5. Troubleshooting
Code 7709: “Power supply primary PFC temp low” (Warning)
Situation
Solution
Blocked air inlet channel.
Ensure that the air inlet at the front bottom of the projector is 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 SMPS is
disconnected from the Power
Distribution board.
Check if the wire unit (reference 1 image 5-33) of the SMPS control is connected with the
power distribution board.
The wire unit of the temperature
sensor on the SMPS is damaged.
Check if the wire unit (reference 3 image 5-35) of the temperature sensor on the SMPS
is not damaged. Replace sensor and wires if necessary.
Malfunction Fan Control board.
Replace the Fan Control Board. See "Replacing the Fan control board", page 278.
Defect temperature sensor
(reference 3 image 5-35) which
measures the temperature at the
primary side of the SMPS.
Replace the temperature sensor.

Code 7710: “Power supply primary PFC temp high” (Warning)
Situation
Solution
The wire unit of the SMPS is
disconnected from the Power
Distribution board.
Check if the wire unit (reference 3 image 5-33) of the SMPS control is connected with the
power distribution board.
The wire unit of the temperature
sensor on the SMPS is damaged.
Check if the wire unit (reference 3 image 5-35) of the temperature sensor on the SMPS
is not damaged. Replace sensor and wires if necessary.
Defect temperature sensor
(reference 3 image 5-35) which
measures the temperature at the
primary side of the SMPS.
Replace the temperature sensor.
Code 7711: “Power supply primary PFC temp high” (Error)
This error code is probably preceded by the warning code 7710: “Power supply primary PFC temp high”. The same troubleshooting
table can be applied to.
Code 7712: “Power supply primary PFC temp open” (Error)
Situation
Solution
Damaged wire unit of the
temperature sensor (reference
3 image 5-35 and image 5-33).
Repair or replace the wire unit.
Defect temperature sensor
(reference 3image 5-35) which
measures the temperature at
heatsink of the primary side of the
SMPS.
Replace the temperature sensor mounted on the heatsink of the primary side of the
SMPS (reference 3image 5-35).
