Situation Solution
Note: limit the amount of extraction to a maximum of 5m 3 /min (180 CFM).
Excessive air extraction can dramatically speed-up contamination of the
projector air inlet filters, hence requiring more regular filter cleaning
interventions.
Defect temperature sensor. Replace the temperature sensor (reference 16 Image 25-54) which
measures the heat sink temperature of the DMD of the blue channel.
Malfunction Cinema Control
board. Replace the Cinema Control board. See service manual chapter
“ Replacement of the Cinema Controller ” , page 217.
Malfunction Light Processor. Replace the whole Light Processor Unit. See service manual chapter
“ Light Processor replacement process ” , page 97. Contact Barco for further
instructions to repair the malfunction Light Processor Unit.

Code 5293: “ DMD blue - Temperature low ”
Situation Solution
The electronics of the Light
Processor 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. Replace the temperature sensor (reference 16 Image 25-54) which
measures the heat sink temperature of the blue channel.
Code 5294: “ DMD blue - Temperature sensor open ”
Situation Solution
Disconnected wire of the
temperature sensor. Check if the wire (reference 6 Image 25-55) of the temperature sensor is
plugged into its socket on the Signal Backplane.
Damaged wire of the
temperature sensor. 1. Repair the wire of the temperature sensor which measures the heat
sink temperature of the blue channel (reference 16 Image 25-56) .
2. If not repairable, replace the temperature sensor.
Defect temperature sensor. Replace the temperature sensor (reference 16 Image 25-56) which
measures the heat sink temperature of the blue channel.
