5. Troubleshooting
Code 7694: “Rod in temp open” (Error)
Situation
Solution
The wire unit of the temperature
sensor (NTC) of the cooling block of
the Light Pipe is disconnected from
the Power Distribution board.
Check if the wire unit (reference 16 ) of the temperature sensor of the cooling block of
the Light Pipe is connected with the Power Distribution board.
Damaged wire unit of the
temperature sensor (reference
16 and ).
Repair or replace the wire unit.
Defect temperature sensor
(reference 16 image 5-31) which
measures the temperature at the
entrance of the Light Pipe.
Replace the temperature sensor mounted on the cooling block of the Light Pipe
(reference 16image 5-31).
Code 7695: “Rod in temp short” (Error)
Situation
Solution
Damaged wire unit of the
temperature sensor (reference
16 image 5-31 and image 5-32).
Repair or replace the wire unit.
Defect temperature sensor
(reference 16 image 5-31) which
measures the temperature at the
entrance of the light pipe.
Replace the temperature sensor mounted on the cooling block of the Light Pipe
(reference 16image 5-31).
Code 7696: “Power supply secondary temp low” (Error)
This error code is probably preceded by the warning code 7697: “Power supply secondary temp low”. The same troubleshooting
table can be applied to.
Code 7697: “Power supply secondary temp low” (Warning)
Situation
Solution
The ambient temperature in the
area of secondary side of the
SMPS is almost below the minimum
required operating temperature of
the projector.
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.
Defect temperature sensor
(reference 1 image 5-31) which
measures the temperature at the
secondary side of the SMPS.
Replace the temperature sensor mounted on the heatsink of the secondary side of the
SMPS (reference 1 image 5-31).

Code 7698: “Power supply secondary temp high” (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.
