Solution
Malfunction Fan Control 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

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.
