4. Troubleshooting
Code 5345: “dmd red - temperature sensor short” (Error)
Situation Solution
Damaged wire unit of the
temperature sensors (reference
1 image 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.
Defect temperature sensor which
measures the temperature 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.
