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).
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.
Replace the Fan Control board. See "Removing a board in the card cage", page 213.
