmd red - 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 red channel. Replace the whole Light Processor Unit. Contact Barco for further instructions to repair
the malfunction Light Processor Unit.
Code 5344: “dmd red - temperature sensor open” (Error)
Situation Solution
Wire units of the temperature
sensors are disconnected from the
Signal Backplane. Check if the wire units (reference 1 image 4-24) of the temperature sensors are plugged
into their sockets on 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.
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.
