5. Troubleshooting
Code 7634: "Air out temp short" (Error)
Situation
Damaged wire unit of the
temperature sensor (reference
11 image 5-27 and image 5-28).
Defect temperature sensor
(reference 11 image 5-27) which
measures the temperature at the air
outlet (projector rear side).
Code 7635: "Air out temp open" (Error)
Situation
The wire unit of the temperature
sensor (NTC) of the air outlet
is disconnected from the Power
Distribution board.
Damaged wire unit of the
temperature sensor (reference
11 image 5-27 and image 5-28).
Defect temperature sensor
(reference 11 image 5-27) which
measures the temperature at the air
outlet (projector rear side).
Code 7636: "Engine air temp low" (Error)
This error code is probably preceded by the warning code 7637: "Engine air temp low". The same troubleshooting table can be
applied to.
Code 7637: "Engine air temp low" (Warning)
Situation
The ambient temperature in the
area of the projector is almost below
the minimum required operating
temperature of the projector.
Defect temperature sensor
(reference 16 image 5-29) which
measures the temperature inside the
Light Processor compartment.

Code 7638: "Engine air temp high" (Warning)
Situation
Blocked filter of the Light
Processor compartment. The
DMD temperatures are probably too
high as well.

Solution
Repair or replace the wire unit.
Replace the temperature sensor at the air outlet channel.
Solution
Check if the wire unit (reference 11 image 5-28) of the temperature sensor is connected
with the power distribution board.
Repair or replace the wire unit.
Replace the temperature sensor at the air outlet channel.
Solution
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 condensate.
Replace the temperature sensor mounted on the Light Processor assembly (reference
16image 5-29).
Solution
Ensure that the air inlets of the projector are not blocked. Replace a dirty filter with a
new one.
