4. Troubleshooting
Code 5305: "dmd green - temperature sensor short" (Error)
Situation
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.
Code 5310: "lamp - temperature too high" (Error)
This error code is probably preceded by the warning code 5311 : "lamp - temperature high". The same troubleshooting table can
be applied.
Code 5311: "lamp - temperature high" (Warning)
Situation
Ambient temperature too high.
Blocked filters.
Malfunction air extraction system.
Malfunction lamp anode fan or lamp
cathode fan.
Code 5314: "lamp - temperature sensor open" (Error)
Situation
Wire unit (reference 3 image 4-25)
of the temperature sensor is
disconnected from the Signal
Backplane.
Disconnected wire (reference
2image 4-25) units between Signal
Backplane and temperature sensor
in the air outlet channel of the
projector.
Damaged wire unit of the
temperature sensor (reference
1 image 4-25).
Defect temperature sensor
(reference 1 image 4-25).

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 the ambient temperature at the air inlets of the projector. Make sure that the
ambient temperature does not exceed 35°C (95°F).
Check filters. Clean filthy filters or replace with new ones.
Check customer air extraction system for adequate extraction. The air extraction system
must be capable of removing minimum 6,65 m³/min or 235 CFM per installed digital
projector.
Check the speed and voltage of the lamp anode and lamp cathode fan. Replace any
malfunction fan.
Solution
Plug the wire unit of the temperature sensor into its socket on the Signal Backplane.
Check the connection between the wire units. The connection is made behind the back
cover.
1. Repair the wire unit.
2. If not repairable, replace the whole wire unit and temperature sensor.
Replace the temperature sensor. Temperature sensor is visible through the air outlet
on top of the projector.
