4. Troubleshooting
Code 5345: “dmd red - temperature sensor short” (Error)
Situation Solution
Damaged wire unit o f the
temperature sensors (reference
1 image 4-24) w hich m easures the
temperature of the DM D 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 U nit.
Defect temperature sensor which
measures the temperature of the red
channel.
Replace the whole Light Processor Unit. C ontact Barco for further instructions to rep air
the m alfunction Light Processor Unit. It is too critical to r eplace this temperature sensor
in th e field. The replac ement o f this te mperature sensor must be done at factory or
at an authorized service center.
Code 53 51: “smps primary 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 ex ceed 35 °C (95°F).
Blocked front filt er. Clean the filter at the front s ide of the projector or replace with a new one. S ee

Situation Solution
Malfunction Fan & Motor Control
board.
Replace the F an & Motor C ontrol board. See "Removing a b oard in the card cage",
page 213
Code 5372: “dmd red fan - voltage too low” (Error)
Situation Solution
Malfunction SM PS module. A ll other
fans also report voltage low error.
Replace the SMPS module. See "Replacement of the Switched Mode Power Supply",
page 281
Damaged insulation of the wire unit
of the D MD red fan.
Remove the Light Processor f rom the projector and check the insulation of the wire
unit of the fan.
1. Repair the insulation of the wire unit using shrink sleeve.
2. If not repairable, replace the who le wire unit and fan.
