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 25-82). Then, measure on the Signal
Backplane the +24V voltage on pin 9, 10, 11 or 12 of the connector with
the black wires coming from the SMPS board. See Image 25-82.
If the measured voltage is about 24V then replace the Cinema Control
board. See service manual chapter
“
, page 217. Otherwise replace the SMPS board. See service
manual chapter
Switch Mode Power Supply (SMPS)

, page 39.
Note
: To remove the Light Source House see service manual chapter
, page 59. To remove the Lamp Anode Fan
assembly see service manual chapter

Note
: The projector must be in Stand-By mode otherwise no voltages are
generated by the SMPS board.
Short circuit or bad
connection.
1.
Check the Signal Backplane for bad connections. Ensure that all wires
are well connected (reference 6 Image 25-82).
(Note that the +24V supply is generated on the SMPS board and
enters the Cinema Control board via the Signal Backplane)
2.
Check the wiring (reference 1 Image 25-83) of the Anode Fan for short
circuits.
3.
Check the wiring (reference 3 Image 25-84) of the Cathode Fan for
short circuits.
Note
: To access the SMPS connections with the Signal Backplane the
Lamp House and Lamp Cathode Fan assembly (reference 1 Image 25-84)
