Blocked large dust filter.

Clean the large dust filter or replace with new one. See service manual chapter "Check the large dust filter".

Blocked small dust filter.

Clean the small dust filter or replace with new one. See service manual chapter "Check the small dust filter".

Ambient temperature too high.

Check the ambient temperature at the air inlets of the projector. Make sure that the ambient temperature does not exceed 35°C (95°F).

Malfunction air extraction system.

Check the condition of the air extraction system. The air extraction system must be capable of removing minimum 4 m³/min (140 CFM) per installed DP2K-SLP Series digital projector.

Note: limit the amount of extraction to a maximum of 5m³/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 17 image) which measures the heat sink temperature of the DMD of the green channel.

Malfunction Cinema Control board.

Replace the Cinema Control board. See service manual chapter "Replacement of the Cinema Controller".

Malfunction Light Processor.
