Code 7620: “Ambient temp high” (Warning)
Situation
Solution
Ambient temperature high.
Reduce the ambient temperature. Make sure that the ambient temperature is within
specs: lower then 40°C (104°F).
Blocked air inlet channel.
Ensure that the air inlets are not blocked. Provide a suf
fi
cient free area at the front of the
projector so that fresh air can freely enter the air inlet channel.
The wire unit of the ambient
temperature sensor (NTC) is
disconnected from the Power
distribution board.
Check if the wire unit (reference 10 ) of the ambient temperature sensor is connected
with the power distribution board (reference 10 image 5-23)
Malfunction Fan Control board.
Replace the Fan Control Board. See "Replacing the Fan control board", page 278.
Defect temperature sensor
(reference 10 image 5-22) which
measures the temperature at the air
inlet (projector front side).
Replace the temperature sensor at the air inlet channel.

Situation
Solution
The wire unit of the ambient
temperature sensor (NTC) is
disconnected from the Power
Distribution board.
Check if the wire unit (reference 10 image 5-23) of the ambient temperature sensor is
connected with the power distribution board.
Damaged wire unit of the ambient
temperature sensor (reference 10
image 5-22 and image 5-23).
