3. Troubleshooting
Situation Solution
Damaged insulation of the wire unit
of the temperature sensor (ref G
image 3-14), which measures the
temperature of the water cooling
block of the green channel. When
disconnecting the wire unit (ref G/BL
image 3-11) of the temperature
sensor from the Formatter Interface
Board (FIB) the error code is
changed to 7667 : “Green block
temp open”.
• Repair the insulation of the wire unit using shrink sleeve.
• If not repairable, replace the whole wire unit and temperature sensor.
Defect temperature sensor on the
water cooling block of the green
channel. When disconnecting the
wire unit of the temperature sensor
from the Formatter Interface Board
(FIB) the error code is changed to
7667 : “Green block temp open”.
Replace the temperature sensor.

Error 7667 : “Green block temp open”
This error may be preceded by a warning. This error can only appear on the FLM HD series.
Situation Solution
Wire unit (ref G/BL image 3-11)
of the temperature sensor is
disconnected from the Formatter
Interface Board (FIB)
Plug in the wire unit of the temperature sensor into its socket on the Formatter Interface
Board.
Damaged wire unit of the
temperature sensor (ref B
image 3-14) which measures
the temperature of the water cooling
block of the green channel.
• Repair the wire unit.
• If not repairable, replace the hole wire unit and temperature sensor.
Defect temperature sensor (ref B
image 3-14) on the water cooling
block of the green channel.
Replace the temperature sensor.
Error 7668 : “Green block temp high”
This error may be preceded by a warning. This error can only appear on the FLM HD series. Temperature of the water cooling block
of the green channel is to high. If this problem persist the projector will shut down the lamp.
Situation Solution
Interruption of the liquid cooling
circuit.
Check if the loop of the liquid cooling circuit is closed.
