Code 6071: “++12v - voltage high”
Situation Solution
Malfunction Cinema Control
board or SMPS board.
Put the projector in Stand-By mode, remove the Lamp House and the
Lamp Cathode Fan assembly to access the Signal Backplane connections
with the SMPS wires (reference 6 Image 25-85). Then, measure on the
Signal Backplane the ++12V voltage on pin 1, 2 or 3 of the connector with
the black wires coming from the SMPS board. See Image 25-85.
If the measured voltage is about 12V then replace the Cinema Control
board. See service manual chapter “Replacement of the Cinema
Controller”, page 217. Otherwise replace the SMPS board. See service
manual chapter “Switch Mode Power Supply (SMPS)”, page 39.
Note: To remove the Light Source, see service manual chapter “Laser
Phosphor Light Source”, page 59. To remove the Anode Fan assembly
see service manual chapter “Replacement of the Anode Fan”, page 84.
Note: The projector must be in Stand-By mode otherwise no voltages are
generated by the SMPS board.

Code 6073: “++12v - voltage low”
Situation Solution
Malfunction Fan Control board
or SMPS board.
Put the projector in Stand-By mode, remove the Light Source and the
Cathode Fan assembly to access the Signal Backplane connections with
the SMPS wires (reference 6 Image 25-85). Then, measure on the Signal
Backplane the ++12V voltage on pin 1, 2 or 3 of the connector with the
black wires coming from the SMPS board. See Image 25-85.

manual chapter “Switch Mode Power Supply (SMPS)”, page 39.
Note: To remove the Light Source, see service manual chapter “Laser
Phosphor Light Source”, page 59. To remove the Lamp Anode Fan
assembly see service manual chapter “Replacement of the Anode Fan”,
page 84.
Note: The projector must be in Stand-By mode otherwise no voltages are
generated by the SMPS board.
Short circuit or bad
connection.
Check the Signal Backplane for bad connections.
Note: To access the SMPS connections with the Signal Backplane the
Lamp House and Lamp Cathode Fan assembly (reference 1 Image 25-84)
has to be removed from the projector.
