3. Troubleshooting
Situation
Solution
Damaged insulation of the wire
unit of the temperature sensor (ref
D image 3-17) which measures
the temperature at the front of the
DMD of the blue channel. When
disconnecting the wire unit (ref B/FR
image 3-11) of the temperature
sensor from the Formatter Interface
Board (FIB) the error code is
changed to 7685 : “Blue front DMD
temp open”.
•
Repair the insulation of the wire unit using shrink sleeve.
•
If not repairable, replace the light processor. Contact Barco for further instructions
to repair the malfunction light processor.
Defect temperature sensor which
measures the temperature at the
front of the DMD of the blue channel.
Replace the light processor. Contact Barco for further instructions to repair the
malfunction light processor.
Error 7685 : “Blue front DMD 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 B/FR 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. See image 3-11.

the front of the DMD of the blue
channel.
•
Repair the wire unit.
•
If not repairable, replace the light processor. Contact Barco for further instructions
to repair the malfunction light processor.
Defect temperature sensor which
measures the temperature at the
front of the DMD of the blue channel.
Replace the light processor. Contact Barco for further instructions to repair the
malfunction light processor.
Error 7686 : “Blue front DMD temp high”
This error may be preceded by a warning. This error can only appear on the FLM HD series.
Situation
Solution
The wire unit of the temperature
sensor at the front of the DMD is
mistakenly switched with one of the
wire units of the other temperature
sensors of the light processor.
Check if all wire units of the temperature sensors are plugged into their respective
sockets on the Formatter Interface Board. See image 3-11.
The wire units of the TEC’s (Peltier
element), mounted on the common
cooling block of the heat pipes, are
mistakenly switched.
Check if all wire units of the TEC’s for front cooling are plugged into their respective
sockets on the Formatter Interface Board. See image 3-11.
No thermal contact between heat
pipes and common cooling block
due to loose screws.
Check if the four screws, which attach the heat pipes of the involved channel to the
common cooling block, are fastened. See image 3-18.
Malfunction TEC between heat
pipes and common cooling block.
Use the “diode test” of a multi-meter
to check out the TEC. Polarity
doesn’t matter. The TEC is not
OK in case the measured value is
higher then 0,01 volt.
Remove the light processor from its compartment and replace the malfunction TEC.
If problem persist contact Barco for further instructions.
