Malfunction Cinema Control board or SMPS board.

Put the projector in Stand-By mode and open the right-front cover door. Then, measure on the Signal Backplane the +24V voltage on one of the three PTC components (lower pin) . See image image.

1. If the measured voltage is about 24V then replace the Cinema Control board. See service manual chapter "Replacement of the Cinema Controller".

2. Check the Signal Backplane for bad connections or short circuit. Ensure that all wires are well connected (reference 6 image).

   Note: fan2 voltage is derived from the +24V. The +24V supply is generated on the SMPS board and enters the Cinema Control board via the Signal Backplane.

3. If persist, replace the SMPS board. See service manual chapter "Replacement of the SMPS board".

Note: The projector must be in Stand-By mode otherwise no voltages are generated by the SMPS board.
